Another test that can be performed during a pregnancy is called Chorionic Villus Sampling. This is a procedure that occurs early on in pregnancy in which "a thin tube is inserted into the uterus through the vagina, or a hollow needle is inserted through the abdominal wall" (Berk, 44) of an expectant mother. A "small plug of tissue is removed from the end of one or more chorionic villi, the hairlike projections on the chorion, the membrane surrounding the developing organism" (Berk, 44). This is a wonderful procedure because it can be performed as early as 9 weeks after conception and parents would receive the results very quickly, within about 24 hours (Berk, 44). Chorionic Villus Sampling or CVS "can detect almost every chromosomal abnormality known to man. It can detect Down syndrome, Turner syndrome and other sex chromosome anomalies, trisomy 13 and trisomy 18 among others. Hundreds of genetic defects can also be identified using CVS. The test can detect Tay-Sachs disease, sickle cell disease and cystic fibrosis" (Chorionic Villus Sampling). The CVS procedure is also more accurate and less painful than an
