What is the chorionic villus sampling CVS Test?

You might be given a CVS test when you are pregnant to determine whether your unborn child has a chromosomal or genetic disorder like Down's syndrome, Edwards syndrome, or Patau's syndrome.

It entails taking a small portion of cells from the placental, the organ that connects the mother's blood flow with the blood flow of the unborn child, and analyzing them. A structure in the uterus called the placenta transports blood and nutrition from the mother to the foetus.

The chorionic villi are microscopic finger-like extensions of placental tissue that have the same genetic makeup as the developing foetus. Based on the family history and the accessibility of lab testing at the time of the surgery, testing may be possible for further genetic abnormalities and illnesses.

When is a chorionic villus sampling CVS performed?

Between the tenth and twelfth weeks of pregnancy, CVS is typically performed. CVS does not reveal information about neural tube problems such as spina bifida, in contrast to amniocentesis (another type of prenatal test). To check for neural tube abnormalities, women who have CVS must additionally have a follow-up blood test around 16 and 18 weeks of pregnancy.

Two different CVS techniques exist:

1. Transcervical. To acquire the tissue sample in this operation, a catheter is introduced through the cervix into the placenta.
2. Transabdominal. To acquire the tissue sample in this process, a needle is introduced into the placenta through the uterus.

Amniocentesis is a related treatment that can be used to identify chromosomal and genetic abnormalities.

What does chorionic villus sampling CVS detect?

Certain genetic illnesses, such as chromosomal disorders, can be found with the aid of CVS. Foetal DNA is stored in these cell structures. CVS can identify chromosomes that are extra, missing, or that have had severe structural alterations. Birth abnormalities and other issues may result from these genetic alterations.

CVS tests for the following conditions:

1. Trisomy 21 or Down syndrome
2. Cystic fibrosis
3. Sickle cell illness
4. Tay-Sachs illness
5. Either Edward syndrome or trisomy 18

Many women with CVS will experience a "normal" outcome. This indicates that the baby did not have any of the conditions that were tested for. However, because the test only looks for illnesses brought on by specific genes, it cannot exclude illnesses that were not examined.
