Welcome to the Michigan BioTrust for Health (BioTrust) website! The BioTrust is a program to oversee our state's stored blood spots and their use in health research. Five to six blood spots are collected from almost every newborn shortly after birth for newborn screening. After newborn screening is performed at the state laboratory, any unused blood spots (including parts of blood spots) are stored indefinitely (forever) unless a parent or grown child (18 years or older) opts-out. De-identified stored blood spots can be used for research. The choice to allow research use is yours to make. Please explore this website to learn more!
