What diseases or disorders can chorionic villus sampling (CVS) help identify, and how accurate is the test?

ANSWER

Chorionic villus sampling (CVS) can help identify such chromosomal problems as Down syndrome or other genetic diseases such as cystic fibrosis, Tay-Sachs disease, and sickle cell anemia. CVS is considered to be 98% accurate in diagnosing defects in chromosomes. It also can tell the sex of the fetus, so it can identify disorders that are linked to one sex, such as certain types of muscular dystrophy that happen most often in males. CVS doesn’t detect open neural tube defects like spina bifida.
