Approximately 120,000 babies are born each year with a genetic defect, leading to one in five children dying within their first year of life. This is why genetic testing is an essential component of effective pre-natal care and a valuable means of identifying potential health issues for your child early. One such diagnostic method is chorionic villus sampling.
This test takes a tissue sample from the placenta to determine whether your baby may have chromosomal abnormalities or other genetic problems. It’s typically performed between the 10th and 12th weeks of pregnancy and is followed by a blood test between weeks 16 and 18 to check for neural tube defects.
Chorionic villus sampling may be conducted in two ways. The first, referred to as transcervical chorionic villus sampling, obtains a tissue sample from the placenta through a catheter inserted in your cervix. The second method, transabdominal sampling, obtains this sample through a needle inserted through your abdomen and uterus.
If you have a family history of genetic disorders, you may be recommended to undergo this procedure. It may also be recommended if your other genetic and diagnostic tests have shown abnormal results or if you will be 35 years of age or older by your pregnancy due date.
If your doctor does not make a recommendation for you to receive this test, you may still choose to do so. However, this procedure is invasive and comes with some risks, such as cramping, bleeding, infection, preterm labor, and rarely, more serious problems such as infant limb defects or miscarriage.
You should discuss the benefits and risks of chorionic villus sampling with a doctor. You can schedule an appointment with an OB/GYN at Flushing Hospital Medical Center’s Women’s Health Department by calling (718) 670-5702.
