Chorionic Villus Sampling (CVS)

What Is Chorionic Villus Sampling
Chorionic villus (CVS) sampling is a procedure that includes placement of a needle through the abdominal wall or placement of a soft rubber catheter through the cervical canal. This is used to sample pieces of the villi, or placenta, for genetic testing. CVS has applications for early genetic testing between the 9th and 14th weeks of pregnancy, and is generally performed only in certain special circumstances.
