Welcome to the State of California 

California Newborn Screening Program

Limitations of Screening

Screening is the testing of a group of people to identify those who are at risk for having a specific disease even though they may seem healthy. Newborn screening identifies most, but not all, of the babies who have one or more of the many diseases screened for by the California Program.

While a positive screening result identifies newborns at an increased risk to justify a diagnostic work-up, a negative screening result does not rule out the possibility of a disorder. Parents should remain watchful for any sign or symptoms of these disorders in their child and consult a physician.
