This study will assess whether the Michigan Department of Community Health’s policy requiring parental consent for research use of residual newborn screening dried blood samples leads to the maintenance of a robust sample collection that supports population health-based research.

This study will determine whether Michigan's consent model for the use of these samples ensures: (1) the integrity of the state newborn screening program, (2) the maintenance of a robust sample collection that supports population-based research, and (3) informed decision-making by parents. The potential impact is far-reaching. These results will help inform the development of other state policies regarding this contentious issue.
