During pregnancy, every parent wants reassurance that their baby is healthy. With the advancement of technology, the NIPT Test (Non-Invasive Prenatal Testing) has become one of the most reliable screening methods to detect chromosomal conditions early—without any risk to the mother or baby.
At Shree Diagnostics, Howrah, we offer trusted and accurate NIPT testing, guided by expert radiologists and counselors for complete support.
What is the NIPT Test?
NIPT (Non-Invasive Prenatal Testing) is a simple blood test done from 10 weeks of pregnancy onwards.
It analyzes cell-free fetal DNA (cfDNA) circulating in the mother’s blood to screen for chromosomal abnormalities.
It is non-invasive, safe, and has over 99% accuracy for major chromosomal disorders.
What NIPT Can Detect
NIPT screens for the following fetal chromosomal conditions:
✔ Trisomy 21 (Down Syndrome)
Most common chromosomal condition causing intellectual disability and delayed development.
✔ Trisomy 18 (Edwards Syndrome)
Associated with severe congenital abnormalities.
✔ Trisomy 13 (Patau Syndrome)
Rare but serious condition affecting multiple organs.
✔ Sex Chromosome Abnormalities
- Turner Syndrome (45,X)
- Klinefelter Syndrome (47,XXY)
- Triple X Syndrome
- XYY Syndrome
✔ Additional Screening (Depending on Test Type)
Some advanced NIPT panels also detect:
- Microdeletions
- Certain genetic syndromes
- Fetal fraction levels
- Risk of placental dysfunction
When is NIPT Recommended?
Although any pregnant woman can choose NIPT, it is especially recommended for:
✔ Age ≥ 30 years
✔ Previous abnormal Double/Triple/Quad Marker result
✔ Previous pregnancy with chromosomal disorder
✔ Family history of genetic conditions
✔ IVF pregnancies
✔ Twin or high-risk pregnancies
✔ To avoid invasive tests like CVS or Amniocentesis when possible
Advantages of NIPT Test
1. Completely Safe
Only a blood sample from the mother—no risk to mother or baby.
2. Highest Accuracy
More than 99% accuracy for Down Syndrome and other major trisomies.
3. Early Detection
Can be done from 10th week onwards, giving early reassurance.
4. Reduces Need for Invasive Tests
Helps avoid procedures like amniocentesis unless absolutely necessary.
5. Fast & Reliable Reporting
Results typically available within 5–7 days.
How is NIPT Different from Marker Tests?
| Feature | Marker Tests | NIPT Test |
|---|---|---|
| Sample | Blood test | Blood test |
| Accuracy | 70–80% | 99%+ |
| Detects | Risk level | High accuracy chromosomal analysis |
| Weeks | 10–22 weeks | From 10 weeks |
| Risk | None | None |
| Next Step | Often followed by NIPT or diagnostic test | Diagnostic test only if positive |
NIPT = Most accurate first-line screening.
Marker tests + NT Scan still remain important for structural evaluation and complete assessment.
What NIPT Cannot Detect
NIPT is a screening test, not a diagnostic test.
It cannot replace:
❌ Detailed fetal anomaly scan
❌ Ultrasounds for structural defects
❌ Confirmation tests (CVS/Amniocentesis) if NIPT is positive
Ultrasound scans like NT Scan, Fetal Echo, Anomaly Scan are still essential.
