About the newborn screening program

Newborn Screening is a public health program that screens all babies for many serious but treatable genetic disorders. All babies born in California are required to get screened soon after birth.

Newborn screening began in California in 1966 with screening for one disorder, phenylketonuria (PKU). The Program has expanded and now includes 80 different genetic and congenital disorders. The goal of the program is to identify babies with these disorders early, so that treatment can be started right away.
