Prenatal Diagnostic Tests

Description
Chorionic villus sampling may be performed as early as 8 weeks of gestation.
It is also done under ultrasound guidance, but the usual procedure is to insert a catheter through the vagina and cervix to collect a tissue sample from the chorionic villi.
The goal is to identify the same genetic defects as seen with amniocentesis.
The procedure may be done through the abdominal wall as with amniocentesis.
