CVS (chorionic villus sampling) -- a test where a small bit of the chorion surrounding the baby is sampled with a tube going up through the cervix. Testing this can reveal genetic problems with the baby and tell its sex.
How is performed?
may be offered to women who are at increased risk for chromosomal abnormalities or have a family history of a genetic defect that is testable from the placental tissue.
CVS is a diagnostic test usually performed at 10 to 12 weeks of pregnancy for women who have had an abnormal screening test. In comparison, amniocentesis is usually performed at 15 to 18 weeks.

CVS increases the risks of fetal loss by about 1.2 percent over the risk without the procedure. There have been concerns about the procedure itself causing malformations of legs and arms. This risk seems to be about 0.

An alternative to amniocentesis that can be done earlier in the pregnancy. It is a biopsy of the placenta that is used to check for genetic abnormalities in the fetus.

How does CVS works?
A doctor will take a tiny piece of tissue from your placenta via a needle inserted into your tummy. There is a very small risk of miscarriage associated with this test, estimated at 1-2 percent.
(Chorionic villus sampling) is one test that detects chromosome and other genetic abnormalities, usually between the 9th and 14th weeks of pregnancy. Learn more about prenatal screening and diagnostic testing.
