Who Should Consider Prenatal Diagnostic Testing?

The American College of Obstetricians and Gynecologists (ACOG) recommends offering the option of chorionic villus sampling (CVS) or amniocentesis to all pregnant women for the prenatal diagnosis of chromosome abnormalities.

Testing should specifically be considered for women who:

  • Will be over the age of 35 at delivery
  • Have an abnormal screening test, such as a first trimester screen, quad screen, sequential screen, or non-invasive prenatal screening (NIPS)
  • Have certain abnormalities seen on ultrasound
  • Have had a previous pregnancy with a chromosome abnormality
  • Have an inherited predisposition to chromosome abnormalities
  • Are at risk for a prenatally diagnosable inherited genetic disorder
