A member asked:

How could chorionic villi sampling determine whether a fetus has genetic abnormalities?

A doctor has provided 1 answer

CVS: Chorionic villus sampling is a procedure to obtain a small amount of tissue from the placenta. The placenta has the same genetic endowment as the fetus. So chromosomal or genetic testing of the chorionic villus will tell about the fetus.
