Question: Should I Get CVS Or Amnio?

Why is amniocentesis a more widely used test than CVS?

When testing for chromosomal abnormalities resulting from advanced maternal age, CVS may be more acceptable than amniocentesis to some women because of the psychological and medical advantages provided by CVS through earlier diagnosis of abnormalities..

Does CVS hurt more than amnio?

Amniocentesis can detect certain things that CVS can’t, including neural tube defects like spina bifida, birth defects, and Rh incompatibility. Possible risks, like miscarriage, are slightly higher for CVS, and the procedure is slightly more painful.

Should I go for amniocentesis?

Who should have an amniocentesis? Doctors and genetic counselors generally recommend the test for any woman who is at increased risk of having a baby with a chromosomal abnormality or neural tube defect.

Is CVS worth the risk?

A CVS test has some risks. You’ll have to weigh the benefit of knowing if something might be wrong with your baby against the risks of having the test. There is a small chance that the test may cause you to have a miscarriage. This means that you could lose your baby after you have the test.

What amniocentesis Cannot detect?

Because ultrasound is performed at the time of amniocentesis, it may detect birth defects that are not detected by amniocentesis (such as cleft palate, cleft lip, club foot, or heart defects). There are some birth defects, however, that will not be detected by either amniocentesis or ultrasound.

Is amnio test 100 accurate?

Amniocentesis can be very accurate — close to 100% — but only some disorders can be detected. The rate of miscarriage with this test is between 1 in 300 and 1 in 500. It also carries a low risk of uterine infection, which can also cause miscarriage, leakage of amniotic fluid, and injury to the fetus.

What are pros and cons of CVS and amniocentesis?

The advantage of CVS is that you can get this test five to 10 weeks earlier than amniocentesis. The disadvantage is that it can’t detect neural tube defects, such as spina bifida. CVS is relatively safe. But it is an invasive procedure, and it poses a risk of miscarriage slightly higher than amniocentesis.

Is amnio or CVS safer?

Second trimester amniocentesis is safer than early amniocentesis or transcervical CVS, and is the procedure of choice for second trimester testing. Transabdominal CVS should be regarded as the procedure of first choice when testing is done before 15 weeks’ gestation.

Can a CVS test for Down syndrome be wrong?

CVS can help identify such chromosomal problems as Down syndrome or other genetic diseases such as cystic fibrosis, Tay-Sachs disease, and sickle cell anemia. CVS is considered to be 98% accurate in the diagnosis of chromosomal defects.

How painful is an amniocentesis?

Amniocentesis is not usually painful, but you may feel uncomfortable during the procedure. Some women describe experiencing a pain similar to period pain or feeling pressure when the needle is taken out.

What is the alternative to amniocentesis?

A new method of detecting genetic defects in the womb is fast becoming an alternative to the the more common amniocentesis. The procedure, chorionic villus sampling (CVS), can be performed in the eighth or ninth week of pregnancy. Amniocentesis is usually performed in the 15th week.
