Tests and Procedures

Genetic testing can evaluate the health of both mother and baby even during the first trimester. Genetic tests or procedures may include:

  • Ultrasound – A non-invasive screening that produces an image of the fetus using sound waves
  • Amniocentesis – A diagnostic procedure that involves the insertion of a thin needle through the abdomen in order to obtain a sample of the amniotic fluid that surrounds the fetus. Cells in the fluid can be analyzed for chromosome abnormalities and other genetic disorders.
  • Chorionic villus sampling (CVS) – A diagnostic procedure to extract cells from the placenta between 10 and 13 weeks of pregnancy. The procedure extracts cells from the placenta in order to detect chromosome abnormalities and certain other genetic disorders.
