Quizplus · Accepted Answer

Chorionic villus sampling (CVS) is a procedure in which cells are collected from the chorionic villi, the small finger-like projections in the placenta that provide nutrients to the developing fetus. These cells are then tested for genetic abnormalities. In contrast, amniocentesis involves collecting cells from the amniotic fluid surrounding the fetus, while intra-uterine probe testing and ultrasound are imaging techniques used to visualize the developing fetus.
