Prenatal genetic testing has transformed pregnancy care by providing a clearer view of an unborn child’s genetic health. Chorionic Villus Sampling (CVS) is a critical procedure that enables early diagnosis of genetic disorders. This brief overview explores its growing role in modern pregnancy care in Kolkata.
What is Chorionic Villus Sampling (CVS)?
Chorionic Villus Sampling is a prenatal test conducted between the 10th and 13th weeks of pregnancy to detect genetic conditions like Down syndrome, cystic fibrosis, and other chromosomal abnormalities. It involves taking a small sample of placental tissue (chorionic villi) for genetic analysis. In Kolkata, CVS has gained popularity due to its early detection capabilities, allowing expecting parents to make informed decisions.
Procedure and Risk Assessment
In India, CVS is performed by experienced prenatal care providers. The procedure involves inserting a thin tube through the cervix or a needle through the abdomen to collect the sample. Although highly accurate, CVS carries risks, including a small chance of miscarriage, infection, or Rh sensitization. A thorough risk assessment is crucial before undergoing the procedure. Despite these risks, the advantages of early detection often outweigh them.
Benefits and Risks of CVS
The main advantage of CVS is early and accurate results, often weeks before amniocentesis. This early insight allows parents and healthcare providers to plan and make decisions. However, the risks, such as miscarriage, should be discussed with healthcare providers to ensure informed consent.
Cost and Alternative Tests
The cost of CVS in India varies based on location and healthcare providers. In Kolkata, institutions like the Institute of Fetal Medicine offer this procedure. Other prenatal genetic tests include amniocentesis and non-invasive prenatal testing (NIPT), each with its own benefits and limitations.
Impact on Pregnancy Care
Prenatal genetic testing has reshaped pregnancy care by offering early diagnosis and more personalized approaches. CVS, with its early detection capabilities, plays a pivotal role in this transformation, providing expectant parents in Kolkata with crucial information to navigate pregnancy with clarity and confidence.
