CVS Test

CVS Test

Early prenatal diagnosis of genetic and chromosomal conditions

The journey of pregnancy is filled with joy, pain, and emotions. One of the major concerns that every pregnant woman has is related to the fetus’s health. This is where the role of Chorionic Villus Sampling (CVS) becomes significant. A CVS is a prenatal diagnostic test that is performed between 11 and 13 weeks of pregnancy to detect genetic conditions and chromosomal abnormalities. By undergoing a CVS test in Siliguri, you can rule out the presence of genetic conditions, such as Down Syndrome, Edward Syndrome (Trisomy 18), or Patau Syndrome (Trisomy 13). Overall, this test is based on removing a small tissue sample from the placenta under continuous ultrasound guidance.
