Childhood Blood Lead Levels in North Carolina

Why blood lead testing matters

Blood lead levels are the only way to know if a child has been exposed to lead. Even small amounts can affect brain development, behavior, and school performance. North Carolina tracks these levels through its pediatric screening program to identify children who need care and communities where exposure is happening.

North Carolina's screening program

North Carolina requires blood lead testing for children ages 1–5 through Medicaid and the Childhood Lead Poisoning Prevention Program (CLPPP). The state health department's Division of Environmental Health and Safety oversees lead surveillance and prevention efforts.

All children on Medicaid must be tested at least once. For uninsured and underinsured children, the CLPPP provides free screening through participating clinics and health departments in all 100 counties. Testing is done with a simple finger prick or blood draw—results typically come back within days.

What the data shows

The CDC tracks the percentage of children in each North Carolina county with confirmed elevated blood lead levels (≥3.5 µg/dL). These county-level percentages vary widely and help identify where exposure risks are highest. Lead in drinking water, painted surfaces in older homes, soil, and occupational exposure are all sources.

If your child has an elevated result, your healthcare provider will talk with you about next steps—including home inspection, water testing, and follow-up testing to monitor trends.

How to access data

To request your county's current blood lead surveillance data or to find a screening location near you:

  • Contact the NC Division of Environmental Health and Safety, Lead Poisoning Prevention Program
  • Call your local health department (county-level offices can connect you to screening services)
  • Visit the NC Division of Public Health website for county contacts and resources

Water from your tap is just one source of lead exposure. A full picture includes your home's age, condition, and any renovation history.

Next steps for residents

  • Ask your child's pediatrician about blood lead screening—it's free for Medicaid-enrolled children and available low-cost through county health departments
  • If your home was built before 1978, assume painted surfaces may contain lead; get a professional assessment before any renovation
  • Contact your water utility about their lead service line inventory and any available testing programs

Common questions

What is a normal blood lead level for children?

The CDC considers ≥3.5 µg/dL elevated and recommends follow-up. Lower is always safer; there's no safe threshold. Your pediatrician will interpret your child's specific result and recommend next steps.

Is my child's water the only way they get lead exposure?

No. Lead paint in homes built before 1978, contaminated soil, and dust are often bigger sources than drinking water. A combination of sources determines a child's total exposure.

How do I find blood lead testing in North Carolina?

Contact your pediatrician or local health department. All children on Medicaid are eligible for free screening; low-income uninsured children can access testing through the Childhood Lead Poisoning Prevention Program in every county.

Can high blood lead levels in children be reversed?

Removing or controlling the source stops further exposure, which prevents ongoing harm. Talk to your pediatrician or pediatric lead specialist about managing existing levels and protecting your child going forward.
