NT/NB Scan

NT/NB Scan (1st Trimester Ultrasound) – Kathmandu

An NT/NB scan in Kathmandu (Nuchal Translucency and Nasal Bone ultrasound) is a specialized first-trimester test performed between 11 and 13 weeks of pregnancy. It measures the fluid at the back of the baby’s neck and evaluates the nasal bone. Additionally, this scan helps screen for chromosomal conditions such as Down syndrome.

This non-invasive ultrasound allows doctors to assess early pregnancy risks. Importantly, early detection supports better medical planning and follow-up care. At Lomash Health Care Center (Thapathali), our experienced team uses modern ultrasound technology to deliver accurate results on the same day.

When and Why Get an NT/NB Scan
