Final answer:
Chorionic Villus Sampling is done between the 11th and 14th weeks of gestation and can reveal genetic disorders like Down syndrome and cystic fibrosis, as well as the baby's sex and Rh blood type.
Step-by-step explanation:
Chorionic Villus Sampling (CVS) is a prenatal test typically performed between the 11th and 14th weeks of gestational age (GA).
This procedure involves collecting a small sample of cells from the placenta, specifically from the chorionic villi, which are tiny, finger-like projections that attach the placenta to the uterine wall and share the baby's genetic makeup.
CVS can determine genetic and chromosomal conditions, such as Down syndrome, cystic fibrosis, and Tay-Sachs disease. It can also reveal the baby's sex and Rh blood type. Due to its invasive nature, CVS carries some risks, including miscarriage, and should be discussed with a healthcare provider.
