Chorionic villus sampling is also referred to as CVS.

Transabdominal: In this method, a long thin needle is inserted through the abdomen in your placenta. Then the needle collects a sample of tissue and then it is taken out. This is same as amniocentesis.
Transcervical: In this procedure a thin catheter is inserted into the cervix through placenta. The cells are taken into the catheter. This is a most common method of chorionic villus sampling.
