CVS (Chorionic Villus Sampling) is a pregnancy test, which is used to check the baby for biochemical or genetic abnormalities.

This sample is removed by using a thin needle inserted through the abdomen. Then that tissue would be examined in the laboratory.

Unlike other test during pregnancy such as ultrasound and scanning, CVS pregnancy test is not a general monitoring of the baby’s health but an essential test for certain abnormalities, like Cystic fibrosis or Down syndrome. The risk of abortion followed by the CVS pregnancy test is one in 100, so it is very important to understand the complication, risks and benefits before going to take the CVS test.

In very rare cases this test may defect the baby’s toes or fingers, especially this may occur if the CVS test was done earlier than 9 weeks. Due to this risk, generally 10 weeks is the earliest advised time to perform the CVS test.
