Chorionic Villus Sampling (CVS): Procedure and Risks

Every woman who is pregnant starts her term with a test and the series of these tests continue till the time the baby is born. While there are many tests which are done for diagnosis there are others which are known to be screening tests. One such test is the CVS or Chorionic Villus Sampling.

Chorionic Villus Sampling is known as a prenatal test which helps to detect any chromosomal abnormalities like for example the Down syndrome. Apart from this, this test also helps to detect any other abnormalities which might occur. The Chorionic Villus Sampling Procedure is not a hard one. When you are asked to go in for the test, the doctor collects the cells from your placenta which is also called as the chorionic villi and these are then sent to the lab for further diagnosis.

Not every pregnant woman is asked to go in for the CVS test. This test is only recommended for those women who have a risk of miscarriage or have had any genetic or chromosomal problems. This is only asked for when the initial prenatal test has some abnormalities. The CVS tests can be done even during the 10 weeks to 13 weeks of pregnancy.

While undergoing the test is simple and easy, many also believe that there are some Chorionic Villus Sampling Risks. While the news about the miscarriage after the CVS test is true but the chances for the same are very less and this can be anything from 1 in 100 or 200. But there are also some older studies which have stated that the procedure of CVS have indeed caused some damage to the fingers or the toes of the babies and this is more possible when the test is done before 9 weeks of pregnancy. The very recent studies do state that such risks do not occur when the tests are done after 11 weeks of pregnancy.

Before the CVS test is done, you will have to undergo an ultrasound as it helps the doctor to see how you are progressing and if they would be able to get the right sample for the test. You need to make sure that you have a full bladder so as to get the good view of your uterus. The main goal of this test is to obtain the tiny tissue of your placenta which is then sent to the lab for further study. You can be assured that the amniotic sac will not be disturbed in this process and even the doctor would check the heartbeat of your baby after the sample has been collected. So, you can be assured that you baby is all safe and this would not harm him/her.

You can check with your insurance provider if you are entitled for cover for the CVS test; if not your can check for the Chorionic Villus Sampling Cost with the doctor. A number of testing centers also ask for the woman to undergo a counseling session with a genetic counselor before you go in for the test.

Hi, I’m Stephanie. I graduated college with a business degree and a minor in biology. I met my husband at a business convention and was happily marriage and pregnant within the first two years after saying the words “ I do”. Jennifer is the eldest of the three. Being pregnant with her, my first, I researched everything pregnancy related and read nearly every book. Giving birth to Anthony and Matty seemed more natural and less stressful the third time around. I’m happy to share what knowledge I have gathered and learn new things from other mothers. From morning sickness to Anencephaly, or potty training to thumb sucking, I have books and resource guides to share.
