How are amniocentesis and chorionic villi sampling are used in genetic screening?

Amniocentesis involves taking a sample of the amniotic fluid and checking the fluid for fetal tissue, metabolites, and other markers that would indicate that there is a problem with fetal development. Fetal genetic testing can be performed on the fetal cells in the amniotic fluid. Chorionic villi sampling essentially involves collecting a specific part of the placenta for genetic analysis. Since the placenta is the same genotype as the fetus it is possible to make a genetic diagnosis of the fetus based on analyzing the placenta. Chorionic villi sampling is less invasive and therefore less likely to cause fetal distress.
