It describes the Newborn Screening Quality Assurance Program (NSQAP) at the CDC in Atlanta, Georgia, which provides services for laboratories that use specimens of dried-blood spots (DBSs) to perform newborn screening tests. The mission of this program is to improve interlaboratory comparability and to work toward interlaboratory standardization.
