Which procedure is used to detect chromosomal and genetic abnormalities in the fetus by removing cells from a layer of the placenta?

Chorionic villus sampling (CVS), or chorionic villus biopsy, is a prenatal test that involves taking a sample of tissue from the placenta to test for chromosomal abnormalities and certain other genetic problems.

What does the amniocentesis test look for?

Amniocentesis is a prenatal procedure that your doctor may recommend you have during pregnancy. The test checks for fetal abnormalities (birth defects) such as Down syndrome, cystic fibrosis or spina bifida. In most cases, the results are normal. Amniocentesis is performed between 16 and 20 weeks into the pregnancy.

How does an amniocentesis work?

What Is Amniocentesis? Amniocentesis is a prenatal test in which a small amount of amniotic fluid is removed from the sac surrounding the fetus for testing.

Is CVS riskier than amniocentesis?

Compared with a second trimester amniocentesis, transcervical CVS carries a higher risk of pregnancy loss, although the results are quite heterogeneous. One study compared transabdominal CVS with second trimester amniocentesis and found no significant difference in the total pregnancy loss between the two procedures.

Why is amniocentesis better than CVS?

For example, CVS is generally done earlier in pregnancy than amniocentesis and is particularly advantageous for detecting certain genetic conditions. Another important factor is the risk for miscarriage, which has been attributed to 0.5%-1.0% of CVS procedures and 0.25%-0.50% of amniocentesis procedures.

What week do you get an amniocentesis?

Amniocentesis is usually carried out between the 15th and 20th weeks of pregnancy, but you can have it later if necessary.
