Question

Quizplus · Accepted Answer

The procedure described is chorionic villus sampling (CVS). In amniocentesis, cells are collected from the amniotic fluid surrounding the fetus, not the membranes. Ultrasound is a imaging technique that allows visualization of the fetus but does not collect cells for testing. Intra-uterine probe testing is not a commonly used term in prenatal testing.
