NT Scan in Kollam – First Trimester Screening by FMF UK Certified Expert

The most crucial early assessment of your baby's health, structural development, and chromosomal risk. Performed at 11–14 weeks by Dr. Mathew Thomas — FMF UK Certified.

What is an NT Scan?

An NT (Nuchal Translucency) Scan is a specialized ultrasound performed in the first trimester. It measures the clear (translucent) space in the tissue at the back of your baby's neck. All babies have some fluid here, but babies with chromosomal abnormalities (like Down syndrome, Trisomy 18, or Trisomy 13) or major structural defects tend to accumulate more fluid.

When is the best time for an NT Scan in Kollam?

Strictly between 11 weeks 0 days to 13 weeks 6 days. Ideally schedule between 12 to 13 weeks for the best visibility. Missing this window means the opportunity is gone.

What Does an NT Scan Detect?

While often described as a Down syndrome screening test, the NT scan is a comprehensive early structural survey. It helps detect:

  • Risk for chromosomal abnormalities (Down syndrome, Edwards syndrome, Patau syndrome)
  • Early detection of major structural defects (brain, spine, abdomen, heart)
  • Early suspicion of congenital heart defects (nasal bone, ductus venosus assessment)
  • Accurate dating of pregnancy by crown-rump length (CRL)
  • Diagnosis of multiple pregnancies and chorionicity (critical for twin management)

Why choose Dr. Mathew for your NT Scan in Kollam?

Measuring Nuchal Translucency requires precision down to a fraction of a millimeter. Dr. Mathew Thomas is an FMF UK (Fetal Medicine Foundation, London) Certified Operator for NT Scans — one of the very few in South Kerala. Only FMF-certified operators are internationally audited, ensuring your risk assessment is accurate and globally valid. 10+ years of experience in fetal imaging.

Combined First Trimester Screening

For the highest accuracy (90–95%), the NT measurement is combined with a blood test called the Dual Marker (PAPP-A and free beta-hCG) to calculate a personalized risk score. This is the internationally recommended standard for first trimester screening.

What to Expect During the Scan

The scan takes 20–30 minutes, performed transabdominally. A moderately full bladder improves image quality. The procedure is painless — you will see your baby moving on the screen. Dr. Mathew personally discusses the results with you immediately after the scan. Same-day report provided.

Frequently Asked Questions – NT Scan Kollam

When is the best time to do the NT scan in Kollam?
The NT scan must be performed between 11 weeks 0 days and 13 weeks 6 days of pregnancy. The ideal time is 12 to 13 weeks. If you miss this window (after 14 weeks), the measurement is no longer valid and cannot be repeated. Book early to secure your slot.
What does an abnormal NT scan result mean?
An elevated NT measurement raises the estimated chance of chromosomal conditions such as Down syndrome — it does not confirm a diagnosis. Further options may include NIPT, which has high sensitivity for selected conditions, or diagnostic testing such as CVS or amniocentesis. Each test has limitations, so Dr. Mathew explains the result and options before you decide.
Do I need a full bladder for the NT scan?
A moderately full bladder helps image quality. Drink 2–3 glasses of water about 30 minutes before your appointment. An uncomfortably full bladder is not necessary.
Why does FMF UK certification matter for the NT scan?
The Fetal Medicine Foundation (FMF), London, requires operators to complete training and quality review for standardised NT measurement. Dr. Mathew Thomas is FMF UK certified, so the examination follows the FMF measurement protocol used for first-trimester risk assessment.
Is the NT scan safe for my baby?
The NT scan uses non-ionizing ultrasound waves and no X-ray radiation. Diagnostic ultrasound has no known harmful effects when it is medically indicated and performed by a trained professional using the lowest appropriate exposure.
How much does this scan or test cost?
Fees vary by the exact scan or test advised. Call 9562390009 for the current fee; the team will confirm it before your appointment.
When will I receive the result?
Ultrasound findings are discussed with you and the written scan report is normally provided on the same day. Laboratory tests have separate processing times, which are explained before testing.
