Lead Blood Test: What to Expect

A lead blood test measures the amount of lead in a person's blood. Lead is a heavy metal that can be harmful to health, especially for children. Young children are more susceptible to lead poisoning because their bodies are still developing and they absorb lead more easily than adults.

Lead can cause a variety of health problems, including:

- Brain damage

- Learning disabilities

- Behavior problems

- Growth problems

- Hearing loss

- Kidney damage

A lead blood test is typically recommended if a person has been exposed to lead or if they are at risk for lead poisoning. Risk factors for lead poisoning include:

- Living in a house built before 1978, as those buildings are more likely to have lead-based paint

- Having a job that involves working with lead, such as construction, manufacturing, or mining

- Using lead-glazed pottery or drinking water from lead-contaminated sources

A lead blood test can be done at a doctor's office or a laboratory. The test involves taking a small sample of blood from a vein in the arm. The blood is then sent to a laboratory for analysis.

The results of a lead blood test are reported in micrograms per deciliter (µg/dL). The Centers for Disease Control and Prevention (CDC) has set a reference level of 5 µg/dL for adults and children. This means that a blood lead level of 5 µg/dL or higher is considered elevated and may be associated with health problems.

If a person has an elevated blood lead level, they will need to see a doctor to discuss treatment options. Treatment for lead poisoning typically involves taking a medication called chelation therapy, which helps to remove lead from the body.

If you think you or your child may have been exposed to lead, talk to your doctor about getting a blood test. Early detection and treatment of lead poisoning can help to prevent serious health problems.
