Testing for Lead Exposure

There are two testing methods determining whether a child has been exposed to lead. One involves taking blood from a finger (capillary) and the other from a vein (venous).

• All children should be tested at both 12 and 24 months of age.
• Children 2 - 6 years that have never been tested.
• Children 6-17 years that have a known or suspected source of lead.

• Your child’s health care provider may offer blood lead testing in the office or provide a prescription to take your child to a laboratory.
• Federally Qualified Health Centers (FQHC) can provide or arrange testing.

• If you are unsure if your insurance policy covers the cost of lead testing, it is best to reach out to your Insurance company using the number provided on your insurance card.

Your child’s health care provider will explain the test results, tell you when retesting is needed, and provide prevention information.

You may be asked the following questions to determine if your child needs testing more frequently than New Jersey’s testing law. 

• Does your child live in or regularly visit a house with peeling or chipping paint built before 1978?
• Does your child live in or regularly visit a house built before 1978 with recent, ongoing or planned renovations?
• Does your child live with an adult whose job or hobby involves exposure to lead?
• Did your child have an elevated blood lead level the last time he or she was screened?

Your child's health care provider will:

• Tell you when your child needs to be retested.
• Provide prevention information to reduce or eliminate your child’s further exposure.
• Work with your local health department.

Your local health department will:

• Arrange a home visit by a nurse case manager. Depending on the blood lead level, a Lead Inspector Risk Assessor will be added to the case and will accompany the visiting nurse.
• Educate you about the effects and prevention of elevated blood lead levels.
• Assist in testing of siblings, other children and pregnant women living in the same household.
• Educate about nutrition, handwashing, housekeeping, and other ways to reduce your exposures.
• Assess your family’s needs for community resources.
• Collect information about your home.
• Test painted surfaces only if a Lead Inspector Risk Assessor has been assigned to the case based on the blood lead level.
• Determine sources of lead exposure in your neighborhood.
• Test other possible sources of lead such as: consumer products, toys, spices, dinnerware/dishes, jewelry, cosmetics.
