Is there testing to find out the risk of having a baby with a birth defect?

Yes. Prenatal screening tests assess the risk that a baby will be born with a specific birth defect or genetic disorder. Prenatal diagnostic tests can detect if a fetus has a specific birth defect or genetic disorder. Every woman should review the available testing options with her obstetrician–gynecologist (ob-gyn) or other health care professional so that she can make an informed choice.
