The law requires doctors to test one- and two-year-olds for lead... and for records to be reported to health departments.
Ellen Vial is a member of the Michigan Alliance for Lead Safe Homes. She says universal testing can help identify - and phase out - sources of lead - either from water lines, paint in historic houses, or antique objects.
"People think about something when there's an emergency or crisis, but they don't think about how it could impact their families or their communities on a day-to-day basis."
Childhood exposure to lead can result in behavioral disorders, intellectual disabilities, anemia, low bone and muscle density, and kidney damage.
