Quizplus · Accepted Answer

The test being referred to is chorionic villus sampling (CVS), which is usually performed between the 8th and 11th week of pregnancy. While it can provide genetic information about the fetus, it carries a risk of miscarriage that is estimated to be between 1 in 100 and 1 in 200 pregnancies. The other options listed (amniocentesis, ultrasound sonography, and first-trimester screen) do not carry as high a risk of miscarriage as CVS.
