Prenatal genetic testing is an optional diagnostic testing that is done during pregnancy to check for any birth abnormalities or genetic disorders present in the fetus. Spina bifida, down syndrome, and trisomy 13 are some of the genetic disorders that can be detected during invasive prenatal testing.
If you're pregnant and have a family history of genetic disorders, then you can consult with your healthcare provider to include invasive prenatal testing in your routine prenatal tests. Dr. Vinayak Das is a well-known gynecology and fetal medicine specialist who can perform this medical procedure precisely to let you know that your baby has no defects or next treatment if any abnormalities are detected.
Amniocentesis is a medical procedure that is guided by an ultrasound. During this method, a small amount of amniotic fluid is collected by a syringe from the amniotic sac of the mother. This fluid is collected because it contains various cells of the fetus which are necessary for genetic testing.
Amniocentesis is normally done during the 15th week of pregnancy which helps in detecting congenital and chromosomal disabilities. This is normally a painless procedure but some of the patients may suffer from certain side effects such as cramping and leakage of amniotic fluid.
CVS is another ultrasound-assisted procedure in which a small sample of chorionic villi is collected. Chorionic villi are small projections in the placental tissue that contains important genetic material of the fetus.
The preferable time to undergo this genetic testing is during the 11 and 14th weeks. The heartbeat and movements of the fetus are checked after completing the CVS procedure. You can visit a reputed clinic to undertake the prenatal tests in Siliguri which will provide precise results of the health condition of the baby.
The decision of undergoing invasive prenatal testing is optional. Your healthcare provider can recommend you these tests if the results of your ultrasound were abnormal, where these tests will provide a briefer idea about the health of the fetus.
Some of the other prominent reasons for doing the tests include a family history of genetic disorders, multiple miscarriages, advanced maternal age, and improper reports of genetic screening tests. Dr. Vinayak Das is an experienced fetal medicine doctor who will guide you through further treatments if any abnormalities are detected.

SPECIALIST IN FETAL MEDICINE & HIGH RISK PREGNANCY.
You have various options for invasive diagnostic tests and screening tests for prenatal testing. Some of the common screening tests include non-invasive prenatal testing, ultrasound, and carrier screening whereas, CVS and amniocentesis are the common diagnostic tests.
Invasive prenatal testing has high accuracy rates in detecting genetic disorders such as Down syndrome and Patau syndrome. However, you must also consider the fact that it is not 100% precise.
Yes, miscarriage is the major risk of CVS and amniocentesis since it is a highly invasive test procedure. The tests which are done before 15 weeks of pregnancy increase the chances of miscarriage more.
You must undertake invasive prenatal testing if you have the risk of transferring any Mendelian disorder to the fetus. Additionally, if any structural anomalies have been detected during ultrasound then also the doctor may recommend prenatal testing.
No, ultrasounds are generally painless and non-invasive that only pass high-frequency sound waves to the fetus. This helps in recording and imaging the fetus to check its health conditions and movement.
