Which Doctor Treats Lead Poisoning? Who to See and How to Find Them

For most people, the doctor who treats lead poisoning is the one they already have: a child’s pediatrician or an adult’s family doctor, working together with the local health department. When blood lead levels are high, the CDC tells that doctor to bring in specialists, such as a Pediatric Environmental Health Specialty Unit (PEHSU), Poison Control or a medical toxicologist.

In short: start with your own doctor or your child’s pediatrician and ask for a blood lead test. Your local health department can often test too, and it follows up on high results. Workers exposed on the job can also see an occupational medicine clinic. At higher levels, the CDC’s guidance has the doctor consult a PEHSU or Poison Control, and at the highest levels a medical toxicologist or a pediatrician experienced in lead poisoning, sometimes with a hospital stay. For urgent questions call Poison Control at 1-800-222-1222; for a seizure, collapse or trouble breathing, call 911.

This page sums up what the CDC, ATSDR, NIOSH, OSHA and the specialist networks publish. It is not medical advice; only a provider who knows the patient can decide on care.

Who to see first: your own doctor

The CDC’s advice to parents is simple: if you believe your child has been exposed to lead, talk to your child’s health care provider, who may order a blood lead test. Most children with lead in their blood have no obvious symptoms (see lead poisoning symptoms). Our blood lead test guide explains the finger-prick and blood-draw versions and what a result means.

The CDC’s clinical guidance is written for these providers: it tells them what to do at each blood lead level, from education and repeat tests to reporting, home investigations and specialist referrals. Your regular doctor is not just a gatekeeper; for most people with lead exposure, that doctor manages the follow-up. Our guide to lead screening for children covers when children are usually tested.

For adults, NIOSH, the CDC’s worker-safety institute, says that if you or someone in your household works with lead, tell your doctor, and ask about a blood lead test if your employer does not offer routine testing. See lead testing for adults for who should ask.

Your local health department’s lead program

The CDC says health care providers and most local health departments can test for lead in the blood. The CDC also funds childhood lead poisoning prevention programs run by state and local health departments. When a child’s result is at or above the CDC’s blood lead reference value of 3.5 µg/dL, the CDC tells the doctor to report it to the state or local health department, which may then follow the child, help the family find the source and arrange a home investigation where local rules require one.

What each program offers is set by the state or city, so call your county or city health department and ask for its lead program. Our lead poisoning test page lists other places to get tested.

Lead poisoning specialists

Three kinds of specialists come up in official guidance, working alongside your own doctor.

Pediatric Environmental Health Specialty Units (PEHSU)

The PEHSU network was created in 1998 by ATSDR, the CDC’s agency for toxic substances, with support from the EPA. It has ten regional units based at academic health institutions, each covering a group of states, with experts in pediatrics, environmental medicine and clinical toxicology. According to pehsu.net, pediatric and obstetric providers, public health departments and other health professionals can contact their regional unit for a consultation on children’s or pregnancy-related environmental exposures, lead included. ATSDR says the units also work with parents, schools and community groups.

Note for families: the national PEHSU site says the units do not provide clinical services. Your doctor can consult the regional unit. Find yours on the PEHSU regions page, which lists the states each region covers with phone and email contacts. We could not find a published statement on whether consultations cost anything, so ask your regional unit.

Medical toxicologists

Medical toxicologists are physicians who specialize in poisoning. The CDC’s guidance names them for the highest blood lead levels, where the provider consults “a medical toxicologist or pediatrician with experience in treating lead poisoning” about treatment. The American College of Medical Toxicology (ACMT) runs a public Find a Toxicologist directory that can be filtered by state and by inpatient or outpatient services. Some poison centers are listed in the directory too.

Occupational medicine doctors, for workers

Most adults with high blood lead are exposed at work, according to NIEHS. OSHA’s lead standards require employers to provide medical surveillance, including blood lead tests, without cost to employees who are or may be exposed at or above the action level for more than 30 days a year. The Association of Occupational and Environmental Clinics (AOEC) keeps a clinic directory of member clinics that see workers with job-related illness and people exposed to environmental hazards.

Who to see, when, and how to find them

Who	When to see them	How to find one
Pediatrician or family doctor	First stop for any lead worry, a blood lead test and all follow-up	Your own provider, or ask your health department where to go
Local health department	Testing, follow-up of high results, home investigations where required	Your county or city health department’s lead program
Poison Control	Someone swallowed something that may contain lead, or you have urgent questions	1-800-222-1222, free and confidential, 24/7
PEHSU	Your doctor wants expert advice on a child’s or pregnancy exposure (CDC: at 20 µg/dL and above)	pehsu.net, by region; no clinical care
Medical toxicologist	Very high levels (CDC: 45 µg/dL and above), usually through your doctor or a hospital	ACMT Find a Toxicologist; ask your doctor or Poison Control
Occupational medicine clinic	Lead exposure at work	Your employer’s medical program; AOEC clinic directory
Emergency room / 911	Seizure, collapse, trouble breathing or other severe symptoms	Call 911

What the CDC tells doctors to do at each level

Which specialist joins in depends on the blood lead level. In the CDC’s guidance for children’s providers (dated August 21, 2025), each step includes the ones before it:

Below 3.5 µg/dL: the regular doctor teaches families about lead sources, checks development and diet, and retests based on age and risk.
3.5 to 19 µg/dL: the doctor reports to the health department, takes an exposure history, arranges a home investigation as required locally and schedules follow-up tests.
20 to 44 µg/dL: a full history and exam, and the doctor contacts a PEHSU or Poison Control for guidance.
45 µg/dL and above: the doctor consults a medical toxicologist or a pediatrician experienced in lead poisoning about treatment, and admits the child to a hospital as soon as possible if there are signs or symptoms. The CDC also tells doctors to consider admission when the home is not lead-safe and no lead-free housing is available.

Our blood lead levels page puts these numbers in context, and lead poisoning treatment explains what the CDC and ATSDR say about care, including why there is no home treatment.

When to call Poison Control or 911

Poison Control, at 1-800-222-1222, connects you to your local poison center, where trained nurses, pharmacists or doctors answer; HRSA says the call is free, confidential and open 24 hours a day. Call if a child swallowed a paint chip, a fishing weight or anything else that might contain lead, or if you have urgent questions. For a seizure, collapse or trouble breathing, call 911. MedlinePlus (National Library of Medicine) also lists vomiting or seizures as reasons to call 911.

What to bring to the appointment

Test results: every blood lead result you have, with dates, and whether each was a finger-prick or a blood draw from a vein.
Home information: the year your home was built (paint before 1978 may contain lead), any recent renovation, peeling paint, known lead pipes, and any home or water test results. See lead paint testing and lead in water testing.
Products: names or photos of imported spices, foods, candies, remedies, cosmetics, pottery or toys you use, or the items themselves if the doctor asks. See lead in household items.
Work and hobbies: jobs and hobbies of everyone in the home, since NIOSH notes lead dust can come home on work clothes and shoes.

Questions to ask the doctor

Was this a finger-prick or a venous test, and does it need to be confirmed?
When should the next blood lead test be?
Will you report this to the health department, and will someone check our home?
Should other people in the household be tested?
Do you plan to consult a PEHSU, Poison Control or a medical toxicologist?

For what usually happens over the following months, see lead poisoning recovery.

Insurance and Medicaid

The CDC says many private insurance policies cover the cost of blood lead testing, and for children enrolled in Medicaid the cost is covered by the Centers for Medicare and Medicaid Services. A 2016 CMS bulletin states that all children enrolled in Medicaid are required to receive blood lead screening tests at 12 and 24 months, and any child aged 24 to 72 months with no record of a previous test must receive one. The same bulletin says Medicaid can reimburse lead investigations in the home of a child with elevated blood lead. Workers covered by OSHA’s lead standards get medical surveillance from their employer at no cost. Ask your insurer about specialist visits.

Frequently asked questions

What kind of doctor treats lead poisoning?

Usually a pediatrician or family doctor, with the local health department. At higher levels the CDC tells that doctor to consult a PEHSU or Poison Control, and at the highest levels a medical toxicologist or a pediatrician experienced in lead poisoning.

Is there a lead poisoning specialist near me?

Check ACMT’s Find a Toxicologist directory, your regional PEHSU on pehsu.net, and the AOEC clinic directory if the exposure is from work. Your doctor or health department can also refer you.

Can I call a PEHSU myself?

PEHSUs mainly advise health professionals, but ATSDR says they also work with parents, and each region lists a phone and email. They do not provide clinical care.

Should I go to the emergency room for lead exposure?

Call 911 for severe symptoms such as a seizure, collapse or trouble breathing. Otherwise, call Poison Control at 1-800-222-1222 or your doctor; they will tell you whether you need to be seen right away.

Does insurance pay for a blood lead test?

The CDC says many private plans cover it, and Medicaid covers it for enrolled children. OSHA requires employers to provide it free to covered workers.

Lead Poisoning in Pregnancy: Risks, Sources and Breastfeeding

Lead poisoning in pregnancy matters because lead in the mother’s blood reaches the baby: the CDC says lead readily crosses the placenta, and lead stored in the mother’s bones can be released into the blood during pregnancy. Most people with lead exposure feel nothing, so the way to find it is a blood lead test, ordered by your health care provider when your history shows a risk.

Mother holding her swaddled newborn by a sunny window

In short: the CDC says lead in the blood during pregnancy can increase the risk for miscarriage, cause the baby to be born too early or too small, hurt the baby’s brain, kidneys and nervous system, and cause the child to have learning or behavior problems. Common sources include eating clay or soil (pica), imported remedies, cosmetics and spices, lead-glazed pottery, renovation of pre-1978 homes, and lead dust brought home from a household member’s job. The CDC recommends a risk check at the first prenatal visit and a blood test if any risk is found, and it says mothers below 40 µg/dL should breastfeed.

This guide explains what the CDC, the World Health Organization (WHO) and the FDA say. It is not medical advice. Your prenatal care provider decides whether you need a test and what a result means. For urgent questions about a possible poisoning, call Poison Control at 1-800-222-1222.

How lead reaches the baby

The WHO explains that lead is stored in the teeth and bones, where it builds up over time. That stored lead is why pregnancy is a special case.

Through the placenta. The CDC’s 2010 Guidelines for the Identification and Management of Lead Exposure in Pregnant and Lactating Women say lead crosses the placenta by passive diffusion and has been measured in the fetal brain as early as the end of the first trimester. That is why the guidelines call preventing exposure “particularly important.”
From the mother’s own bones. The CDC pregnancy page says lead stored in adults’ bones can be released into the blood during pregnancy, so blood lead levels can rise. The WHO says the same: bone lead released during pregnancy “becomes a source of exposure to the developing fetus.” Past exposure, even years before, can matter.
After birth, through breast milk. The CDC says mothers can also expose infants to lead through breast milk (see breastfeeding below).

What lead exposure during pregnancy can do

The CDC’s “Risk Factors and Pregnancy” page lists four effects of lead in the blood during pregnancy. In its words, lead can:

Increase risk for miscarriage
Cause the baby to be born too early or too small
Hurt the baby’s brain, kidneys, and nervous system
Cause the child to have learning or behavior problems

The WHO fact sheet on lead says lead exposure during pregnancy “can cause reduced fetal growth and preterm birth,” and that there is no level of exposure to lead known to be without harmful effects.

The 2010 CDC guidelines add detail: studies link prenatal exposure, even with maternal levels below 10 µg/dL, to lower fetal growth and neurodevelopment; lead has been associated with high blood pressure in pregnancy; and the evidence on miscarriage and preterm delivery is more limited and mixed. The CDC has not named any blood lead level as safe for mother or baby. For the long-term picture, see effects of lead poisoning.

Common sources of lead for pregnant people

The 2010 guidelines name the groups most likely to be exposed: workers in certain jobs, recent immigrants, and people with habits such as pica or renovating older homes.

Pica: eating clay, soil and other non-food items

Some pregnant people feel an urge to eat clay, soil, plaster or paint chips. The CDC guidelines advise never eating or mouthing non-food items because they may contain lead, and note that pica is common in many parts of Africa, Asia and Central America. Tell your provider: it is a recognized risk factor, not a judgment.

Imported remedies, cosmetics, spices and candies

The guidelines advise avoiding imported cosmetics, food additives and medicines that may contain lead, such as azarcon, kohl, kajal and surma, and using caution with candies, spices and foods brought from abroad. The FDA warns that kohl can cause lead poisoning and advises asking a provider to test pregnant or nursing women who used it; it has also cautioned about some Ayurvedic products and issued alerts on ground cinnamon. Our guide to lead in cinnamon and spices lists the FDA alerts.

Pottery, crystal and metal cookware

The CDC guidelines advise against using imported lead-glazed pottery, pewter or brass for food, leaded crystal for drinks, and chipped or cracked dishes. The FDA says some traditional pottery labeled “lead free” still released lead, and in December 2024 it warned that certain imported aluminum, brass and Hindalium cookware can leach lead. See lead in pottery and dishes.

Renovation and old paint

The guidelines say to stay away from repair, repainting, renovation and remodeling work in homes built before 1978 and to avoid deteriorated lead paint. Work should be done by others using lead-safe renovation (RRP) practices while you are out of the home.

Jobs and hobbies, yours or a household member’s

The guidelines advise avoiding jobs or hobbies involving lead and guarding against take-home lead dust if a household member works with lead, such as in pre-1978 renovation or lead battery making or recycling. Dust carried home on clothes, shoes or skin settles in the car and home. Pregnant women at 10 µg/dL or higher should be removed from work exposure to lead. Our guide to lead testing for adults covers the jobs on the CDC list and the NIOSH advice for workers.

Concerns at a glance

Concern	What CDC / WHO say	What you can do
Lead reaching the baby	Lead crosses the placenta; bone lead can be released into the blood during pregnancy (CDC, WHO)	Tell your provider about any past or present exposure, even years ago
Pregnancy outcomes	Can increase risk for miscarriage and cause the baby to be born too early or too small (CDC); reduced fetal growth and preterm birth (WHO)	Ask about a lead risk assessment at your first prenatal visit
Pica	Never eat or mouth clay, soil, pottery or paint chips (CDC 2010)	Mention any cravings for non-food items to your provider
Imported remedies, cosmetics, spices	Avoid imported products that may contain lead, such as azarcon, kohl, kajal, surma (CDC 2010); kohl can cause lead poisoning (FDA)	Stop using the product and bring it to your appointment
Renovation	Stay away from renovation in homes built before 1978 (CDC 2010)	Let others do the work lead-safely while you are away
Take-home dust	Take precautions if a household member works with lead (CDC 2010)	Work clothes and shoes stay at work or are washed separately
Nutrition	Eat a balanced diet with adequate iron and calcium (CDC 2010); “a diet high in iron and calcium” (CDC)	Ask your provider before taking any supplement

How to lower lead exposure during pregnancy

The CDC puts it simply: the best way to prevent lead in the blood is to prevent lead exposure. Based on the CDC guidelines and pregnancy page:

Keep lead dust out. Stay away from renovation in pre-1978 homes. Work clothes and shoes of household members who work with lead stay out of the living space. The CDC advises wet-mopping floors and other flat surfaces.
Skip imported remedies, cosmetics, unlabeled foods and lead-glazed pottery, and check FDA alerts for spices you already have.
Eat well. The guidelines say to eat a balanced diet with adequate intakes of iron and calcium and to avoid cigarettes and alcohol. The CDC pregnancy page says doctors may suggest “eating a diet high in iron and calcium.” Do not start supplements on your own, and never use products sold to “remove lead.”
Check your home. Our free home lead risk checker walks you through the usual sources room by room.

Testing during pregnancy

The CDC does not recommend testing all pregnant women in the US. Instead, providers are asked to look for risk factors as part of your work, home and lifestyle history, at the earliest prenatal contact, and to order a venous blood lead test if even one risk factor is found. Clinics that serve communities with known risks may test everyone. The CDC pregnancy page adds that if you think you may have been exposed, you should talk to your provider about a blood lead test.

A sample questionnaire reprinted in the guidelines (Minnesota Department of Health) asks about lead jobs or hobbies at home, eating clay, soil, plaster or paint chips, dusty renovation in a pre-1978 home, high lead in your water, folk remedies or cosmetics not sold in regular stores, and homemade pottery or leaded crystal.

At 5 µg/dL or higher, the guidelines recommend follow-up testing, a search for the source and testing of the newborn. Our guide to blood lead levels has the CDC schedule and explains the units, and lead testing for adults covers who should ask. Home kits do not test people; they check paint, dust, soil or water (see lead poisoning test).

Lead and breastfeeding

Lead can pass into breast milk, but the CDC still calls breast milk the most complete and ideal food for infants in their first year. Its guidance, from the 2010 guidelines and the current CDC breastfeeding page:

Below 40 µg/dL: mothers should breastfeed. The CDC page says women with levels of 5 µg/dL up to below 40 can breastfeed, while their providers watch the baby’s levels.
40 µg/dL or higher (confirmed): pump and discard breast milk until the mother’s level drops below 40, then begin breastfeeding.
Testing breast milk for lead is not recommended. The blood test is what guides decisions.
If the baby’s level rises or does not come down, providers look for other sources first. Only if none is found, and the mother’s level is above 20 µg/dL with the baby at 5 µg/dL or higher, may a temporary pause be considered.

For formula that needs mixing, the guidelines say to use water only from the cold tap, flushed for at least 3 minutes, or bottled or filtered water known to be free of lead. More on water at lead in water testing.

What to ask your provider

Based on my job, home, hobbies and the products I use, do I have a risk factor for lead? Should I have a blood lead test?
I had lead exposure in the past (or I grew up or lived abroad). Could stored lead matter in this pregnancy?
If my level is 5 µg/dL or higher, when will you retest, and will the baby be tested at birth?
Is there anything about my diet I should change? Should I take any supplement, or avoid one?
What does my level mean for breastfeeding?

Bring any imported remedy, cosmetic or spice you use to the appointment. For more on lead and health, start at our lead poisoning hub.

Frequently asked questions

Can lead pass from mother to baby during pregnancy?

Yes. The CDC’s 2010 guidelines say lead readily crosses the placenta, and both the CDC and the WHO say lead stored in the mother’s bones can be released into the blood during pregnancy and reach the baby.

Should every pregnant woman get a lead test?

The CDC does not recommend testing everyone. It recommends a risk assessment at the first prenatal contact and a blood lead test if any single risk factor is found. If you think you were exposed, ask your provider.

Is there lead in breast milk?

It can, but the CDC says mothers below 40 µg/dL should breastfeed; at 40 or higher, pump and discard until the level drops below 40. Testing breast milk is not recommended.

Why does my provider ask if I eat clay or dirt?

Eating non-food items such as clay, soil, plaster or paint chips (pica) is a known source of lead in pregnancy, and it is on the CDC’s list of risk factors. A “yes” usually means a blood lead test, which helps protect you and the baby.

Can Lead Poisoning Kill You? Lead Poisoning Statistics and Deaths

Yes, lead poisoning can kill, but in the United States today it almost never does so quickly. The World Health Organization says lead exposure was linked to more than 3.5 million deaths worldwide in 2023, mostly through its effects on the heart and blood vessels after years of exposure, while sudden deaths from very high levels, usually in young children who swallowed something made of lead, are rare in the US and are reported as individual cases.

Public health lab technician handling blood sample tubes

In short: most lead-related deaths come from long-term, lower-level exposure that raises blood pressure and the risk of heart disease in adults. Fast, fatal poisoning is rare in the US but has happened, for example in a 4-year-old who swallowed a lead charm in 2006. Lead levels in US children have fallen by about 96% since the late 1970s, yet millions of homes still have lead paint hazards and about 4 million lead water pipes remain in the ground. No safe blood lead level is known, so prevention and testing still matter. For a possible poisoning, call Poison Control at 1-800-222-1222, or 911 in an emergency.

This page gathers public statistics from health and housing agencies and one peer-reviewed study. It is not medical advice. Talk to a doctor or your local health department about your own situation.

Can lead poisoning kill you?

It can, in two very different ways.

Slowly, through the heart and blood vessels. This is where most lead-related deaths come from. The WHO says lead contributes to high blood pressure, heart and blood vessel problems and kidney damage in adults. Over many years that raises the chance of dying from a heart attack or stroke.
Quickly, from a very high dose. A large amount of lead in a short time, for example from a swallowed lead object, can cause serious brain injury (lead encephalopathy) and death. In the US this is now rare.

So the honest answer to “can lead poisoning kill you” is yes, but the main danger for most people is quiet and long-term, not sudden. More in our guide to the effects of lead poisoning.

Lead poisoning deaths: what the numbers really say

The WHO figure: 3.5 million deaths worldwide

The WHO’s lead fact sheet, dated June 10, 2026, cites the Institute for Health Metrics and Evaluation (IHME): more than 3.5 million deaths globally in 2023 were attributed to lead exposure, “primarily due to cardiovascular effects.” It is a modeled estimate, not a tally of death certificates that say lead poisoning.

The US estimate: about 412,000 deaths a year

A 2018 study in The Lancet Public Health by Bruce Lanphear and colleagues followed 14,289 US adults whose blood lead was measured in a national survey from 1988 to 1994, and linked them to death records through 2011. The researchers estimated that 18% of all deaths, equivalent to about 412,000 a year, could be attributed to lead, including about 256,000 cardiovascular deaths and 185,000 deaths from ischemic heart disease.

This is a peer-reviewed research estimate, not an official CDC count. It is also based on blood lead levels from the late 1980s and early 1990s, when the average adult level in the study was 2.71 µg/dL; lead levels have fallen a great deal since, as the children’s data below show. It shows how large the long-term effect may be, not today’s yearly toll.

Is there an official US count?

We could not find a current CDC or NCHS page that publishes a national yearly count of deaths from lead poisoning, so we do not quote one. A heart attack in someone with years of exposure is not recorded as lead poisoning.

Fatal lead poisoning in children is rare, but it has happened

In a 2001 report the CDC called fatal lead poisoning in US children rare, crediting public health measures. Two cases published in its Morbidity and Mortality Weekly Report (MMWR):

New Hampshire, 2000. A 2-year-old girl who had arrived three weeks earlier with her refugee family died with a blood lead level of 391 µg/dL. The CDC called it the first reported death of a child from lead poisoning since 1990, and the investigation pointed to lead paint and dust in the home.
Minnesota, 2006. A 4-year-old boy died of lead encephalopathy after swallowing a heart-shaped charm that tested at 99.1% lead. It came on a bracelet given free with a pair of shoes; his blood lead level was 180 µg/dL. The bracelets were recalled.

For comparison, the CDC’s reference value for children is 3.5 µg/dL, so these children had levels more than 50 times higher. Keep small metal jewelry and charms away from young children; see lead and children. If a child may have swallowed a metal object, call Poison Control at 1-800-222-1222 right away, or 911 for severe symptoms such as a seizure.

How common is lead poisoning in the US?

It depends on what you count, because no level of lead is known to be safe.

Children: much lower than before, but not zero

The EPA’s America’s Children and the Environment report shows the median blood lead level of US children ages 1 to 5 fell to 0.6 µg/dL in 2017–2020, a 96% decrease since 1976–1980. The biggest drop followed the removal of lead from gasoline. The median was higher for children in families below the poverty level (0.8 µg/dL) than for other children (0.6 µg/dL).

What “1 in 40” means

The CDC’s blood lead reference value of 3.5 µg/dL was set at the 97.5th percentile of blood lead in US children ages 1 to 5, using national survey data from 2015 to 2018. By definition, that means about 2.5% of young children, roughly 1 in 40, were at or above 3.5 µg/dL in that survey. It does not mean children below 3.5 are safe. The CDC says the value is a screening tool to find children with more lead than most, and it is not health-based. Our guide to blood lead levels explains the numbers in more detail.

Why there is no single national case count

States report blood lead tests to the CDC, and the CDC publishes those tables for 2017–2022. But the CDC itself warns that this data is not a population-based estimate, is not representative of the US or even of a whole state, and cannot be compared accurately between states because testing and case definitions differ.

Adults: mostly a workplace issue

The CDC’s National Institute for Occupational Safety and Health (NIOSH) tracks adults with blood lead of 10 µg/dL or more through its ABLES program. Among adults at that level whose source was known, about 90% were exposed at work, and the National Institute of Environmental Health Sciences (NIEHS) names jobs such as mining, construction, welding and battery manufacturing. See lead poisoning in adults for more.

Where the risk still comes from

Old paint and dust. The EPA says about three-quarters of US homes built before 1978 still contain some lead-based paint. HUD’s American Healthy Homes Survey II, done in 2018–2019, found lead-based paint in 34.6 million homes and at least one lead-based paint hazard in 29 million. About 3.3 million homes with a hazard had a child under 6 living there.
Water pipes. The EPA estimated in its November 2025 update that about 4 million lead service lines remain across the country. Read more in our guide to lead pipes.
Jobs and hobbies. Most adults with high blood lead were exposed at work.
Products. The CDC lists some imported candies, traditional medicines, toys and jewelry as sources.

What these statistics mean for you

Three practical steps, in line with CDC, EPA and HUD advice:

Test people, not guesses. Most children with lead in their blood have no obvious symptoms; the CDC calls a blood test the best way to know. Ask your doctor; our guide to the lead poisoning test explains how it works.
Find the source. In a pre-1978 home or one with a possible lead service line, testing paint, dust and water shows where lead is.
Get help early. Ask your doctor or local health department.

For risks, sources and who to call, see our lead poisoning guide.

Frequently asked questions

Can lead poisoning kill you?

Yes. Very high levels can cause serious brain injury and death, which is rare in the US today. Far more often, years of exposure raise blood pressure and the risk of heart disease, and the WHO links more than 3.5 million deaths worldwide in 2023 to lead, mostly through the heart and blood vessels.

How many people die from lead poisoning in the US each year?

We found no official yearly count. A 2018 peer-reviewed study estimated about 412,000 deaths a year attributable to lead, mostly from heart disease, in adults exposed in 1988–1994.

How common is lead poisoning in children?

Much less common than in the past: the median level in children ages 1 to 5 fell 96% since 1976–1980. No safe level is known, so ask your child’s doctor about testing.

Is Lead Poisoning Reversible? Recovery, Timelines and What Lasts

Lead poisoning is partly reversible. Once exposure stops, the amount of lead in the blood goes down, but lead stored in the bones can stay for decades, and the CDC says some effects of lead poisoning “can be permanent and disabling,” especially on a child’s developing brain.

In short: you can recover in the sense that blood lead levels fall once the source is found and removed. ATSDR, the CDC’s toxic-substances agency, estimates the half-life of lead in adult blood at 28 to 36 days, about a month, while lead in bone has an apparent half-time of one to two decades. Damage that has already happened, such as effects on learning and IQ, may not reverse, which is why the CDC focuses on stopping exposure early and on support services for children. There is no home treatment or detox. If you are worried, call your doctor, your local health department or Poison Control at 1-800-222-1222.

This page sums up what the CDC, ATSDR, NIEHS and the World Health Organization publish. It is not medical advice; only a provider who knows the person can say what to expect.

What “recovery” from lead poisoning means

Recovery means two things: will the lead leave the body, and will the effects go away? Official sources answer them separately.

For the lead itself, the answer is mostly yes, slowly. ATSDR’s course for doctors says repeat blood tests are used “to verify the decline in BLL after lead sources have been reduced or eliminated.” A falling blood lead level is the main sign of recovery. How fast it falls depends on how high the level was, how long the exposure lasted, the person’s age, and how much lead has built up in the bones.

For the harm, the answer is less certain. NIEHS states that “many effects are permanent,” and official sources do not promise that any specific effect will reverse. Our guide to the effects of lead poisoning lists what each agency describes, and our lead poisoning hub covers the basics.

How long does lead stay in your body?

ATSDR describes three places lead goes: blood, soft tissues, and bones and teeth. The bones and teeth of adults hold about 94% of the body’s lead; in children, the figure is about 73%. Lead leaves the blood much faster than it leaves the bone, and bone can feed lead back into the blood for years. ATSDR’s 2020 Toxicological Profile for Lead puts it plainly: lead “is retained in the body for decades.”

The published timeframes below are averages and ranges from studies, not a forecast for any one person.

Timeframe	What happens	Source
About a month (28 to 36 days)	Estimated half-life of lead in adult blood: roughly half of the lead in the blood is gone in that time, if no new lead comes in and bone does not add more.	ATSDR, Case Studies in Environmental Medicine: Lead Toxicity
1 week to 2 years	The apparent half-time of lead in blood “varies with age and exposure history.” Long or heavy exposure builds bone stores that slow the decline.	ATSDR Toxicological Profile for Lead (2020)
8 to 38 months	Apparent blood half-times estimated in one study of children exposed at ages 2 to 3. ATSDR notes these include lead moving from bone back into blood.	ATSDR Toxicological Profile for Lead (2020), citing Manton et al. 2000
2 weeks to 9 months between tests	The CDC’s follow-up blood test schedule for children, set by the confirmed level: higher levels are checked sooner.	CDC, Recommended Actions Based on Blood Lead Level
1 to 2 decades	Apparent half-time for elimination of lead from bone.	ATSDR Toxicological Profile for Lead (2020)
Several decades	One part of bone lead is “essentially inert,” with an elimination half-time of several decades; ATSDR’s course says it “stores lead for decades.”	ATSDR Toxicological Profile (2020); ATSDR Case Studies in Environmental Medicine
Years later	Stored bone lead can return to the blood during pregnancy, breastfeeding, menopause, broken bones, long bed rest, kidney disease and older age.	ATSDR Case Studies in Environmental Medicine; CDC, Risk Factors and Pregnancy
Possibly lifelong	Some effects, such as on a child’s brain development and IQ, can be permanent.	CDC; NIEHS; WHO

So how long does lead poisoning last? No official source gives a single answer. A level built up over years comes down more slowly than one from a short exposure, because bone keeps releasing lead. In one study of retired lead workers cited by ATSDR, about half of the blood lead decline had a half-time of 13 years.

Lead stored in bone can come back

Because so much lead is stored in bone, a person can have lead in their blood long after the original source is gone. ATSDR calls this inert pool “a potential endogenous source of lead that can maintain BLLs long after exposure has ended.” Release increases with pregnancy, breastfeeding, menopause, advanced age, broken bones, being bedridden, kidney disease and some other conditions, and ATSDR says calcium deficiency makes it worse.

Pregnancy matters most here. The CDC says “the lead stored in the bones of adults can be released into the blood during pregnancy,” and WHO says this lead “becomes a source of exposure to the developing fetus.” If you are pregnant or planning a pregnancy and think you were exposed in the past, tell your health care provider.

This is also why a child’s level can rise again. ATSDR lists four reasons for a rising level: a source no one has found yet, abatement work that was not done properly, a known hazard that was not controlled, or lead stored in the child’s body moving back into the blood.

Which effects may be permanent, and what can improve

Official sources are direct about the permanent side. The CDC says “the effects of lead poisoning can be permanent and disabling” and that there are no safe levels of lead in the blood. WHO says lead “can permanently affect children’s brain development, resulting in reduced intelligence quotient (IQ),” along with shorter attention span and lower educational attainment, and that children who survive severe poisoning “may be left with permanent intellectual disability and behavioural disorders.”

What improves is the level of lead in the body. Stopping exposure prevents more damage, and that is the part families and health departments can control. For children, the CDC also points to services that help a child learn and develop, covered below; they support the child rather than undo effects.

Why removing the source is the most important step

A blood lead level cannot fall for long while new lead keeps coming in. That is why “finding and removing lead from the child’s environment” comes first in the CDC’s list of follow-up services, and why ATSDR tells doctors to start a prompt investigation for the source. Above the CDC reference value of 3.5 µg/dL, providers report the result to the health department, which may arrange a home investigation; the rules vary by state or city.

Common sources include deteriorating paint and the dust it makes in homes built before 1978, water from lead pipes, bare soil, lead brought home on work clothes, and some imported spices, remedies, cosmetics and pottery. See lead poisoning causes and prevention, or try our free home lead risk checker. Do not sand or scrape old paint yourself; that makes more lead dust.

Follow-up blood tests: how recovery is tracked

The only way to see recovery is repeat blood tests. For children, the CDC sets the timing by the confirmed (venous) level: early follow-up in 3 months for 3.5 to 9 µg/dL, 1 to 3 months for 10 to 19, 2 weeks to 1 month for 20 to 44, and as soon as possible for 45 or higher. Once levels are falling, the gaps get longer, up to 6 to 9 months. The full table is on our blood lead levels page.

Support for children: early intervention and school services

Because some effects can last, the CDC’s follow-up for children goes beyond the blood test. The CDC tells parents that a doctor “may also recommend connecting the child to early educational services.” Its guidance for providers says to check that the child is meeting developmental milestones and to refer families to supportive services as needed, such as developmental specialists and the Early Intervention Program.

A 2015 CDC expert panel report, Educational Interventions for Children Affected by Lead, notes there are no studies specifically on early educational interventions for lead-exposed children, but that children with or at high risk of developmental delays benefit most from interventions that start early. It calls for streamlined access to developmental assessment, intervention and special education services, and for consistent use of the Individuals with Disabilities Education Act (IDEA). Ask your child’s doctor about a developmental evaluation, and tell the school about the exposure. Our guide to lead and children has more on prevention and screening.

Nutrition: what the CDC says

The CDC’s wording on food is short. For children above the reference value, its follow-up services include “feeding the child a diet high in iron and calcium.” Its prevention advice for families says “a balanced diet with foods that provide calcium, iron, and vitamin C may help keep lead out of the body,” and notes that many of these foods can be bought through food assistance programs such as WIC.

A good diet supports the body; it does not remove stored lead and is not a treatment. Do not give supplements for lead unless your own or your child’s doctor tells you to.

Medical treatment at high levels

At very high blood lead levels, doctors may use chelation therapy, which the CDC describes as “a medical treatment used to remove lead from the body.” The CDC’s provider guidance places it at 45 µg/dL and above, decided with a medical toxicologist or a pediatrician experienced in lead poisoning, and ATSDR says chelation is not risk free. It lowers the lead load; it is not described by official sources as reversing damage already done. Our lead poisoning treatment guide explains the CDC’s actions at each level, and which doctor treats lead poisoning explains who to see.

Products sold online as lead “detox” or home chelation are not the same thing, and no official source we use recommends them.

Adults

Most adults with high blood lead were exposed at work, according to NIEHS, in jobs such as construction, mining, welding and battery manufacturing. Blood lead falls after exposure ends, more slowly after years of exposure. If you work with lead, tell your doctor.

Who to call

911 for severe symptoms such as a seizure, collapse or trouble breathing.
Poison Control, 1-800-222-1222, free and around the clock, if you think someone swallowed lead or you have urgent questions.
Your doctor or your child’s pediatrician for blood lead tests, follow-up and referrals.
Your local health department for case management and home investigations.

Frequently asked questions

Is lead poisoning reversible?

Partly. Blood lead levels come down once exposure stops, but lead stored in bone can stay for decades, and the CDC says some effects can be permanent. Stopping exposure early limits the harm.

Can you recover from lead poisoning?

Blood lead levels fall after the source is removed, tracked with repeat tests. Whether effects on learning or health improve varies; official sources describe some as permanent.

How long does lead poisoning last?

There is no single timeline. ATSDR estimates the half-life of lead in adult blood at about a month, but levels built up over years fall more slowly because bone keeps releasing lead. The CDC schedules children’s follow-up tests 2 weeks to 9 months apart depending on the level.

How long does lead stay in your body?

In the blood, weeks to months; in bone, years to decades. ATSDR gives an apparent half-time of one to two decades for lead in bone, and says part of it is stored for several decades.

Can lead come back years later?

Yes. ATSDR says bone lead can move back into the blood during pregnancy, breastfeeding, menopause, after a broken bone or with older age.

Lead Poisoning Lawyers and Lawsuits: What to Know Before You Call

If you or your child was exposed to lead, a lead poisoning lawyer can tell you whether someone else may be legally responsible: a landlord, a seller, a contractor, a product maker or a water system. Below: the common kinds of claims, the records that matter, deadlines, and how to find a lawyer or free legal aid.

Parent organizing medical and housing records at a kitchen table

This is general information, not legal advice. Every case depends on its facts and on the law of your state, and nothing here predicts an outcome or an amount. LeadDetector does not refer people to law firms and does not endorse any lawyer or firm. If a child has been exposed, the first call is to your doctor or local health department; Poison Control is 1-800-222-1222. Our lead poisoning hub covers the health side.

In short: lead poisoning lawsuits usually involve old housing with lead paint, renovation work done without lead-safe practices, contaminated products, or drinking water. Federal law lets buyers and renters of pre-1978 housing sue a seller, landlord or agent who knowingly fails to make the required lead disclosure, for three times their damages. The strongest cases rest on records: blood lead tests, inspection or risk assessment reports, health department files, disclosure forms and medical records. Deadlines to sue vary by state and often run differently for children, so talk to a lawyer early. A state or local bar referral service or LSC-funded legal aid can help you find one.

Common kinds of lead poisoning claims

Type of claim	Who may be responsible	Key records	Official source
Housing: missing lead disclosure	Seller, landlord, real estate agent, property manager of pre-1978 housing	Signed disclosure form (or its absence), lease or sales contract, pamphlet receipt, any lead reports	42 U.S.C. 4852d; EPA and HUD disclosure rule
Housing: lead hazards in a rental	Landlord or property owner, depending on state and local law	Inspection or risk assessment report, repair requests, photos, health department notices	State and local lead and housing laws
Renovation done unsafely	Contractor, renovation firm, landlord who hired them	Contract, Renovate Right pamphlet receipt, renovation records, dust test results	EPA RRP rule, 40 CFR 745 subpart E
Contaminated product	Manufacturer, importer, distributor, sometimes the seller	Product, packaging, lot numbers, receipts, recall notice, blood lead results	FDA and CPSC recall notices
Drinking water	Water system or government bodies, depending on the facts	Water test results, utility notices, address history, blood lead results	Court records and state attorney general releases
Workplace exposure	Usually handled through workers’ compensation; rules vary by state	Employer blood lead monitoring results, medical records, job history	OSHA lead standards; state workers’ compensation offices

Landlords, sellers and the federal disclosure rule

Before most pre-1978 homes are sold or leased, the seller or landlord must disclose known lead-based paint and hazards, hand over any reports, give the EPA pamphlet and include a Lead Warning Statement. Our lead paint disclosure guide covers the details and exemptions.

The law behind that rule, 42 U.S.C. 4852d, gives buyers and renters a private right to sue. A person who “knowingly violates” it is jointly and severally liable to the purchaser or lessee for three times the damages they incurred, and a court may award court costs plus attorney and expert witness fees to a prevailing plaintiff. Separately, EPA and HUD can seek civil penalties; the current inflation-adjusted maximum listed in 40 CFR 19.4 and 24 CFR 30.65 is $22,263 per violation.

Two limits are worth knowing. The rule requires disclosure, not testing or removal, so a landlord who honestly knew nothing may not have broken it. And “knowingly” matters: the treble damages provision applies to knowing violations. Many states and cities add their own rental lead laws.

Contractors and the RRP rule

Paid work that disturbs paint in pre-1978 homes, child care facilities and preschools must be done by EPA-certified firms using lead-safe practices such as containment and a final cleaning check. The firm must give occupants the Renovate Right pamphlet before work and provide records of compliance afterward. EPA enforces the rule, and the maximum civil penalty under the Toxic Substances Control Act is currently listed at $49,772 per violation. If dust from careless work exposed your family, the contract, the pamphlet acknowledgment, the renovation records and any dust test results are key evidence. See lead-safe renovation and the RRP rule.

Contaminated products: the cinnamon applesauce pouches

The best-known recent product example is the 2023 recall of cinnamon applesauce pouches. FDA reports that WanaBana apple cinnamon fruit puree pouches were recalled in late October 2023, with Schnucks and Weis cinnamon applesauce pouches added on November 9, 2023. FDA traced the lead to cinnamon from Ecuador supplied through Negasmart to the manufacturer Austrofoods, and later sent warning letters to Austrofoods and Dollar Tree. As of March 22, 2024, CDC counted 136 confirmed, 345 probable and 38 suspected cases in 44 states, DC and Puerto Rico.

Federal court dockets show product liability suits against WanaBana starting October 31, 2023 in North Carolina, followed by cases in Florida, New York, Illinois, Texas and other districts, including suits filed on behalf of children. On May 24, 2024, WanaBana LLC and WanaBana USA LLC each filed Chapter 7 bankruptcy cases in Delaware. We have not confirmed how individual cases were resolved, so we don’t describe outcomes. If you think a product exposed your family, keep the product and packaging and check our lead product recall search.

Drinking water: the Flint settlement

Water cases are often large, consolidated cases against public bodies. In the Flint water cases, the settlement agreement called for the State of Michigan defendants to pay $600 million and the City of Flint defendants $20 million, with other defendants adding smaller amounts. Judge Judith E. Levy of the US District Court for the Eastern District of Michigan granted final approval on November 10, 2021. It covers minors, adults, property owners and businesses, with separate funds for each group.

Workplace exposure

Claims for work-related illness typically go through state workers’ compensation programs; the US Department of Labor links to every state’s workers’ compensation office. OSHA’s lead standards (29 CFR 1910.1025 for general industry and 1926.62 for construction) require employers to offer blood lead monitoring to workers exposed at or above the action level, to remove workers with high blood lead levels from exposure while keeping their earnings, seniority and benefits for up to 18 months, and to give workers their medical and monitoring records on request.

What evidence matters in a lead case

A case connects the lead source, the exposure and the harm. Gather and copy these:

Blood lead test results. CDC says a finger-prick or heel-prick test is often the first step and a venous blood draw is used to confirm; ask for written results with dates. See our blood lead test guide.
Inspection or risk assessment reports. A certified inspection shows where lead-based paint is; a risk assessment shows current hazards like peeling paint and lead dust. See lead paint inspection.
Health department records. CDC guidance calls for elevated results to be reported to the health department and, as required locally, an environmental investigation of the home. Ask for copies of any notices, orders or reports.
Disclosure forms, leases and contracts. The signed lead disclosure (or proof you never got one), renovation contracts and pamphlet receipts.
Photos and dated messages. Peeling paint, dust after work, repair requests to the landlord and their replies.
Medical and school records. Doctor visits, developmental evaluations and educational services.
The product itself, with packaging, lot numbers and receipts, for product cases.

Deadlines: statutes of limitations

Deadlines to sue differ by state and type of claim, and many states treat children’s claims differently. Because a missed deadline can end a claim no matter how strong it is, ask a lawyer about yours early.

One example, Maryland only: Maryland’s general rule (Courts and Judicial Proceedings 5-101) is that a civil action must be filed within three years of when it accrues, unless another law sets a different period. Under section 5-201, when a claim belongs to a minor, the person has the lesser of three years or the applicable period to file after the disability ends. This is one state’s general rule, shown only as an example; exceptions may apply, and other states differ.

How to find a lead poisoning attorney

Bar lawyer referral services. Many state and local bar associations run referral services that match you with a lawyer in the right practice area. The American Bar Association keeps a lawyer referral directory searchable by city and state.
Free legal aid. The Legal Services Corporation funds 129 independent nonprofit legal aid organizations across the US and territories. Its I Need Legal Help page finds the one near you, and it points to LawHelp.org for free legal information and forms.
Check the lawyer. The State Bar of California, for example, says to look up a lawyer’s license and discipline history on the bar’s website, and to be wary of lawyers who solicit you in person or by phone.

Questions to ask, and how contingency fees work

Many injury lawyers work on contingency. The FTC explains that this means you pay the lawyer a percentage of the money you get if you win, that you may also pay case expenses such as depositions, expert witnesses and filing fees, that there is no standard percentage, and that you can negotiate it. Get the fee agreement in writing. Questions the FTC suggests include:

What is your experience with my kind of case?
What are the chances of getting the solution I want?
What are the fees for each person who will work on my case, and how will I be billed?

Also ask whether expenses come out before or after the lawyer’s percentage, and who pays them if you lose. Keep all documents and messages from your lawyer, as the California bar advises, and avoid paying in cash.

Fair housing protections for families with children

Lead paint is not a legal reason to turn away families with children. The federal Fair Housing Act bars refusing to rent because of familial status, and the US Department of Justice has sued landlords over exactly this: in United States v. Sawicki (D. Mass., 2001), the complaint alleged a landlord refused to rent to a mother because her child was under six and the apartments contained lead paint. HUD’s fair housing rules (24 CFR 100.400) also prohibit retaliating against someone for filing a fair housing complaint or reporting a discriminatory housing practice. Protection against retaliation for other complaints, such as repair or code complaints, comes from state or local law where it exists, so ask a local legal aid office or lawyer.

Lead poisoning lawsuit questions

Can I sue my landlord for lead poisoning?

Possibly. Federal law allows renters to sue a landlord who knowingly failed to make the required lead disclosure for pre-1978 housing, for three times their damages. Other claims depend on state and local law. A local lawyer or legal aid office can tell you what applies.

How much is a lead poisoning settlement worth?

No one can say without the facts, and we don’t estimate amounts. Be cautious of anyone who promises a figure.

Is there a lead poisoning class action I can join?

Some lead cases, like the Flint water cases, have been handled as class actions or consolidated cases, while many others are individual suits. A lawyer can check whether any pending case covers you.

How long do I have to file a lead poisoning lawsuit?

It depends on your state and the type of claim, and children’s claims often follow different rules. Don’t wait: ask a lawyer as soon as you can.

Does LeadDetector recommend lawyers?

No. LeadDetector does not refer people to law firms or endorse any lawyer. We point you to bar referral services and legal aid so you can choose.

Lead Poisoning in Adults: Symptoms, Signs and When to Get Tested

Lead poisoning in adults most often shows up as vague, everyday complaints: headaches, tiredness, joint and muscle pain, stomach pain or constipation, trouble concentrating or remembering, mood changes and higher blood pressure. Many adults with lead in their blood have no symptoms at all, which is why the CDC and its toxic substances agency, ATSDR, say a blood lead test is the way to know.

Nurse checking an adult's blood pressure in a clinic

In short: lead affects almost every system in an adult’s body. Official sources link it to high blood pressure, nervous system problems (headache, fatigue, poor concentration, memory loss, depression and irritability, tingling in the hands or feet), joint and muscle pain, stomach pain, kidney damage, anemia, and fertility problems in men and women, including lower sperm counts and abnormal sperm. In pregnancy, lead is linked to miscarriage and to babies born too early or too small. At very high levels lead can injure the brain (encephalopathy) and cause seizures, coma and death. Symptoms alone cannot tell you whether lead is the cause; a blood lead test ordered by a health care provider can. For urgent questions call Poison Control at 1-800-222-1222, and call 911 for severe symptoms such as seizures.

This page explains what the CDC, NIOSH, ATSDR, NIEHS, OSHA, WHO and MedlinePlus say about lead poisoning symptoms in adults. It is not medical advice. Only a health care provider can decide what your symptoms mean and what to do next. For symptoms in children, see our main lead poisoning symptoms guide; for the bigger picture, start at lead poisoning.

Common signs of lead poisoning in adults

Adults absorb less of the lead they swallow than young children do, the WHO notes, and ATSDR says adults show nervous system symptoms at higher blood lead levels than children. But lead builds up over months and years, mostly in bone, and the signs tend to creep in slowly. Here is what official sources list, grouped the way you might notice them:

High blood pressure. NIOSH lists increased blood pressure among the effects of long-term exposure, the WHO names a higher risk of high blood pressure as a long-term harm in adults, and NIEHS says blood lead levels below 10 µg/dL are associated with increases in blood pressure and hypertension.
Joint and muscle pain. ATSDR lists muscle aches at low exposure and joint pain (arthralgia) at moderate exposure. OSHA says workers above 40 µg/dL begin to have joint pain and muscle pain (myalgia).
Headaches and fatigue. Headache, exhaustion and weakness are on NIOSH’s list for high short-term exposure; ATSDR lists mild fatigue at low exposure and general fatigue and headache at moderate exposure; OSHA adds sleep disturbance.
Stomach pain and constipation. NIOSH lists stomach pain, nausea and constipation for long-term exposure, and MedlinePlus says stomach pain and cramping are usually the first sign of a high, toxic dose. ATSDR notes that severe cramping (lead colic) can be mistaken for appendicitis.
Memory and concentration problems. NIOSH lists memory loss, distraction and forgetfulness. ATSDR lists difficulty concentrating, and in lead-exposed workers impaired concentration, slower reaction time and reduced hand dexterity.
Mood changes. NIOSH names depression, irritability and altered moods or behavior; ATSDR adds increased nervousness and lethargy.
Tingling or pain in the hands and feet. NIOSH lists pain or tingling in the hands or feet. ATSDR describes slowed nerve conduction and wrist weakness (“wrist drop”) as late signs in workers with long, high exposure.
Fertility problems. NIOSH lists fertility problems in men and women. ATSDR says occupational exposure may lower total sperm counts and increase abnormal sperm, and NIEHS links blood lead above 15 µg/dL to lower sperm counts and motility and to delayed conception. ATSDR also lists decreased libido and impotence among symptoms in exposed workers.
Pregnancy loss and early birth. The CDC says lead in a pregnant person’s blood raises the risk of miscarriage and of a baby being born too early or too small; the WHO says lead exposure in pregnancy can cause reduced fetal growth and preterm birth.

Some effects cause no symptoms you would notice. Kidney damage and anemia, for example, usually show up only in blood and urine tests. ATSDR adds that lead-induced anemia in adults is not common and appears only when blood lead has been high for a long time.

Lead toxicity in adults, system by system

ATSDR’s course for clinicians says lead serves no useful purpose in the body and can affect every organ system. This table sums up what each agency lists for adults.

Body system	Symptoms or effects in adults	Source
Heart and blood vessels	Increased blood pressure and hypertension; possible links to heart disease and stroke	NIOSH, NIEHS, WHO, ATSDR
Brain and nerves	Headache, fatigue, memory loss, forgetfulness, difficulty concentrating, tremor, tingling or pain in hands and feet; at very high levels encephalopathy, seizures, coma	NIOSH, ATSDR, OSHA, MedlinePlus
Mood and behavior	Depression, irritability, altered moods, nervousness, lethargy	NIOSH, ATSDR
Muscles and joints	Muscle aches (myalgia), joint pain (arthralgia), weakness	ATSDR, OSHA, NIOSH
Digestive system	Stomach pain, nausea, vomiting, constipation, loss of appetite, weight loss, metallic taste; severe cramping (colic) at high levels	NIOSH, ATSDR, MedlinePlus
Kidneys	Decreased kidney function, kidney damage	NIEHS, WHO, NIOSH
Blood	Anemia (uncommon in adults; seen with long, high exposure)	ATSDR, NIOSH, WHO
Male reproduction	Lower sperm counts, abnormal sperm, reduced motility; decreased libido, impotence	ATSDR, NIEHS, OSHA
Female reproduction and pregnancy	Delayed conception; miscarriage; baby born too early or too small	NIEHS, ATSDR, CDC, WHO
Other	Decreased lung function, bone or tooth loss, more infections	NIOSH

For how these effects play out over years, and which ones can last, see effects of lead poisoning.

How symptoms change with the level of exposure

ATSDR describes a “continuum” of signs and symptoms that tend to grow as exposure grows. It stresses that this is only a guide: symptoms vary from person to person, and no exact blood lead number can be attached to each stage.

Lowest exposure: the person may seem to have no symptoms, while subtle effects on thinking, learning and memory are possible.
Low exposure: irritability, lethargy, mild fatigue, muscle aches or tingling, occasional stomach discomfort.
Moderate exposure: joint pain, constipation, difficulty concentrating and muscles that tire easily, stomach pain, general fatigue, headache, tremor, vomiting, weight loss.
High exposure: intermittent severe stomach cramps (colic); encephalopathy that can quickly lead to seizures, a change in consciousness, coma and death; weakness or paralysis.

ATSDR says symptomatic lead poisoning in adults generally comes with blood lead levels of 40 to 60 µg/dL, and severe toxicity is often seen at 100 µg/dL or more. OSHA’s health-effects page for workers gives a similar picture:

Adult blood lead level	What OSHA says is associated
As low as 10 µg/dL (chronic exposure)	Impaired kidney function, high blood pressure, nervous system and behavioral effects, cognitive decline later in life
Above 20 µg/dL	Subtle effects on thinking; effects on sperm and semen quality; delayed conception
20 to 40 µg/dL	Cognitive aging, poorer hand-eye coordination, slower reactions, attention problems
Above 40 µg/dL	Symptoms begin: headache, fatigue, sleep disturbance, joint pain, muscle pain, loss of appetite, constipation
Above 60 µg/dL (much less common today)	Convulsions, coma and in some cases death; anemia, nerve damage, kidney scarring, severe stomach cramps

The point to take from both sources: by the time an adult feels clearly unwell from lead, blood lead is usually well above the levels where quieter harm, such as rising blood pressure or reduced kidney function, has already been found. Our blood lead levels guide explains what the numbers mean.

Why symptoms are often vague or missing

NIOSH says lead symptoms are similar to those of other illnesses, may develop slowly and can be overlooked. ATSDR notes that many people with lead poisoning have no symptoms, and that lead is often missed or misdiagnosed because tiredness, headaches, stomach pain and high blood pressure have so many other causes.

The NIEHS adds that health effects in adults have been found at blood lead levels below 5 µg/dL, such as decreased kidney function, and the WHO says there is no known safe blood lead concentration. In other words, feeling fine does not mean lead is doing nothing, and feeling unwell does not mean lead is the cause.

Very high levels: encephalopathy and seizures

Severe lead poisoning is rare in US adults today, but it still happens, mostly through work or contaminated products. MedlinePlus lists the signs of very high lead levels as vomiting, internal bleeding, a staggering walk, muscle weakness, seizures and coma. ATSDR describes lead encephalopathy (swelling and injury of the brain) as able to progress suddenly to seizures, coma and death, and says warning signs that can come first include dullness, irritability, memory loss, muscle tremor and a poor attention span.

These are emergencies. MedlinePlus says to call 911 right away for severe symptoms such as vomiting or seizures.

Where adults are exposed to lead

The NIEHS says most adults with elevated blood lead were exposed at work. The main sources, briefly:

Jobs: renovation, painting and demolition of older buildings, bridge and steel-structure work, battery making and recycling, smelting and foundries, welding and cutting, mining, firing ranges, radiator repair.
Hobbies: casting bullets or fishing weights, target shooting, stained glass, lead glazes and pigments.
Home renovation in a house built before 1978, when lead paint was still sold for homes.
Imported products: some traditional or Ayurvedic remedies, cosmetics such as kohl, and recalled spices, including cinnamon.
Drinking water from lead service lines, lead solder or older brass fixtures.

NIOSH also warns that workers can carry lead dust home on clothes, shoes and hair, putting children and pregnant family members at risk. Our guide to lead testing for adults covers each of these in detail, including what OSHA requires employers to provide.

Symptoms are not a diagnosis: a blood lead test is

No list of symptoms can confirm or rule out lead poisoning. The CDC calls a blood lead test the best way to assess a person’s exposure, and ATSDR tells clinicians that lead can only be diagnosed early if they suspect it behind common, nonspecific complaints. The test uses a blood sample drawn by a health care provider and sent to a laboratory. Home swab kits test surfaces like paint, not people.

If you have symptoms on this page and a possible source of lead, tell your doctor about your job, hobbies, home and any imported remedies, cosmetics or spices, and ask whether a blood lead test makes sense. Our lead poisoning test guide explains how the test works.

When to call a doctor, Poison Control or 911

Situation	Who to call
Seizures, repeated vomiting, collapse or trouble breathing	911 right away
Symptoms you think may be from lead, or you swallowed or breathed something that may contain a lot of lead	Poison Control, 1-800-222-1222 (free and confidential, 24/7)
Vague symptoms and a possible ongoing source (work, hobby, renovation, remedy, water)	Your health care provider or local health department, to ask about a blood lead test
You work with lead	Your employer’s medical program and your own doctor; tell your family’s doctors too
You are pregnant or planning a pregnancy and may be exposed	Your prenatal care provider

MedlinePlus notes that for suspected low-level exposure an emergency room visit is usually not needed unless the exposure was a high dose.

What happens after a high result

Treatment is a medical decision: your doctor decides, often with the local health department or a medical toxicologist. The first step official sources describe is always the same, finding the source and stopping the exposure. Do not try supplements, “detox” products or anything sold to remove lead from the body. Our lead poisoning treatment page explains what doctors consider, lead poisoning recovery covers what to expect afterwards, and lead poisoning statistics has the national numbers.

Frequently asked questions

What are the first signs of lead poisoning in adults?

Often there are none. When symptoms appear, ATSDR lists irritability, tiredness, muscle aches or tingling and occasional stomach discomfort among the earliest. MedlinePlus says stomach pain and cramping are usually the first sign of a high, toxic dose.

Can lead poisoning cause high blood pressure?

Yes. NIOSH, NIEHS, ATSDR and the WHO all link lead to higher blood pressure in adults, and NIEHS says the association is seen at blood lead levels below 10 µg/dL. High blood pressure has many causes, so only testing can show whether lead plays a part.

Can lead affect fertility in men and women?

Yes. ATSDR says occupational exposure may lower sperm counts and increase abnormal sperm, and NIEHS links blood lead above 15 µg/dL to lower sperm counts and motility and to delayed conception. In pregnancy, the CDC links lead to miscarriage and to babies born too early or too small.

Can I have lead poisoning without symptoms?

Yes. ATSDR says many people with lead poisoning have no symptoms, and NIEHS reports effects such as decreased kidney function at low levels. A blood lead test is the only way to know.

Is lead poisoning in adults the same as lead toxicity?

The terms are used interchangeably. ATSDR’s clinician course is titled “Lead Toxicity,” and it covers the same symptoms and effects described on this page.

Lead Testing for Adults: Who Should Get a Blood Lead Test

The lead poisoning test for adults is the same as for children: a blood lead test, ordered by a health care provider or done through your employer’s medical program. The CDC says it is the only way to tell whether you have been exposed, and most exposed adults have no symptoms. What matters is whether your work, hobby or home puts you near lead.

Pregnant woman talking with her doctor in a calm clinic room

In short: adults who work with lead (construction and renovation, battery making and recycling, smelting, firing ranges, welding and cutting, demolition), adults with lead hobbies (shooting, casting bullets or fishing weights, stained glass, lead glazes), and adults who use certain imported remedies, cosmetics or spices should talk to a doctor about a blood lead test. At work, OSHA requires employers to offer free blood lead testing to workers exposed at or above an airborne action level of 30 µg/m³. The CDC does not recommend testing every pregnant woman, but it does recommend a risk assessment at the first prenatal visit and a blood test if even one risk factor is found.

This guide explains what the CDC, NIOSH and OSHA say. It is not medical advice: only a health care provider can decide whether you need a test and what your result means. For urgent questions about a possible poisoning, call Poison Control at 1-800-222-1222.

Which adults should ask about a blood lead test

Most adult lead exposure comes from work. The CDC’s list of jobs that may involve lead includes:

Repair, renovation, remodeling and painting of homes and commercial buildings, plus abatement and demolition
Painting or sanding steel structures such as bridges and water towers
Making products that contain lead, such as batteries, bullets and circuits, and recycling materials such as electronics (NIOSH also names lead-acid battery recycling)
Melting lead: secondary smelting, foundries and casting, incinerators; and mining or smelting ore
Using firearms or working at a firing range (law enforcement, military, instructors)
Welding and cutting, and art work with leaded ceramic glaze, glasswork or stained glass

NIOSH studies have also found lead exposure above OSHA’s limit in radiator repair shops.

Hobbies count too. The CDC names casting or soldering (bullets, fishing weights, stained glass), target shooting, mixing or applying lead glazes and pigments, home renovation in a building from before 1978, and drinking home-distilled liquor such as moonshine. People with bullet fragments retained from a gunshot wound are also on the CDC’s list.

Finally, some products carry lead into the body directly. The CDC lists complementary, alternative or traditional medicines, cosmetics and ceremonial powders that may contain lead; the FDA has warned about kohl (also sold as kajal, surma and other names) and about certain Ayurvedic products; and recalls have involved ground spices, including cinnamon. Our guide to lead in cinnamon and spices covers the food side, and lead poisoning causes and prevention covers the rest.

Who is recommended a test: a quick table

Your situation	What’s recommended	Source
Worker exposed to airborne lead at or above 30 µg/m³ (the action level)	The employer must offer blood lead testing (and zinc protoporphyrin) at no cost; periodic testing follows	OSHA 29 CFR 1910.1025 and 1926.62
Construction worker exposed at or above the action level on any day	Initial blood sampling offered by the employer	OSHA 29 CFR 1926.62(j)(1)(i)
Worker whose employer does not test	Ask your employer about routine testing; if there is none, talk with your health care provider	CDC/NIOSH Information for Workers

Use of imported remedies, kohl or similar cosmetics	Stop using the product; ask a provider about testing, especially for children and pregnant or nursing women	FDA (kohl); CDC
Pregnant, with one or more risk factors	Blood lead test; risk assessment at the earliest prenatal contact	CDC 2010 pregnancy guidelines
Breastfeeding parent who works with lead	Also ask the baby’s pediatrician whether you should have a blood lead test	CDC/NIOSH Information for Workers

Lead exposure at work: what the OSHA lead standards require

Occupational lead exposure in the US is covered by two OSHA standards: 29 CFR 1910.1025 for general industry and 29 CFR 1926.62 for construction. Both set a permissible exposure limit (PEL) of 50 µg/m³ of air and an action level of 30 µg/m³, each averaged over an 8-hour day. The action level is what switches on the blood testing rules. Blood levels below are in µg/dL, as on a lab report.

Blood testing schedule

General industry: workers exposed at or above the action level for more than 30 days a year get blood lead testing at least every 6 months; every 2 months if the last result was 40 µg/dL or higher (until two results in a row are below 40); and at least monthly while removed from lead work.
Construction: initial blood sampling for anyone exposed at or above the action level on any day. Workers exposed at that level for more than 30 days in any 12 months are tested at least every 2 months for the first 6 months, then every 6 months; every 2 months while at 40 µg/dL or higher; monthly during removal.
In construction, tasks such as manual scraping or sanding of lead paint and heat-gun use count as high exposure until measured, with blood monitoring as part of interim protection.

Both standards say the medical surveillance must be provided without cost to employees. In construction, the employer must tell each worker their blood lead result in writing within five working days. In both, workers at 40 µg/dL or higher must be told in writing within five working days, along with the medical removal rules.

Medical removal

	General industry (1910.1025)	Construction (1926.62)
Removed from lead exposure at	60 µg/dL or higher, or an average of the last three tests at 50 µg/dL or higher (not required if the last test was below 40)	50 µg/dL or higher
Return to former job	Two tests in a row below 40 µg/dL	Two tests in a row below 40 µg/dL
Medical removal protection	Up to 18 months of benefits (pay, seniority and rights kept)	Up to 18 months of benefits

Workers also have a right to a second medical opinion, and under the general industry standard a worker can ask for pregnancy testing or a male fertility evaluation as part of the medical exam.

Keep in mind that these numbers date from the 1970s and 1990s. OSHA itself said in 2022, when it opened a rulemaking on the blood lead triggers, that harm in adults can occur below the current removal and return-to-work levels. As of October 2026 OSHA’s page still shows only that 2022 advance notice, with no proposed rule. NIOSH notes that a few state agencies, such as Michigan’s MIOSHA and the California Department of Public Health, have their own blood lead guidance for workers, so check your state. For what health research says about lower levels, see effects of lead poisoning and blood lead levels.

Take-home lead: protecting your family

NIOSH warns that people who work near lead can bring lead dust home on their clothes, shoes and hair, and that children and pregnant women are especially at risk. NIOSH’s advice to workers:

Change into work clothes and shoes that stay at work, and never leave without cleaning up, even for a quick trip.
Wash with soap designed to remove lead before eating, drinking or smoking; NIOSH says ordinary soap and water are not enough.
Shower and wash your hair before leaving if showers are provided; if not, wash as much skin as you can and change clothes and shoes before going home.
Do not take tools, scrap or packaging home. If work clothes must go home, keep them in a closed plastic bag and wash and dry them alone.

For workers above the PEL, OSHA’s construction standard also requires clean change areas and showers where feasible. If someone in your home works with lead, ask your children’s doctor about testing them; our blood lead test guide explains how it works for children. Home renovators should follow lead-safe renovation (RRP) practices.

Lead test in pregnancy and while breastfeeding

Lead stored in bone can be released during pregnancy and pass to the baby, the CDC says. Its Guidelines for the Identification and Management of Lead Exposure in Pregnant and Lactating Women (November 2010, still linked from CDC’s pregnancy page) say:

The CDC does not recommend testing all pregnant women. Routine testing is recommended in clinics that serve populations with specific risk factors.
Elsewhere, providers should assess risk as part of the occupational, environmental and lifestyle history, at the earliest prenatal contact, and test if even one risk factor is found.
Risk factors named include recent immigration, pica (eating non-food items), work with lead, nutritional status, traditional remedies or imported cosmetics, and lead-glazed pottery used for cooking or storing food. Old paint matters mainly during renovation of older homes.
Follow-up testing and a search for the source start at 5 µg/dL. The guidelines say pregnant women at 10 µg/dL or higher should be removed from work exposure to lead.
Breastfeeding: the CDC encourages mothers below 40 µg/dL to breastfeed, and encourages mothers at 40 µg/dL or higher to pump and discard milk until their level drops below 40. CDC’s breastfeeding page says testing breast milk for lead is not recommended.

The American College of Obstetricians and Gynecologists (ACOG) Committee Opinion No. 533 on lead screening in pregnancy also favors a risk assessment over routine testing for everyone. If any of these risk factors apply, tell your provider. Treatment decisions belong to your doctor; do not try supplements or products sold to “remove lead.”

Adult lead surveillance: NIOSH ABLES and your state

NIOSH runs the Adult Blood Lead Epidemiology and Surveillance program (ABLES), which it describes as a state-based surveillance program of laboratory-reported adult blood lead levels. Labs report adult results to participating states, which follow up on high results and track where exposure comes from. Since 2015, NIOSH has used 5 µg/dL as the reference level that marks an elevated adult blood lead level for surveillance. The Council of State and Territorial Epidemiologists (CSTE) uses a reference value of 3.5 µg/dL for adults and children.

How to ask your doctor or employer

Your employer: NIOSH suggests asking whether they do routine blood lead testing and following their lead control plan. If you are exposed at or above the action level, OSHA requires the employer to offer testing at no cost.
Your doctor: say plainly what you do: “I scrape paint in old houses,” “I cast my own bullets,” “I use an imported remedy.” NIOSH says lead symptoms look like other illnesses, so your exposure history is what prompts the test.
Concerns about your workplace: NIOSH offers a free Health Hazard Evaluation on request, and you can contact your nearest OSHA office about unsafe conditions.

Cost and coverage

For workers covered by OSHA’s lead standards, required blood testing is free to the employee. Outside work, the CDC says health care providers and most local health departments can test for lead, and many private insurance plans cover the test. We do not list prices because no official source publishes one; ask your provider, insurer or health department before the test.

Home test kits do not test people. They check paint, dust, soil or water, which helps find a source but cannot replace a blood test. See our lead poisoning test page and the lead poisoning hub.

Frequently asked questions

Is there a lead poisoning test for adults?

Yes. It is a blood lead test, usually a blood draw from a vein, ordered by a health care provider or done through an employer’s medical surveillance program. The CDC says it is the only way to confirm exposure.

Does my employer have to pay for a blood lead test?

If you are exposed at or above OSHA’s action level of 30 µg/m³, the lead standards require the employer to provide medical surveillance, including blood lead tests, without cost to you.

Should every pregnant woman get a lead test?

The CDC does not recommend testing all pregnant women. It recommends a risk assessment at the first prenatal contact and a blood lead test if any risk factor is found, and routine testing where the patient population has known risk factors.

Heavy Metal Test: Blood, Urine and Hair Tests Explained

A heavy metal test measures possibly harmful metals such as lead, mercury, arsenic and cadmium in a sample of blood or urine, and less often hair or nails. Which sample is right depends on the metal: for lead, the CDC and ATSDR point to a venous blood test, while urine is the usual sample for arsenic and for some forms of mercury.

Urine sample cup and blood tubes side by side on a lab tray

In short: a “heavy metal panel” usually checks lead, mercury, arsenic and cadmium together. For lead, a blood test is the standard; a lead in urine test is mainly a specialist tool. Arsenic and inorganic mercury are better measured in urine. Hair testing for lead is not recommended by ATSDR, because hair picks up lead from the outside. “Provoked” urine tests taken after a chelating drug are not scientifically validated, according to the American College of Medical Toxicology. The safest route is to ask your doctor to order the test from an accredited lab.

This guide summarizes official and clinical sources. It is not medical advice: only a health care provider can decide which test you need and what a result means. For urgent questions about a possible poisoning, call Poison Control at 1-800-222-1222.

What a heavy metal panel usually measures

MedlinePlus, the National Library of Medicine’s health site, describes heavy metal testing as a group of tests that measure possibly harmful metals in the body. The metals most often tested are lead, mercury, arsenic and cadmium, with chromium sometimes added. A doctor can order a single metal or a group of them, called a heavy metal panel. Blood and urine are the samples used most often.

Large reference laboratories list what their panels include, and the core four are the same:

Blood panel: Mayo Clinic Laboratories’ Heavy Metals Screen, Blood (test ID HMDB) measures arsenic, cadmium, lead and mercury in whole blood.
Urine panel: ARUP Laboratories’ Heavy Metals Panel 4, Urine measures arsenic, cadmium, mercury and lead in a 24-hour or random urine sample. Other ARUP panels drop cadmium or add copper and zinc.

Which sample fits which metal

Each metal behaves differently, so labs and ATSDR (the federal Agency for Toxic Substances and Disease Registry) use different samples for different metals.

Test	Sample	Good for	Limits
Blood lead test	Venous blood (blood draw from a vein); finger-stick for screening	Recent or ongoing lead exposure; the standard lead test per CDC and ATSDR	Shows mainly recent exposure, not where the lead came from; a high finger-stick result needs a venous confirmation
Heavy metal blood panel	Whole blood	Lead, mercury, cadmium and arsenic in one draw	Blood arsenic shows only very recent exposure; labs prefer urine for arsenic
Heavy metal urine panel	24-hour or random urine	Arsenic, inorganic and metallic mercury, cadmium	Seafood can raise arsenic; contamination can give false highs; contrast dye in the last 72 hours makes the sample unusable
Lead in urine test	24-hour or random urine	Specialist uses, such as chronic exposure or monitoring treatment	ARUP says venous blood lead is the preferred routine test
Hair or nail test	Hair cut near the scalp, nail clippings	Methylmercury (hair), past high arsenic exposure	ATSDR says hair lead is not recommended; outside contamination, no agreed reference ranges
“Provoked” or “challenge” urine test	Urine collected after a chelating drug	Nothing validated	ACMT recommends against it; no reference values, and chelators raise metals in anyone’s urine

Lead: blood first

The CDC calls a blood lead test the best way to find out whether a child has lead poisoning. ATSDR’s clinical guidance for doctors says venous blood lead testing is the most useful screening and diagnostic test for recent or ongoing lead exposure. The CDC’s blood lead reference value for children is 3.5 µg/dL. Our blood lead test guide explains finger-stick versus venous samples, and blood lead levels covers what the numbers mean.

Arsenic: urine

ATSDR says the urine test is the most reliable test for arsenic exposure within the last few days. ARUP Laboratories lists blood arsenic only for recent (under 24 hours) or large-dose exposure, and calls its urine arsenic test the preferred test for both acute and chronic exposure. Seafood can raise urine arsenic, so ARUP asks patients to avoid shellfish and seafood for 48 to 72 hours before collection. If total arsenic is high, the lab can split the result into its forms, separating the toxic inorganic kinds from harmless organic ones.

Mercury: depends on the form

ATSDR explains that urine mercury is used for exposure to metallic mercury vapor and inorganic mercury, while whole blood or scalp hair is used to monitor methylmercury, the form found in fish. Urine is not useful for methylmercury.

Cadmium: blood or urine

ARUP’s directory lists urine cadmium for chronic exposure and body burden, and blood cadmium for acute (recent) exposure.

The lead in urine test: when it is used

A lead in urine test is not the main lead test. ARUP Laboratories says a urine lead test may be useful for assessing chronic lead exposure or for monitoring chelation therapy, and that for routine testing of lead exposure a venous blood lead test is preferred. ATSDR’s toxicological profile for lead also describes blood as the common measure of absorbed lead.

ARUP also warns that high urine results may come from skin or collection contamination and should be confirmed with a second specimen. A lead in urine result is for a doctor to read alongside a blood test, not a stand-alone answer.

Why “provoked” urine tests are not recommended

Some practitioners offer a “provoked,” “challenge” or “post-chelator” urine test: the patient takes a chelating drug such as DMSA or DMPS, which binds metals, and then collects urine. The results often look alarming. The American College of Medical Toxicology (ACMT), the specialty society for doctors who treat poisonings, has recommended against this test since 2010 and repeated the position in 2017.

In its 2017 statement in the Journal of Medical Toxicology, ACMT says post-chelator testing has not been scientifically validated, has no demonstrated benefit and may be harmful. There are no accepted normal reference values for urine collected after a chelator, and chelators raise urine metals in healthy people as well as poisoned ones, so a “high” result does not show poisoning. ACMT warns the test can lead to unnecessary, costly and sometimes harmful treatment, and cites deaths after improper use of chelating agents.

Chelation itself is a medical treatment, not a test and not a detox. The FDA says every FDA-approved chelation product requires a prescription, and that it has never approved any chelation product for over-the-counter use. Whether anyone needs chelation is decided only by a doctor. Our lead poisoning treatment page explains what official guidance describes.

Hair test for lead: what CDC and ATSDR say

Hair analysis is painless and widely sold online, but federal health agencies do not support it for lead:

ATSDR’s lead course for clinicians (on the CDC site) says that because hair and fingernails are exposed to outside contamination, testing their lead content gives an uncertain estimate of body burden and is not recommended. It cites the CDC and the American Academy of Pediatrics.
An ATSDR expert panel on hair analysis (2001) found that metals on hair are hard to separate into what came from inside the body and what landed on it from dust, air or hair products. It also noted a lack of agreed reference ranges, and found an established link between hair levels and health outcomes only for methylmercury.
ATSDR’s arsenic fact sheet says hair and nail tests can show high arsenic exposure over the past 6 to 12 months, but cannot predict whether the levels will affect your health.

At-home heavy metal test kits

Heavy metal kits sold online usually ask you to mail hair, urine or a few drops of finger-prick blood to a lab. We do not name or recommend any of them, for two reasons, besides the hair problem above:

The FDA has warned about some. In its questions and answers on unapproved chelation products, the FDA says companies selling over-the-counter chelation products have also marketed heavy metal urine tests, that these kits are not cleared by the FDA and that they may give false or misleading results.
Collection matters. Labs use trace-element-free containers, and the CDC warns that lead on the skin can get into a finger-prick sample and read falsely high.

Under federal CLIA rules (run by CMS), any lab testing human samples to assess health must hold a CLIA certificate, so if you consider a kit, ask whether the lab is CLIA-certified and which sample it uses for each metal. Even then, a doctor will want a confirmed blood test before acting on a lead result. Home swab and water kits, by contrast, test surfaces and water, not people; see our lead poisoning test guide.

How to get a heavy metal test through your doctor

Tell your doctor why you are worried. Name the possible source (renovation of an old house, a job with lead, imported spices or remedies, fish, well water) so the right metal and sample are chosen.
Let the doctor choose the test. For lead, that is usually a venous blood lead test. For arsenic or inorganic mercury, often urine. A panel may be ordered when the source is unclear.
Follow the collection instructions. Labs may ask you to skip seafood for 48 to 72 hours before a urine test and to wait at least 72 hours after a scan with contrast dye (Mayo asks 96 hours for its blood panel).
Go over the results together. Reference ranges differ by lab and sample, and a high result is usually confirmed first.

The CDC says most local health departments can also test children for lead. We do not list prices because they vary by lab, insurer and state.

If lead is found: look for the source

A blood test shows that lead got in, not where it came from. After a high result, the CDC says a doctor may recommend finding and removing lead from the home. Common places to look:

Old paint and dust in homes built before 1978: lead paint testing and dust and soil testing
Drinking water from lead pipes or fixtures: lead water testing
Spices, imported foods and remedies: lead in cinnamon and spices
Dishes and pottery: lead in pottery and dishes
A household member’s work or hobby

A certified risk assessor can check a home for lead hazards; see find a lead professional. For health questions, start with our lead poisoning hub and lead poisoning symptoms.

Frequently asked questions

What does a heavy metal blood test check for?

Usually lead, mercury, arsenic and cadmium, as in Mayo Clinic Laboratories’ blood screen. A doctor can also order one metal alone.

Is a blood or urine test better for heavy metals?

It depends on the metal. Blood is the standard for lead and is used for methylmercury; urine is preferred for arsenic and metallic or inorganic mercury; cadmium can be measured in either.

Can a lead in urine test replace a blood lead test?

No. ARUP Laboratories says venous blood lead is preferred for routine testing; urine lead is for specific situations such as monitoring treatment.

Is a hair test for lead accurate?

No. ATSDR says hair lead is an uncertain estimate of body burden and is not recommended, because hair picks up lead from outside. Ask for a blood test.

My provoked urine test came back high. Do I have heavy metal poisoning?

Not on its own. ACMT says these tests have no valid reference values and that chelators raise urine metals in healthy people too. Ask your doctor about a standard blood or urine test, or a medical toxicologist.

Should I do a heavy metal detox?

No product sold over the counter is approved by the FDA for chelation or detox. Chelation is a prescription treatment that only a doctor decides on.

Lead Screening for Children: When and How Kids Are Tested

Lead screening for children happens at regular checkups: the doctor asks a few questions about lead risks, and many children also get a small blood test at 1 and 2 years old. Children on Medicaid must have that blood test at 12 and 24 months, and a growing number of states now require it for every child.

Parent filling in a clipboard form in a clinic waiting room with a toddler beside them

In short: the American Academy of Pediatrics (AAP) schedule calls for a lead risk assessment at the 6, 9, 12, 18 and 24 month visits and every year from age 3 to 6. Federal Medicaid rules require blood lead tests at 12 and 24 months, plus a test between 24 and 72 months for any child never tested, and a questionnaire alone does not count. States such as Illinois, Michigan, New York and Massachusetts require blood tests for all young children. The test is usually a finger or heel stick. Ask your pediatrician, your local health department or your WIC office which tests your child is due for.

This guide summarizes official guidance and is not medical advice. If you think your child swallowed something with lead in it, call Poison Control at 1-800-222-1222, and call 911 for severe symptoms.

Why children are screened even when they seem healthy

Most children with lead in their blood have no obvious symptoms, and the CDC says all children at risk for lead exposure should be tested. The CDC says children younger than 6 are more likely to be exposed because of their hand-to-mouth behavior. Our lead and children guide explains why young children are most at risk, and lead poisoning symptoms covers the signs that can appear.

“Screening” covers two different things:

Risk assessment: a short set of questions the doctor or nurse asks you about your home, family and habits. No needle involved.
Blood lead test: a small blood sample that measures lead in micrograms per deciliter (µg/dL). This is the only way to know your child’s actual level. See blood lead test for how results are read.

The lead screening schedule at a glance

Federal Medicaid rules, the AAP schedule and CDC guidance; states can add tests.

Age	What’s recommended	Source
6 months	Lead risk assessment (questions) at the well-child visit	AAP Bright Futures
9 months	Risk assessment; in Massachusetts, a blood test once between 9 and 12 months	AAP; Massachusetts DPH
12 months (1 year)	Risk assessment; blood lead test required for children on Medicaid or CHIP-funded Medicaid; blood test for all children in states with universal testing	AAP; CMS (EPSDT); state health departments
18 months	Risk assessment	AAP Bright Futures
24 months (2 years)	Risk assessment; second blood lead test required for Medicaid; blood test in universal-testing states	AAP; CMS (EPSDT); state health departments
2 to 6 years (24 to 72 months)	Risk assessment every year at 3, 4, 5 and 6; blood test for any Medicaid child with no record of a previous test; extra tests in some states (for example ages 3 and 4 in Massachusetts)	AAP; CMS; state health departments
Newly arrived refugee children (up to 16)	Blood test at the domestic medical exam; children 6 and under get a repeat test 3 to 6 months later	CDC refugee health guidance

Medicaid and CHIP: tests at 12 and 24 months

Medicaid’s EPSDT (Early and Periodic Screening, Diagnostic and Treatment) benefit sets the clearest rule. The Centers for Medicare & Medicaid Services (CMS) says all children enrolled in Medicaid, whether coverage is funded through title XIX (Medicaid) or title XXI (CHIP), are required to receive blood lead screening tests at 12 months and 24 months. Any child between 24 and 72 months with no record of a previous blood lead test must also receive one.

Two details from CMS guidance:

Filling out a risk questionnaire does not meet the Medicaid requirement. The blood test itself has to be done.
Medicaid pays for point-of-care blood lead tests done in the doctor’s office, so many families get the result during the same visit.

The AAP Bright Futures schedule for every child

For children not on Medicaid, pediatricians usually follow the AAP’s Bright Futures periodicity schedule. The AAP says it recommends a lead risk assessment at the 6, 9, 12, 18 and 24 month well-child visits and at 3, 4, 5 and 6 years. A blood lead test follows when the risk assessment is positive or when parents are concerned. The AAP also notes that Medicaid programs in many states require a universal blood test at the 12 and 24 month visits.

The CDC names higher-risk groups, including children who live in or spend time in buildings built before 1978, children in low-income households, and immigrant, refugee and recently adopted children. You can always ask for a test.

States that test every child

Many states go further. Examples from state health departments:

Illinois: universal testing took effect July 1, 2026. The Illinois Department of Public Health says all Illinois children are to be tested automatically at 12 and 24 months, and all children 6 and younger are to be assessed for lead exposure with a questionnaire from their health care provider. Before that date, the automatic tests applied only in high-risk ZIP codes.
Michigan: under a 2023 law and rules made final in 2025, physicians are to test, or order a test for, all children at 12 and 24 months, with a test between 24 and 72 months if there is no record of earlier tests. Families may opt out of universal testing.
New York: the state health department says to get children blood lead tested at age 1 and again at age 2, and that providers should assess children from 6 months to 6 years for lead risk at every well-child visit.
Massachusetts: the state requires a blood lead test at least once between 9 and 12 months, again at age 2 and age 3, and at age 4 in communities the state designates as high risk. Children need proof of a lead test to enter child care, preschool or kindergarten.

Rules change, and other states have their own schedules. Your pediatrician or your state or local health department can tell you what applies to your child.

The lead screening questionnaire

The risk assessment is a handful of yes-or-no questions. There is no single national form; states and clinics use their own versions built on CDC guidance. As one example, the South Dakota Department of Health asks:

“Does the child live in or regularly spend time in a home built before 1978?” (It notes this is especially important with chipping or peeling paint or a renovation in the past year.)
“Does the child live with a parent or caregiver who works in an occupation with frequent lead exposure?”
“Does the child have a sibling or playmate with a blood lead level of 3.5 µg/dL or higher?” Or has a parent or caregiver asked for a lead test out of concern?
“Has the child recently arrived in the U.S. as an immigrant, refugee, or foreign adoptee?”

If the answer to any question is “yes” or “I don’t know,” South Dakota advises talking with your child’s health care provider about a blood lead test.

Before the visit, find out when your home and child care setting were built, and think about recent paint work, jobs and hobbies, and imported spices, remedies, dishes, toys or jewelry (see lead in toys and jewelry).

What happens at the test

The CDC describes two ways to take the sample:

Capillary test (finger-prick or heel-prick): usually the first step. A few drops of blood are collected, and results can come quickly, sometimes during the visit. Lead on the skin can get into the sample and make the result read higher than it really is.
Venous test (blood draw from a vein): results take a few days from a lab. It is used to confirm a capillary result at or above the CDC’s blood lead reference value of 3.5 µg/dL.

A high finger-stick number is not a diagnosis on its own. The doctor will usually order a venous test to confirm it, and the timing of that test depends on how high the first result was. What the numbers mean and the CDC’s follow-up steps are explained in blood lead levels and lead poisoning test.

Refugee, immigrant and internationally adopted children

Children from other countries may have been exposed before arriving. For refugees, CDC guidance for the domestic medical exam (done within 90 days of arrival) says:

All refugee infants and children up to 16 years old should get a blood lead test.
Children 6 and younger should get a repeat test whatever the first result was; if it was below 3.5 µg/dL, within 3 to 6 months after the first screening.
Older children with an elevated first result, or with risk factors such as a sibling with an elevated level, may need follow-up testing too.
Newly arrived pregnant or breastfeeding women and girls should also be screened.

Where to get your child tested, and what it costs

Your child’s doctor or clinic. The usual place, often at the 1 and 2 year checkups.
Your local health department. The CDC says health care providers and most local health departments can test for lead in blood.
WIC. If your family uses WIC, ask your WIC office whether it offers lead testing or can refer you to a place that does.

Cost: the CDC says Medicaid covers testing for enrolled children and many private insurance plans cover it. Without coverage, prices are not standardized, so we don’t list them; ask your local health department about options.

What you can do while you wait

You can start looking for lead around your child now. These steps from the CDC and EPA don’t replace testing:

If your home was built before 1978, look for peeling or chipping paint, especially on windows, doors and porches, and keep children away from it. Our lead paint testing guide explains your options.
Wet-mop floors and wipe windowsills, wash hands and toys often, and take shoes off at the door.
Use cold tap water for drinking, cooking and baby formula.
Check toys, jewelry, spices and dishes against FDA and CPSC recalls.

Frequently asked questions

At what age should my child have a lead test?

Blood tests are due at 12 and 24 months for children on Medicaid and in universal-testing states, with a catch-up test by age 6 if missed. The AAP adds risk questions at every well-child visit from 6 months to 6 years.

Does my 1 year old need a lead test?

On Medicaid or in a universal-testing state, yes: the first blood test is due at 12 months. Otherwise the doctor asks risk questions and recommends a test if there is risk or if you ask.

My child was tested at 1. Do they need another test at 2?

Under Medicaid rules and in states such as Illinois, Michigan and New York, yes. A result below the reference value at 12 months does not rule out exposure later.

Is the lead screening questionnaire enough?

Not for children on Medicaid: CMS says a risk questionnaire does not meet the requirement, and the blood test must be done. For other children, the questionnaire helps the doctor decide whether a blood test is needed. Only a blood test shows your child’s actual level.

Can I test my child for lead at home?

No. Only a blood test through a doctor, health department or lab measures lead in a child. Home kits test surfaces or water, which can help find a source.

Blood Lead Levels: What Your Lead Test Results Mean

There is no “normal” lead level in blood that is known to be safe: the CDC says no safe blood lead level in children has been identified. What a result can tell you is how your number compares with official benchmarks, such as the CDC’s blood lead reference value of 3.5 µg/dL, and what health agencies say should happen next.

Doctor explaining results to an adult patient in an exam room

In short: blood lead results in the US are given in micrograms per deciliter (µg/dL). For children, the CDC’s reference value is 3.5 µg/dL: a level at or above it is higher than in 97.5% of US children aged 1 to 5, and it starts follow-up. In pregnancy, CDC guidance starts follow-up at 5 µg/dL. OSHA requires removal from lead work at 50 to 60 µg/dL, a legal limit, not a safe level. A high finger-stick result needs a venous test to confirm it. Your doctor or health department decides what your number means for you.

Children's blood lead levels and CDC follow-up

No safe blood lead level has been identified. A capillary result above 3.5 is confirmed with a venous test. Source: CDC

This guide explains what official sources say about the numbers. It is not medical advice. For questions about a possible poisoning, call Poison Control at 1-800-222-1222; for severe symptoms, call 911. How the test itself is done, and who should be tested, is covered in our blood lead test guide.

How to read the number on your lead test results

US labs report a blood lead level (BLL) in µg/dL, micrograms of lead per deciliter of blood. The OSHA general industry standard writes it as µg/100 g of whole blood.

Labs outside the US often use micromoles per liter (µmol/L). The CDC’s guidelines for pregnant and lactating women give the conversion as 1 µg/dL = 0.0484 µmol/L. So 5 µg/dL is about 0.24 µmol/L, 10 µg/dL about 0.48 µmol/L, and the 3.5 µg/dL reference value about 0.17 µmol/L. If your report is in µmol/L, multiply by about 20.7 to get µg/dL, or ask the lab to state it in µg/dL.

On your report, also look for three details:

Sample type: capillary (finger-stick or heel-stick) or venous (from a vein). The CDC says a capillary result at or above the reference value should be confirmed with a venous sample, because lead on the skin can make a finger-stick read high.
“Less than” results: a value reported as below a limit (for example “<1”) means the lab cannot measure lower than that, not that there is zero lead.
The date: a blood test mostly reflects recent and ongoing exposure. Comparing results over time is how doctors see whether a level is going up or down.

Is there a normal lead level in blood?

Not in the sense of a safe range. The CDC’s 2021 report on the reference value states that no safe blood lead level in children exists, and the CDC says any detectable lead means a child has been exposed. The CDC’s 2010 guidelines on pregnancy say the same about pregnancy: no level has been found below which harmful effects do not occur.

What people often mean by “normal” is “typical.” CDC guidance notes the average US blood lead level fell from about 13 µg/dL in the 1970s to under 2 µg/dL by the mid-2000s, so most people today have a low number. Typical is not the same as harmless.

The CDC blood lead reference value (3.5 µg/dL) explained

The blood lead reference value is a statistical marker, not a health limit. The CDC sets it at the 97.5th percentile of blood lead levels in US children aged 1 to 5, measured by the National Health and Nutrition Examination Survey (NHANES). A child at or above it has more lead in their blood than 97.5% of children that age.

2012: the CDC introduced the reference value at 5 µg/dL, replacing the older “level of concern” of 10 µg/dL.
October 2021: the CDC lowered it to 3.5 µg/dL, using NHANES data from 2015 to 2018.
Going forward: the CDC says it reviews the two latest NHANES cycles every four years, so the number can change again.

It is a way to find the children with the most exposure and act there first, not a line between safe and unsafe. More on children is on our lead and children page.

What is an elevated blood lead level?

“Elevated” depends on who is using the word and for what purpose. These are the benchmarks official sources use today:

Number	What it is	Who uses it
3.5 µg/dL	Blood lead reference value for children aged 1 to 5 (97.5th percentile)	CDC, since October 2021
3.5 µg/dL	Reference value in the national “lead in blood” case definition, for children and adults (confirmed by a venous test, or two capillary tests in a child under 16)	CSTE (Position Statement 22-EH-01) and CDC national surveillance, 2023 definition
5 µg/dL	Level used to flag an elevated adult result for surveillance	NIOSH Adult Blood Lead Epidemiology and Surveillance (ABLES) program, per its guidance page (April 2024)
5 µg/dL	Level in pregnancy that should trigger follow-up testing, education and a search for the source; NIOSH says a pregnant person should not exceed it	CDC 2010 pregnancy and lactation guidelines; NIOSH
10 µg/dL	Pregnant women at or above it should be removed from work exposure to lead	CDC 2010 pregnancy and lactation guidelines
40 µg/dL	Mothers at or above it (confirmed) are advised to pump and discard breast milk until the level drops below 40	CDC 2010 pregnancy and lactation guidelines
50 / 60 µg/dL	Medical removal from lead work	OSHA lead standards (see the workers section below)

Note the gap between the public health numbers (3.5 to 10 µg/dL) and the OSHA workplace numbers (40 to 60 µg/dL). The OSHA standards date from 1978 and 1993.

Blood lead level chart for children: what the CDC says happens next

The CDC publishes recommended actions for health care providers by a child’s blood lead level. This is a summary to help you follow the conversation with your child’s doctor. The doctor and your local health department decide the actual plan.

Child’s blood lead level	Confirm a capillary result with a venous test within	What the CDC lists for providers
Below 3.5 µg/dL	No confirmation needed	Education about lead sources, developmental checks, diet review (iron and calcium), retesting by age and risk
3.5 to 9 µg/dL	3 months	All of the above, plus: report to the state or local health department, exposure history, environmental investigation as required, check for iron deficiency, follow-up testing
10 to 19 µg/dL	1 month	Same as 3.5 to 9, with follow-up testing sooner
20 to 44 µg/dL	2 weeks	All of the above, plus: full history and physical exam, environmental investigation and lead hazard reduction, other medical checks; the doctor may consult a Pediatric Environmental Health Specialty Unit or Poison Control
45 µg/dL or higher	48 hours	Urgent medical evaluation, including a detailed neurological exam; hospital admission if there are symptoms or the home is not lead-safe; the doctor consults a medical toxicologist about treatment

The retesting schedule for each band is in our blood lead test guide. Treatment decisions belong to the child’s doctor; our lead poisoning treatment page explains what official guidance describes. Do not use home remedies or supplements sold to “detox” lead.

Blood lead levels in pregnancy and breastfeeding

Lead can pass from mother to baby. The CDC’s Guidelines for the Identification and Management of Lead Exposure in Pregnant and Lactating Women (2010) do not recommend testing every pregnant woman; they recommend testing based on risk factors. They call for follow-up testing, education and environmental, nutritional and behavioral steps for every pregnant woman at 5 µg/dL or higher, and they recommend a venous sample for testing in pregnancy. The follow-up schedule:

Venous blood lead level in pregnancy	Follow-up testing (CDC 2010, Table 5-3)
Below 5 µg/dL	No follow-up testing indicated
5 to 14 µg/dL	Within 1 month; a maternal or cord blood lead level at delivery
15 to 24 µg/dL	Within 1 month, then every 2 to 3 months; a level at delivery
25 to 44 µg/dL	Within 1 to 4 weeks, then every month; a level at delivery
45 µg/dL or higher	Within 24 hours, then at frequent intervals; consultation with a clinician experienced in lead exposure in pregnancy is strongly advised

The same guidelines say pregnant women at 10 µg/dL or higher should be removed from occupational lead exposure. For breastfeeding, mothers below 40 µg/dL are encouraged to breastfeed; mothers with a confirmed level of 40 µg/dL or higher are advised to pump and discard their milk until their level drops below 40 µg/dL. If you are pregnant or nursing, your obstetric provider and your baby’s pediatrician decide what applies to you.

Blood lead levels for adults and workers

Most adults with a raised level were exposed at work (construction, battery recycling, firing ranges, smelting and similar jobs), through a hobby, a home renovation or a contaminated product. The national surveillance definition counts an adult venous result at or above 3.5 µg/dL as a case of “lead in blood,” and the NIOSH ABLES program uses 5 µg/dL to flag an elevated adult level. See lead testing for adults for when adults get tested.

For workers covered by OSHA’s lead standards, the law sets these blood lead triggers:

Rule	General industry (29 CFR 1910.1025)	Construction (29 CFR 1926.62)
Routine blood testing	At least every 6 months for covered workers	At least every 2 months for the first 6 months, then every 6 months
Test more often	At least every 2 months once a result is 40 µg/dL or higher, until two in a row are below 40	Same: every 2 months at 40 µg/dL or higher, until two in a row are below 40
Medical removal from lead work	A test and follow-up test at or above 60 µg/dL, or an average of the last three tests, or of all tests over the past 6 months (whichever covers the longer period), at or above 50 µg/dL, unless the last test was below 40	A test and follow-up test at or above 50 µg/dL
Return to the job	Two tests in a row below 40 µg/dL	Two tests in a row below 40 µg/dL

These are minimum legal requirements, not health targets. NIOSH’s guidance page notes that medical groups recommend acting much earlier: for example, California’s health department recommends retesting adults every 3 months at 3.5 to 9 µg/dL, and AOEC, ACOEM and California recommend medical removal after one result above 30 µg/dL. If you work with lead, tell your doctor.

Why a finger-stick result needs a second test

Lead dust on the skin can get into a finger-stick sample and make it read high, so the CDC recommends confirming a capillary result at or above 3.5 µg/dL with a venous draw. The national case definition works the same way: a single capillary result in a child counts as “suspect,” while a venous result, or two capillary results within 12 weeks, counts as “confirmed.”

Questions to ask your doctor about a lead result

Was this a capillary or a venous sample? Does it need a venous test to confirm it, and by when?
What is the exact number and unit, and how does it compare with my (or my child’s) earlier results?
When should the next test be?
Has the result been reported to the health department, and will they offer a home visit or environmental investigation?
Which sources should we look for first: old paint and dust, water, soil, a job or hobby, spices, cosmetics, remedies or dishes?
Should other family members, or a pregnant household member, be tested too?

Finding the source matters as much as the number. Our lead poisoning causes and prevention guide walks through the common ones, and lead poisoning symptoms explains why many people with lead in their blood have no symptoms at all. For the bigger picture, see the lead poisoning hub.

Frequently asked questions

What is a normal lead level in blood?

There is no known safe level. Most people in the US have low levels today, and the CDC uses 3.5 µg/dL as a reference value: a child at or above it has more lead than 97.5% of US children aged 1 to 5. A result below that is common, but it is not a guarantee of no harm.

What blood lead level is considered elevated?

For children, a level at or above the CDC reference value of 3.5 µg/dL. The national case definition uses 3.5 µg/dL for adults too, while the NIOSH ABLES program flags adults at 5 µg/dL. In pregnancy, CDC guidance starts follow-up at 5 µg/dL.

Is 2 µg/dL of lead in blood bad?

It is below the CDC reference value, so it does not trigger the follow-up for elevated levels. The CDC still says any detectable lead means exposure, so ask your doctor about likely sources.

Can I lower my blood lead level at home?

The main step official sources describe is stopping the exposure, which usually means finding the source with help from your health department or a lead poisoning test and home investigation. Any medical treatment is your doctor’s decision. Do not take supplements or products sold to remove lead without your doctor’s advice.
