Information for Individuals and Families

Pregnancy can cause feelings of joy, as well as fear, stress, and uncertainty about the future. Some expecting parents want to know as much as they can about their fetus (developing baby) during pregnancy.

Positive pregnancy test 

Prenatal screening offered through the California Prenatal Screening Program is a way to check on your fetus during pregnancy for genetic conditions and birth defects. You decide if you want prenatal screening. Your prenatal care provider should discuss this information and your choice with you early in your pregnancy.
