California Newborn Screen

All newborns born in the state of California are screened for a variety of hematologic, metabolic, and endocrine disorders. Testing is usually done in the hospital with the first 2 days.  For infants born at home or in an alternative birthing center, testing may be done in a clinic or other laboratory, but must be drawn between 12 hours and 6 days of age.  Because early testing may result in false negatives for PKU in particular, any newborn tested before 12 hours of life requires a repeat newborn screen.
