The California Prenatal Screening (PNS) Program focuses on detecting birth defects during pregnancy.

The PNS program works to ensure that prenatal screening services and follow-up diagnostic services, where indicated, are available to all pregnant women in California. Prenatal screening identifies individuals at increased risk for carrying a fetus with a specific birth defect. The PNS Program provides pregnant women with a risk assessment for open neural tube defects (NTD), Down syndrome (trisomy 21), trisomy 18 and SLOS (Smith-Lemli-Opitz Syndrome) through one or two blood tests. 

The program currently offers three types of prenatal screening tests (see below) to pregnant women in order to identify individuals who are at increased risk for carrying a fetus with a specific birth defect. The fee for the Prenatal Screening Program is $221.60, whether a woman has one or two blood tests.

The screening test indicates risk, but does not diagnose fetal birth defects.  For women with screening results indicating a high risk for a birth defect, the Program provides free follow-up diagnostic services at State-approved Prenatal Diagnostic Centers. Services offered at these Centers include genetic counseling, ultrasound, and amniocentesis. Participation in the screening tests and follow-up services is voluntary.
