How is a cvs proceedure done?

Chorionic villus sampling (CVS) is a prenatal test performed to diagnose genetic conditions in a fetus. It typically involves inserting a thin tube (catheter) through the cervix or a needle through the abdominal wall to obtain small samples of placental tissue, known as chorionic villi. The procedure is usually done between the 10th and 13th weeks of pregnancy and can be performed under ultrasound guidance to ensure accuracy. Following the procedure, the tissue sample is analyzed for chromosomal abnormalities or genetic disorders.
