A needle is inserted through the abdominal wall with ultrasound guidance, and a sample of the chorionic villi is removed. Cramping may be felt with this approach as well

Using ultrasound as a guide, a thin tube is passed from the vagina into the cervix. Gentle suction removes a sample of tissue from the chorionic villi. Some women experience cramping with the removal.

This alternative to an amniocentesis removes some of the chorionic villi and tests them for chromosomal abnormalities, such as Down syndrome. Its advantage over an amniocentesis is that it can be performed earlier, allowing more time for expectant parents to receive counseling and make decisions. The risks of CVS are higher than with amniocentesis so the risks and benefits of the test must be weighed.

Chorionic villi are tiny finger-like units that make up the placenta (a disk-like structure that sticks to the inner lining of the uterus and provides nutrients from the mother to the fetus through the umbilical cord). They have the same chromosomes and genetic makeup as the fetus.

When Should I Have This Test?
Amniocentesis is usually performed between 15 and 20 weeks. How Is the Test Performed? While watching with an ultrasound, the doctor inserts a needle through the abdominal wall into the uterus to remove some (about 1 ounce) of the amniotic fluid. Some women report that they experience cramping when the needle enters the uterus or pressure while the doctor retrieves the sample. The doctor may check the fetus' heartbeat after the procedure to make sure it's normal. Most doctors recommend rest for several hours afterwards. The cells in the withdrawn fluid are grown in a special culture and then analyzed (the specific tests conducted on the fluid depend on personal and family medical history). |

This test can be very accurate — close to 100% — but only certain disorders can be detected. The rate of miscarriage with this procedure is between 1 in 300 and 1 in 500. It also carries a low risk of uterine infection, which can also cause miscarriage, leakage of amniotic fluid, and injury to the fetus

Late in the pregnancy, this test can reveal if a baby's lungs are strong enough to allow the baby to breathe normally after birth. This can help the health care provider make decisions about inducing labor or trying to prevent labor, depending on the situation. For instance, if a mother's water breaks early, the health care provider may want to try to hold off on delivering the baby as long as possible to allow for the baby's lungs to mature. Other common birth defects, such as heart disorders and cleft lip and palate, can't be determined using this test.
