Chorionic villus sampling (CVS) is a prenatal test that is used to detect birth defects, genetic diseases, and other problems during pregnancy. During the test, a small sample of cells (called chorionic villi) is taken from the placenta where it attaches to the wall of the uterus. The transabdominal procedure is performed by inserting a needle through the abdomen and uterus and into the placenta. Ultrasound is used to help guide the needle, and a small amount of tissue is drawn into the syringe. The sample is placed in a dish and evaluated in a lab. Chorionic villus sampling is used in prenatal diagnosis, enabling to detect fetal genetic abnormalities. Its advantages include the possibility of performing the procedure during the first trimester of pregnancy relatively fast result, risk of miscarriage comparable to that in case of amniocentesis.
