Lead Blood Test

What Is a Lead Test and Why Is It Done?

A lead blood test (or lead testing) measures the amount of lead in the body. Lead is a metal that’s found in the environment and in many consumer products.

Even low levels of lead in the blood can be harmful, so doctors ask questions to see if a child is at risk for lead exposure and should have a lead test.

Top Things to Know

• A lead blood test checks for lead, a metal that can harm kids’ health.
• Lead can be found in many products and the environment.
• Doctors screen for lead exposure by asking questions to see if a test is needed.
• Your doctor can explain what the results of the lead test mean.

What Is Lead Poisoning?

Too much lead in the body is called lead poisoning. It can lead to problems in kids, like learning disabilities, behavior problems, and anemia (when the number of red blood cells in the body gets too low). Very high levels of lead can cause serious problems, like seizures or a coma.

Lead poisoning can happen when kids breathe in lead dust or eat or drink something contaminated by lead. The metal can be in things like old paint, water from lead pipes, soil near old buildings or highways, and some toys, dishes, or traditional medicines. Children can also be exposed if someone in the home brings in lead dust from work or hobbies.

When Is a Lead Test Given?

Lead tests are given during regular checkups if a doctor thinks there’s a high chance that a child has been exposed to lead. Some states and programs ask for every child to be tested at 12-month and 24-month checkups.

How Can I Help My Child Prepare for a Blood Test?

To help kids get ready for a blood test, find out if they need to fast (not eat or drink) or should stop taking medicines before the test. Explain what to expect during the test. If your child is nervous about it, work together on ways to stay calm. Deep breathing or even imagining being in a place that makes your child feel safe and relaxed can help.

What Do Lead Test Results Mean?

Your doctor will explain what the lead test results mean. While there’s no safe or “normal” lead level, doctors use the amount found to decide what steps to take. If the results show lead, the first step is to stop more lead exposure. Your home will be checked for lead and siblings will be tested too. 

Kids with higher lead levels may need medicine in the hospital to help remove the metal from the body as part of their lead poisoning treatment.

What Else Should I Know?

Lead can pass to a baby during pregnancy. If you’re pregnant and think you’ve been exposed to lead or were exposed in the past, talk with your doctor about getting a blood test to check lead levels.

If you have questions about the lead test or what the results mean, ask your doctor.
