Pregnancy is a journey brimming with joy, anticipation and questions. One such question that may arise for some expecting parents is about Amniocentesis. Expectant parents frequently express curiosity about this prenatal evaluation. The best doctor at the leading amniocentesis testing center in Kolkata discusses its purpose and implications.

What is Amniocentesis?


Amniocentesis is a prenatal test that involves withdrawing a small amount of amniotic fluid surrounding the developing foetus. This fluid contains fetal cells, which offer valuable insights about the baby's health and potential genetic conditions.


Why is it Done?


Amniocentesis is not routinely performed for all pregnancies. It is primarily offered when there is an increased risk of:


  • Chromosomal abnormalities: This includes conditions like Down syndrome, Edwards syndrome and Patau syndrome.


  • Genetic disorders: Amniocentesis can detect specific genetic conditions like thalassemia ,cystic fibrosis, Tay-Sachs disease and sickle cell anaemia, especially if there's a family history.


  • Foetal infections: In rare cases, the test may be used to check for viral infections in fetus  like Cytomegalovirus (CMV) , Rubella , Varicella (Chickenpox ).


Who should opt for Amniocentesis?


Several factors might increase the chance of being offered an amniocentesis:


  • Maternal age: As maternal age increases ( after 35 ), the risk of specific chromosomal abnormalities also rises.


  • Abnormal screening tests: If earlier prenatal screening tests like Double marker Quadruple screen or NIPT (non-invasive prenatal testing) indicate a higher risk, Amniocentesis can provide definitive results.


  • Family history: Having a family member with a genetic condition makes Amniocentesis a potential option.


  • Previously affected pregnancies: If a previous pregnancy was affected by a genetic condition. It is advisable for patients to undergo this test at the best amniocentesis testing center in Kolkata in subsequent pregnancies.


The Procedure:


Amniocentesis is usually performed after 15 weeks of pregnancy. Using ultrasound guidance, a very fine  needle is inserted through the abdomen and uterus to draw a small amount of amniotic fluid. The procedure is typically quick and minimally invasive.


Results and Implications:


The extracted fluid is sent for analysis, which can take few days to several weeks , depending on type of genetic testing needed. Results might reveal chromosomal abnormalities, genetic disorders or foetal infections. If a condition is detected, parents can make informed decisions regarding their pregnancy and seek appropriate counselling and support. 


Usually such procedures are painless and risk free , but may carry a 0.3% (3:1000) chance of miscarriage.


Whether or not to undergo Amniocentesis is an informed choice and parents must carefully consider the benefits alongside their doctor's guidance. Weighing factors like personal anxieties, family history and the potential impact of the results is essential. 


Amniocentesis plays an essential role in prenatal care, offering valuable information about the foetus's health and potential genetic concerns. While unsuitable for all pregnancies, it empowers parents with knowledge and helps them make informed decisions about their journey.
