If CVS is being carried out to test for a specific genetic condition, the cells in the sample can also be tested for this.

This will tell you whether a chromosomal condition, such as Down's syndrome , Edwards' syndrome or Patau's syndrome , has been found. If rarer conditions are also being tested for, it can take 2 to 3 weeks or more for the results to come back. You can usually choose whether to get the results over the phone or during a face-to-face meeting at the hospital or at home.

Genes are parts of DNA passed down from your mother and father. Normally, people have a total of 46 chromosomes. Chorionic villi contain the same chromosomes as an unborn baby.

So, a CVS test can show if a baby has an extra chromosome or a missing or damaged chromosome. These chromosome differences can cause serious health problems. CVS is a prenatal diagnostic test, which means it can almost always tell for sure whether an unborn baby has a chromosome disorder. This is different than a prenatal screening test, which only shows whether a baby has an increased risk of a serious health problem.

CVS testing is used to diagnose chromosome problems or other genetic diseases in an unborn baby. These include:. CVS testing is very accurate and can be done early in pregnancy, between the 10th and 13th week. But it can only diagnose certain genetic diseases. Different tests, including an alpha-fetoprotein AFP blood test , are used to screen for or diagnose these and other birth defects. You may need CVS testing if you are at higher risk for having a baby with a chromosome disorder.
