NT Scan Price List Delhi 2026

"NT Scan only" is the ultrasound measurement alone. "NT + Double Marker" is the recommended combined first-trimester screening — significantly more accurate than NT alone. The double marker blood test must be done in the same laboratory reference period as the NT scan for the combined risk calculation to be valid.

The Most Important Thing About Your NT Scan — Read Before Booking

This section does not appear on any other NT scan page in Delhi. It directly affects the quality of your result.

The NT measurement is accurate to fractions of a millimetre. The sonographer's training determines whether your result is clinically reliable.

NT screening detection rates vary from 29% to 100% across published studies — the large variation is believed to be due to significant differences in ultrasound training and NT image quality. Sonographers must acquire a measurement accurate to a fraction of a millimetre, which is used like a laboratory analyte to assign a specific patient risk for aneuploidy. Testbook

The Fetal Medicine Foundation (FMF) — the international body that sets the NT scan protocol — certifies sonographers who have undergone specific training and passed a standardised image quality assessment. FMF certification has a statistically significant positive impact on NT measurement quality standards. CRPF

What this means in Delhi:

In India, sonologists often lack access to the Fetal Medicine Foundation Down syndrome risk calculation software or cannot offer the combined test for aneuploidy screening because of resource constraints — instead relying on fixed NT cut-offs rather than individualised risk calculation. Wikipedia

The difference matters practically: an FMF-certified sonographer uses the FMF software to calculate your individualised Down syndrome risk based on your age, NT measurement, nasal bone, and blood test values together. A non-certified sonographer may simply note whether your NT is above or below a fixed cut-off of 3.0mm — which is a less sensitive and less specific approach.

What to ask when booking: "Is your sonographer FMF-certified for NT scan?" or "Do you use FMF risk calculation software for the combined first-trimester screen?" If the centre cannot answer this question, consider choosing a different centre for your NT scan.

EVE Healthcare partner centres offering NT scans confirm FMF certification status at the time of booking.

What Is the NT Scan — In Plain Language

The NT scan (Nuchal Translucency scan) is an ultrasound performed between 11 weeks and 13 weeks 6 days of pregnancy. It measures a specific structure: the fluid-filled space at the back of the fetal neck. When this space is larger than expected, it raises the statistical risk of chromosomal conditions — primarily Down syndrome (Trisomy 21), Edwards syndrome (Trisomy 18), and Patau syndrome (Trisomy 13).

What the scan also checks:

• Nasal bone — presence or absence
• Fetal heartbeat and rate
• Crown-rump length (CRL) — confirms gestational age
• Basic fetal anatomy — head, limbs, abdominal wall
• Fetal position and early placental location

What the NT scan is not:

• Not a definitive diagnosis — it is a risk calculation, not a confirmation
• Not the anomaly scan — structural anatomy is not fully assessed until the Level 2 TIFFA scan at 18–22 weeks
• Not a guarantee — a normal NT result significantly reduces risk but does not eliminate it

NT Scan Alone vs Combined First-Trimester Screen — Which Do You Need?

This is the most important clinical decision at the NT scan stage.

NT scan alone: When performed between 11 and 13 weeks of gestation, the NT scan alone can detect approximately 75–80% of Down syndrome cases in fetuses of mothers aged 35 and older. District South West, Delhi Government

Combined first-trimester screen (NT + Double Marker blood test): The combination of NT and maternal serum free β-hCG and PAPP-A improves the detection rate to 90%. Demo

Combined screen + additional markers (nasal bone, ductus venosus, tricuspid flow): There is evidence that the detection rate can increase to about 95% and the false positive rate can be reduced to 3% by also examining the nasal bone, ductus venosus flow and tricuspid flow — assessed by FMF-certified sonographers. Demo

The clinical recommendation for most patients: Always book the combined NT + Double Marker package — not NT alone. The blood test adds ₹1,000–₹2,000 to the cost and increases detection from 80% to 90%. The blood test must be done within the same reference window as the NT scan (ideally same day or within a few days). EVE Healthcare partner centres offering combined packages coordinate the blood draw and the ultrasound in a single visit.

Understanding Your NT Measurement

The crucial context: NT measurement alone is not the result. The result is your combined risk score — a number like "1 in 450" or "1 in 50" — generated by the FMF software using your age, NT measurement, nasal bone status, PAPP-A, and free β-hCG values together. A woman aged 38 with an NT of 2.8mm may have a higher combined risk than a woman aged 25 with an NT of 3.1mm. Your gynaecologist interprets the combined score — not the NT measurement in isolation.

What Does a High NT Result Mean?

This is what parents search for at midnight after receiving their NT report. It deserves an honest, specific answer.

A high NT result means your baby has a statistically higher probability of certain chromosomal conditions. It does not mean your baby has any of those conditions.

The majority of fetuses with elevated NT measurements are born healthy. NT elevation is associated with:

• Down syndrome (Trisomy 21) — most common association
• Edwards syndrome (Trisomy 18)
• Patau syndrome (Trisomy 13)
• Turner syndrome (45X)
• Congenital heart defects — even with normal chromosomes
• Other rare genetic syndromes

What happens after a high NT result:

Step 1 — Your gynaecologist reviews the combined risk score. A combined risk score above 1 in 250 is considered high risk. Between 1 in 250 and 1 in 1000 is intermediate risk. Below 1 in 1000 is low risk.

Step 2 — NIPT is offered as next step for high or intermediate risk. NIPT (Non-Invasive Prenatal Testing) is a maternal blood test that analyses fetal DNA fragments. Sensitivity above 99% for Down syndrome, Edwards, and Patau. No risk to the pregnancy. Results in 7–14 days. Cost in Delhi: ₹8,000–₹18,000.

Step 3 — For high NT (above 3.5mm) regardless of combined score: Referral to a Fetal Medicine Specialist (FMS) for detailed assessment and cardiac evaluation is recommended even if NIPT returns normal — because elevated NT is also associated with congenital heart defects that NIPT cannot detect.

Step 4 — Diagnostic testing if required: Amniocentesis or CVS for a definitive chromosomal result. Only recommended when confirmed high risk after NIPT or when NIPT is inconclusive.

The honest reassurance: Most couples who receive a "high risk" combined score and proceed to NIPT or amniocentesis receive normal results. The screening process exists precisely because it identifies a high-risk group so that the large majority of babies who are healthy can be identified with confidence, and the small minority who need additional support can be found early.

The NT Scan Window — The Booking Mistake That Cannot Be Undone

The NT scan can only be performed between 11 weeks 0 days and 13 weeks 6 days of pregnancy. Not one day earlier. Not one day later.

Before 11 weeks, the NT space is too small and indistinct to measure accurately. After 13 weeks 6 days, the fetus has grown and the NT space naturally closes — the measurement cannot be taken.

The most common NT scan booking error EVE patients make: Assuming they have more time than they do. A patient who books at 13 weeks on the calendar is often already past the window when they arrive — because gestational age is counted from the first day of the last menstrual period, not from conception, and small date discrepancies matter when the window is only 21 days wide.

How to protect your NT window:

• Book your NT scan appointment at week 11 or 12 — not week 13
• Bring your dating scan report (viability scan) — the sonographer confirms gestational age by crown-rump length (CRL) measurement. If your CRL puts you past 13 weeks 6 days, the NT measurement cannot be done
• If you are uncertain of your dates, book earlier rather than later
• If you have a dating scan that shows you are at 10 weeks 4 days today, book the NT scan for 7–10 days from now — not 3 weeks from now

If you miss the NT window: The NT scan cannot be performed. First-trimester combined screening is no longer possible. Your gynaecologist will recommend second-trimester screening — the quadruple marker blood test at 15–20 weeks — which has a lower detection rate than the combined first-trimester screen. This is clinically manageable but avoidable.

CGHS Rates for NT Scan in Delhi

Source: CGHS Rate Schedule effective October 2025, Ministry of Health & Family Welfare, Government of India.

Bring your CGHS Smart Card and a valid referral letter from your CGHS CMO or empanelled gynaecologist. Confirm CGHS empanelment before visiting. Note that CGHS does not cover NIPT — this is an elective screening test not included in the rate schedule.

Preparation for Your NT Scan

Full bladder required for most NT scans: Drink 4–6 glasses of water 1 hour before and do not urinate. A full bladder lifts the uterus and improves visibility for a transabdominal scan.

If transvaginal is needed (usually in early weeks 11–12): Empty your bladder. The sonographer will inform you at registration if transvaginal is planned.

Do not fast: Unlike some scans, the NT scan does not require fasting. Eat normally. An active baby after a light meal can actually help the sonographer achieve the correct neutral-position image for measurement.

Bring to your NT scan appointment:

• Your viability / dating scan report (if done)
• Aadhaar card — required under PC-PNDT Act
• CGHS card and referral letter if applicable
• Previous pregnancy scan reports if this is not your first pregnancy

The preparation note every pregnant woman needs: The NT measurement requires the fetus to be in a specific neutral position — head neither too flexed nor too extended. If the fetus is not cooperating, the sonographer may ask you to walk around, have a cold drink, or return in 20–30 minutes. This is not unusual and is not a sign that anything is wrong with the baby. Budget 60–90 minutes for your NT scan appointment.

Clinical Note

From the reviewing fetal medicine specialist: The NT scan is the first window into fetal wellbeing — and also the most technically demanding scan of the pregnancy. The measurement must be taken in a specific sagittal plane, with the fetus in neutral position, at a specific magnification, to a precision of 0.1mm. A difference of 0.3mm in the NT measurement can change the Down syndrome risk calculation significantly. In my practice, I always advise patients to book their NT scan at an FMF-certified centre — not because uncertified sonographers are poor practitioners, but because the NT measurement protocol is extremely specific and FMF certification is the only external quality standard that confirms a sonographer has been trained and audited to that protocol. For the combined first-trimester screen to be clinically valid, the NT measurement must be of sufficient quality that the FMF software can use it as an analyte alongside the blood test values. A measurement taken outside the FMF protocol may not meet this standard — which means the combined risk score may not be clinically reliable regardless of what the printed report says.
