a test done during pregnancy that involves taking a small sample of tissue from the developing pregnancy to check for genetic issues in the baby
Chorionic villus sampling (CVS) is a test done during pregnancy to examine the genetic health of a developing baby. It involves taking a small sample of tissue from the placenta, which is the organ that provides nutrients and oxygen to the baby. This tissue, known as chorionic villi, contains the same genetic formation as the baby. During the procedure, a thin tube is inserted through the vagina and cervix or a needle is inserted through the abdomen to collect the tissue sample. The sample is then analyzed for genetic disorders or chromosomal abnormalities, such as Down syndrome. CVS is typically done between the 10th and 13th weeks of pregnancy and can provide early information about the baby's health, but it also involves some risks, including a small chance of miscarriage.
