New requirements for blood lead testing of young children: By law, Michigan now requires blood lead testing for all children at 12 months and 24 months of age and at other intervals based on exposure risk. This approach is commonly called “universal blood lead testing”. It is the physician’s responsibility to test or order the test.
The law updates the Public Health Code, adding MCL 333.5474d and amending MCL 333 9206(1). Administrative rules (R 330.301-304) for implementation of the law were made official on April 30, 2025.

Every Michigander deserves safe, clean drinking water. To protect its residents, Michigan has adopted the strictest Lead and Copper Rule in the nation. This rule strengthens our ability to detect lead in drinking water and will help protect your family's health.
Michigan is committed to protecting the public from lead exposure by working together with families and local communities to reduce or eliminate all sources of lead in the home. When lead is swallowed, it can cause health problems, especially in children. By creating the strongest drinking water lead testing and service line removal rules in the country, Michigan is on track to reduce and get rid of lead drinking water pipes.
While lead in drinking water is concerning, lead can also come from other sources. Exposure to lead-based paint chips and dust, as well as soil with higher levels of lead, are most often to blame when it comes to having elevated levels of lead in the body. In addition to community testing results, this website will help you identify other possible sources of lead in your home and ways to remove it.
