PLDadmin Starting April 2025, Michigan took a huge step forward in protecting children’s health by adopting universal blood lead testing. This change means every child in the state will have important screenings at key ages, helping to catch and address lead exposure early—before it can cause lasting harm.
If you’re a parent, caregiver, healthcare provider, teacher, or work in any career that supports children, this guide will help you understand what the law says, why it matters, and how to take action.
Why This Law Is So Important
Lead is a toxic metal that can harm a child’s brain, behavior, and growth—even at very low levels. According to the Centers for Disease Control and Prevention, there is no safe level of lead in the blood.
In Michigan, risks often come from:
Older homes built before 1978 with lead-based paint
Dust and soil contamination
Drinking water from lead service lines or old plumbing
Certain imported toys, cookware, or products
Jobs or hobbies that involve lead
The new law ensures every child is tested, not just those already considered “at risk,” which means fewer cases go undetected and more children get the help they need sooner.
Who Gets Tested and When
Under the new rules (R 330.301–R 330.304), physicians must test or order a blood lead test for children:
At 12 months old
At 24 months old
Catch-up testing any time between ages 2–6 if the child has never been tested
Extra testing for children who:
Live in one of over 80 high-risk cities or townships between ages 4–5
Live in a home built before 1978
Live with another child diagnosed with lead poisoning
Have other risk factors identified by their doctor
How the Test Works
Two main types of tests are used:
Capillary test (finger or heel stick) – a quick screening
Venous test (from a vein) – more accurate, and required if the capillary test shows 3.5 µg/dL or higher

Keeping Track of Results
All test results must be added to the Michigan Care Improvement Registry (MCIR) and included on the child’s official certificate of immunization. This helps doctors, parents, and public health teams keep a complete record of a child’s health screenings.
Your Right to Choose
While the law strongly encourages testing, parents and guardians may opt out. If you choose this, your decision will be documented in your child’s medical record.
What This Means for People Who Work with Kids
If you’re a childcare provider, teacher, social worker, nurse, or pediatric care provider:
Know the rules so you can answer questions confidently
Encourage testing when you see possible environmental risks
Share resources for free or low-cost testing
Be proactive in spotting signs of possible lead exposure
Cost and Coverage
The good news—blood lead testing is considered a preventive service under the Affordable Care Act. That means most insurance plans must cover it with no extra cost to families. Local health departments also offer free or low-cost testing.
Preventing Lead Exposure at Home
Testing is just one part of the solution. Prevention keeps children safe. You can:
Use a certified lead-reducing water filter if your home may have lead pipes (EPA guide)
Keep floors, window sills, and play areas clean
Wash children’s hands and toys often
Hire only EPA-certified contractors for renovations (find one here)
Questions & Answers
1. What does the test measure?
It measures the amount of lead in your child’s blood.
2. Why test at 12 and 24 months?
That’s when children are most likely to come into contact with lead as they explore their environment.
3. What if my child has never been tested?
They can still be tested anytime up to age 6.
4. Do I have to live in a high-risk area?
No—testing is for all children in Michigan at the required ages.
5. Will insurance cover it?
Yes, in most cases it’s fully covered.
6. Can I refuse the test?
Yes, parents may object and have it recorded in the child’s file.
7. What if the test shows high lead levels?
Your doctor will order a confirmatory test and connect you with resources to find and fix the lead hazard.
The Bottom Line
This law is about giving every Michigan child the best chance at a healthy future. By testing early and often, we can protect kids from the harmful effects of lead before it’s too late.
