There is a 17-day window in your pregnancy where one scan can tell you more about your baby’s health than any other test available.
Miss it — and that information is gone forever.
The NT/NB scan between 11 weeks 3 days and 13 weeks 6 days measures two completely separate things: the fluid at the back of your baby’s neck (Nuchal Translucency) and the presence of the nasal bone. Together with a blood test, this combined screening detects up to 87% of trisomy 21 cases in the first trimester.
30,000 children are born with Down syndrome in India every year. Most families were never screened.
This is not a routine check. This is a specialist assessment — and the accuracy of the measurement depends entirely on the experience of the radiologist performing it.
Swipe through to understand exactly what is measured, what the numbers mean, and why booking before week 14 is non-negotiable. 👉
