Chorionic villus sampling (CVS) is the prenatal diagnostic test that involves removing a small sample of the placenta. This test is usually performed between weeks 10 and 13 of pregnancy and can help diagnose chromosomal abnormalities and genetic disorders in the fetus. Ultrasound sonography is a non-invasive imaging technique that uses sound waves to create images of the fetus in the womb. Amniocentesis involves collecting a sample of amniotic fluid from the sac surrounding the fetus, and maternal blood sampling tests for certain markers in the mother's blood to assess the risk of fetal abnormalities.
