Chorionic villus sampling (CVS) is a prenatal test that involves taking a small sample of placental tissue to test for genetic abnormalities. It can be done as early as the 10th-12th week of pregnancy and is recommended for women with a family history of genetic disorders. CVS has a higher risk of miscarriage compared to other prenatal tests, but it can provide earlier and more accurate results. Fetal monitoring and ultrasound are used to monitor the health and development of the fetus, but they do not provide genetic testing. Amniocentesis is another prenatal test that can detect genetic abnormalities, but it is typically done later in pregnancy (around 16-20 weeks).
