NT / NB SCAN
The NT/NB Scan is a specialized prenatal ultrasound performed between 11 to 14 weeks of pregnancy. It is an early screening test used to check the baby’s development and detect the risk of chromosomal abnormalities, such as Down Syndrome (Trisomy 21) and other genetic conditions.
Measures the fluid-filled space at the back of the baby’s neck.
A thicker NT measurement may indicate a higher risk of chromosomal issues.
