Accepted Answer

Amniocentesis involves sampling the fetal cells that are present in the amniotic fluid surrounding the fetus. This is done by inserting a needle through the mother's abdomen and into the amniotic sac to collect a sample of the fluid. The fetal cells are then analyzed for genetic abnormalities or other conditions.
