About this test
The NT scan measures the fluid at the back of the baby's neck (nuchal translucency) and checks the nasal bone, heartbeat and early structure of the baby. Combined with the mother's age and a blood test (double marker), it estimates the chance of conditions such as Down syndrome. It is a screening test: it gives a risk, not a diagnosis.
When is it advised?
- Recommended for every pregnancy between 11 weeks and 13 weeks 6 days
- Screening for chromosomal conditions such as Down syndrome
- Early check of the baby's structure
- Screening for pre-eclampsia risk, when advised
How to prepare
- Book within the window: 11 weeks to 13 weeks 6 days. The measurement cannot be done reliably outside it.
- Come with a partly full bladder (2–3 glasses of water an hour before).
On the day
- A female staff member (chaperone) is always present during the scan.
- Bring a photo ID (required by law for every pregnancy scan), your doctor's prescription and your previous scan reports.
- You will fill and sign the PC-PNDT Form F, as required for every pregnancy scan in India.
- The report is prepared by the radiologist, handed to you and also shared on WhatsApp.
Frequently asked questions
What if the NT measurement is high?
A higher measurement increases the estimated risk but does not mean the baby has a condition. Your doctor may advise further tests such as NIPT or an amniocentesis.
Do I still need the anomaly scan?
Yes. The Level II anomaly scan at 18–22 weeks checks the baby's organs in much more detail.
