Chorionic villus sampling (CVS) is a prenatal diagnostic test that can detect chromosomal abnormalities or genetic disorders in a developing fetus as early as nine weeks into pregnancy. CVS involves taking a small sample of cells from the placenta, which can then be tested for genetic abnormalities. This test provides quick results, usually within 24-48 hours, making it a good choice for cases where early diagnosis is important. Ultrasound and genetic counselling are not diagnostic tests, and amniocentesis is typically performed later in pregnancy around 16-20 weeks.
