Chorionic villus sampling (CVS) refers to the withdrawal and analysis of cells from the membranes that surround the fetus, either with a syringe or with a catheter. Both amniocentesis and CVS involve the collection of cells for karyotyping, but because more cells are collected in this procedure than in amniocentesis, the test can be completed more quickly.
