Amniocentesis is one of the most reliable prenatal diagnostic tests used to confirm chromosomal or genetic abnormalities in a developing baby. It helps parents make informed decisions with clarity and confidence.
At Shree Diagnostics, Howrah, we provide expert-guided amniocentesis with complete safety, hygiene and specialist support.
What is Amniocentesis?
Amniocentesis is a procedure in which a small amount of amniotic fluid (the fluid surrounding the baby inside the uterus) is collected using a thin needle under continuous ultrasound guidance.
This fluid contains fetal cells and important biochemical substances, which are tested to diagnose:
- Chromosomal abnormalities
- Genetic disorders
- Neural tube defects
- Certain infections
- Fetal lung maturity (in late pregnancy, rarely required today)
Amniocentesis is a diagnostic test, meaning its results are highly accurate and not screening-based.
When is Amniocentesis Recommended?
Doctors may suggest amniocentesis when:
✔ NIPT Test is positive or high-risk
✔ Double Marker / Quadruple Marker Test shows abnormal results
✔ NT Scan shows increased nuchal translucency
✔ Previous pregnancy had a chromosomal disorder
✔ Family history of genetic diseases
✔ Parents are carriers of inherited disorders
✔ Mother’s age is ≥ 30 years (higher risk of chromosomal abnormalities)
✔ Structural abnormalities seen in ultrasound
✔ To test for infections (rare)
This test is usually performed between 15–20 weeks of pregnancy.
What Amniocentesis Can Detect
✔ Down Syndrome (Trisomy 21)
✔ Edwards Syndrome (Trisomy 18)
✔ Patau Syndrome (Trisomy 13)
✔ Neural Tube Defects (e.g., spina bifida)
✔ Genetic & Metabolic Disorders
Examples:
- Thalassemia
- Sickle cell disease
- Cystic Fibrosis
- Muscular dystrophy
✔ Sex chromosome abnormalities
- Turner syndrome
- Klinefelter syndrome
✔ Infection testing (CMV, Toxoplasmosis – if required)
How is the Procedure Performed?
The procedure is done by an experienced specialist under sterile conditions:
- Ultrasound scanning – to locate the baby and safe pocket of fluid
- Skin cleaning – maintaining complete antiseptic hygiene
- Thin needle insertion – quick and guided carefully via ultrasound
- Collection of 15–20 ml of amniotic fluid
- Monitoring – the baby’s heartbeat and mother’s condition are checked
The procedure usually takes 10–15 minutes, and most mothers feel only mild pressure.
Is Amniocentesis Safe?
Amniocentesis is considered very safe when done by trained specialists under proper guidance.
However, like any medical procedure, it carries minimal risks such as:
- Mild pain or cramping
- Very small chance of infection
- Very low risk of miscarriage (less than 0.1% with modern techniques)
At Shree Diagnostics, we maintain strict safety protocols to ensure maximum care.
Amniocentesis vs NIPT: What’s the Difference?
| Feature | NIPT | Amniocentesis |
|---|---|---|
| Type | Screening | Diagnostic |
| Accuracy | Very high (99%) | 100% for chromosomal disorders |
| Risk | None | Minimal |
| When done | From 10 weeks | 15–20 weeks |
| Detects | Risk level | Definitive genetic and chromosomal results |
If NIPT or Marker tests are positive, amniocentesis is the final confirmatory test.
After the Procedure – Recovery & Care
Most patients can return home the same day. Doctors advise:
- Adequate rest for 24 hours
- Avoid heavy lifting for 1–2 days
- Report severe pain, fever, or fluid leakage (rare)
