Chorionic villus sampling (CVS) is a prenatal technique that involves taking a sample of cells from the chorionic villi, which are tiny finger-like projections that form the placenta and begin to form the umbilical cord. This sample can be used to examine the genetic status of the fetus for abnormalities or disorders. Amniocentesis involves taking a sample of the amniotic fluid, which surrounds the fetus, and is typically used to screen for genetic disorders or to check the health of the fetus. Alpha-fetoprotein (AFP) screening is a blood test that measures levels of a protein produced by the fetus to screen for some fetal abnormalities. Ultrasound involves using high-frequency sound waves to create an image of the fetus and is used to check on the growth and development of the fetus. However, it does not involve taking samples of cells for genetic testing.
