The full form of CVS is Chorionic Villus Sampling. Doctors use a prenatal diagnostic procedure to detect certain genetic abnormalities in a developing fetus. It is an important medical test that provides valuable information to expectant parents and healthcare professionals.

During pregnancy, the placenta develops in the uterus to provide vital nutrients and oxygen to the growing fetus. The placenta contains small finger-like projections called chorionic villi, which are formed from the same fertilized egg as the fetus. These chorionic villi contain genetic material that can be analyzed to determine if the fetus has certain genetic conditions or chromosomal abnormalities.
Healthcare professionals typically perform Chorionic Villus Sampling between the 10th and 12th weeks of pregnancy. Although the exact timing may vary depending on the healthcare provider’s recommendations. The procedure involves collecting a small sample of chorionic villi from the placenta. There are two main methods of CVS: transabdominal and transcervical. The transabdominal method involves inserting a thin needle through the mother’s abdomen and into the uterus to collect the sample. The transcervical method involves inserting a small catheter through the cervix to reach the placenta.
Once the sample is obtained, it is sent to a laboratory for analysis. Various techniques can examine the genetic material in the chorionic villi, such as chromosomal analysis or DNA testing. These tests can provide information about the presence of certain genetic disorders. Such as Down syndrome, cystic fibrosis, or Tay-Sachs disease.

It is important to note that CVS can provide valuable information about the health of the fetus. It is an invasive procedure and carries a small risk of complications, including miscarriage. Women who have an increased risk of having a baby are usually offered prenatal care. Or with a genetic condition or those who have had abnormal prenatal screening results.
Chorionic Villus Sampling (CVS) is a prenatal diagnostic procedure that involves collecting a sample of chorionic villi from the placenta to detect genetic abnormalities in a developing fetus. It is an important tool for providing expectant parents and healthcare professionals with valuable information about the health of the unborn child. However, it is essential to discuss the potential risks and benefits of CVS with a healthcare provider before deciding to undergo the procedure.
