Protecting Children’s Health with Early Lead Detection
Lead exposure can happen quietly — without obvious symptoms — but it can have lasting effects on a child’s growth, learning, and development. That’s why routine lead screening is an important part of preventive care.
At the Macoupin County Public Health Department, we provide lead screening to help identify exposure early and connect families with the guidance and support they need to stay healthy and safe.
Why Lead Screening Matters
Lead is a toxic metal that can be found in older homes, paint, soil, plumbing, and some consumer products. When lead enters the body — even in small amounts — it can interfere with brain development and other vital functions.
Because children’s bodies and brains are still developing, they are especially vulnerable to lead exposure.
Early screening helps:
- Detect lead exposure before symptoms appear
- Protect brain development and learning ability
- Prevent long-term health and behavioral problems
- Identify environmental risks in the home or community
- Connect families to treatment and prevention resources
The good news: lead exposure is preventable — and early detection makes a big difference.

Frequently Asked Questions
Is lead screening required?
Lead screening is recommended for some children who may be at a higher risk of lead poisoning. Your provider can help determine if lead screening is recommended for your child. If your child is enrolled in an Illinois public school, lead screening is required for entrance into pre-kindergarten and/or kindergarten.
How often should my child be tested?
Most children are screened at ages 1 and 2. Additional testing may be recommended based on risk factors.
What happens if my child has high lead levels?
We will explain the results, recommend next steps, and help coordinate follow-up care or environmental support if needed.
Is the test safe?
Yes. Lead screening uses a small blood sample and is safe for children of all ages.
Does insurance cover lead screening?
Lead screening is often covered by insurance, especially for young children. If your child does not have insurance or their insurance will not cover lead screening, this test can be completed through the Illinois Department of Public Health lab at no cost.
