Chorionic villus sampling (CVS) is a prenatal test that is performed between 10 and 13 weeks of pregnancy. It involves taking a small sample of tissue from the placenta, which is then tested for genetic abnormalities. CVS can be used to diagnose a variety of conditions, including Down syndrome, cystic fibrosis, and Tay-Sachs disease. There are several reasons why a woman might choose to undergo CVS. For example, she may have a family history of a genetic disorder, or she may have received abnormal results on a screening test, such as the first-trimester quadruple screen. CVS is a relatively safe procedure, but there are some risks associated with it. These risks include miscarriage, infection, and bleeding. It is important to discuss these risks with your doctor before deciding whether or not to undergo CVS. Chorionic Villus Sampling (CVS) is a prenatal test that carries risks and should only be considered under the guidance of a qualified healthcare professional. It’s crucial to seek information from trusted sources like doctors, genetic counselors, or reputable medical organizations. If you are considering CVS, it is important to speak with your doctor about your individual risk factors and to weigh the risks and benefits of the procedure carefully.
