Michigan Department of Health and Human Services allegedly collects blood samples from newborns without parents’ consent, tests them, then transfers them to a nonprofit corporation, “where they are stored for future use by the state.” Parents sue on behalf of themselves and their children. Sixth Circuit: Most of the claims are nonstarters, but Michigan’s ongoing storage of the blood samples may violate the kids’ Fourth Amendment rights and the parents’ Fourteenth Amendment right to direct their offspring’s medical care.
