CVS Pregnancy Test

CVS Pregnancy Test

Nowadays there are lot of ways to diagnose even the most dangerous and serious diseases. One of them is CVS – Chorionic villus sampling. It is a prenatal test that detects chromosomal abnormalities such as Down syndrome and other genetic disorders (e.g. cystic fibrosis).

In the process of the test doctor takes cells from the placenta (the genetic material in these cells is the same as that in the baby's cells), where it attaches to the wall of the uterus. Afterwards the results are sent into laboratory to be proved.
The main advantage of CVS is the possibility to know the results earlier than by other familiar tests. The woman can be tested already between 11 and 12 weeks of pregnancy. The results usually obtain 10 days.

The risk of CVS is the possibility of miscarriage.

CVS pregnancy test is recommended to:

  1. Parents who are at increased risk of having a baby with some genetic disorders;
  2. Women who are older than 37;
  3. Parents who have already had a child/children with some genetic disorders;
  4. Mothers who have health problems that can affect the baby’s health;
  5. A man and a woman who carry an abnormal gene;
  6. Women whose ultrasound test results showed a possible abnormality;
  7. Parents who are anxious about the health of their baby.

There is 2 ways to make a CVS test:

  • Transcervical CVS – a catheter goes through your vagina and cervix into the placenta;
  • Transabdominal CVS – tiny flexible needle goes through your belly into the placenta.

Amniocentesis is an alternative to CVS pregnancy tests. It is done by removing a few of amniotic fluid through a thin needle inserted in the abdomen. The cells found in the fluid are to be examined for chromosomal abnormalities. In some situations it is more appropriate than CVS. It can’t show the results in early pregnancy, but it gives more accurate results. The miscarriage of amniocentesis estimates at one in 250, while by CVS – one in 100.
