Introduction:
A CVS test is a medical diagnostic tool used to detect genetic disorders in a fetus. It is a procedure that can be used to detect the presence of chromosomal abnormalities in the fetus.
CVS test results can be used to help parents make informed decisions about the health of the fetus. This article will discuss the procedure of CVS testing, the benefits and risks associated with it, and the interpretation of CVS test results.
What is the CVS Test in Pregnancy?
A prenatal test called chorionic villus sampling (CVS), also known as chorionic villus biopsy, involves collecting a sample of tissue from the placenta to determine whether the fetus has a chromosomal or genetic disorder such as Down’s syndrome, Edwards’ syndrome, or Patau’s syndrome.
A CVS is ideal between 11 and 13 weeks of pregnancy. The CVS test results could turn up as positive or negative and the fetal specialist will guide you throughout.
What if the CVS test is negative?
As a CVS test also known as chorionic villus sampling is used to find out if the fetus has any abnormalities, a negative CVS test results means that the fetus does not have any chromosomal abnormalities.
Should I worry about CVS’s negative result?
The negative outcome of the CVS test results has nothing to worry about, as it means that the baby is pretty healthy and there is no sign of any chromosomal abnormality.
Can chorionic villus be wrong?
Although chorionic villus sampling is 99% accurate in most cases, there is still a 1% chance of it going wrong.
However, the healthcare provider will confirm the abnormality only after doing a series of confirmatory tests, which will rule out whether the baby has any abnormalities or not.
Is a CVS test necessary?
Although CVS isn’t mandatory for all pregnant mothers, it is recommended, especially for:
- Pregnant women over the age of 37
- Pregnant women with a family history of abnormalities
- A pregnant mother who already has another child with an abnormality
Can CVS test cause miscarriage?
The miscarriage rate after a CVS test is pretty low (1 % ). It is said that 1 in 200 to 300 women who have the CVS test done are prone to have miscarriage.
But the rate increases if the women is carrying multiple babies at once ie. twins or triplets, etc.
Miscarriage can happen anywhere between 3 days to 2 weeks after the procedure. It is said that one can do nothing to prevent the miscarriage.
Amniocentesis which is a similar scanning process that is carried out during 15 to 18 weeks of pregnancy has the similar miscarriage outcome.
