How accurate is CVS testing?
CVS testing is about 99% accurate. But CVS testing does not detect how severe the condition is.
Is CVS or amniocentesis more accurate?
The difference in fetal-loss rate was estimated to be 0.8% higher after CVS compared with amniocentesis, although this difference was not statistically significant.
What is the advantage disadvantage of CVS vs amniocentesis?
The main advantage of CVS over amniocentesis is that it is performed much earlier in pregnancy, at 10 to 13 weeks, rather than 15 to 20 weeks. A disadvantage is that neural tube defects, such as spina bifida, can’t be detected.
Is CVS more risky 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.
Can CVS results be wrong?
The test can’t detect neural tube defects, such as spina bifida. There’s a 1 percent chance of getting a false positive result called a “confined placental mosaicism,” in which some of the cells cultured from the placenta contain abnormal chromosomes but the fetus is normal.
