How is done?
During , a sample of chorionic villus cells is taken and checked for problems. Chorionic villi are tiny fingerlike growths in the placenta. The genetic material in these cells is the same as that in the fetus's cells.

CVS is usually performed between the 10th and 12th weeks of pregnancy. Unlike amniocentesis (another type of prenatal test), CVS does not provide information on neural tube defects, such as spina bifida.
