MI HB4678

Requires physicians treating minors to screen for lead poisoning at intervals and using methods specified by the Michigan Department of Health and Human Services, effective January 1, 2022.

Mandates documentation of lead poisoning screening on each minor's certificate of immunization.

Establishes minimum screening requirements: once between ages 9-12 months, again at ages 2 and 3 years, and at age 4 if the minor resides in a high-risk geographic area identified by the department.

Requires additional screening for minors identified as high-risk based on factors including living with another minor diagnosed with lead poisoning or residing in a pre-1978 home without visual lead risk inspection.

Exempts minors whose parent, guardian, or person in loco parentis objects on religious grounds; bill takes effect only if HB 4679 or a corresponding Senate bill is enacted.
