Prenatal Genetic Screening

Many genetic abnormalities can be diagnosed before birth. Your doctor may recommend genetic testing during the pregnancy if you or your partner have a family history of genetic disorders and/or you have had a fetus or baby with a genetic abnormality. Genetic testing is not required.

Examples of genetic disorders that can be diagnosed before birth include the following:

  • Cystic fibrosis
  • Duchenne muscular dystrophy
  • Hemophilia A
  • Thalassemia
  • Sickle cell anemia
  • Polycystic kidney disease
  • Tay-Sachs disease

Genetic screening methods may include the following:

  • Ultrasound scan
  • Alpha-fetoprotein test (AFP) or multiple marker test
  • Chorionic villus sampling (CVS)
  • Amniocentesis
  • Percutaneous umbilical blood sampling (withdrawing a small sample of the fetal blood from the umbilical cord)
