How NT Scan and Double Marker Test Work Together

The NT (Nuchal Translucency) Scan and Double Marker Test are complementary first-trimester screening tests performed between 11 and 14 weeks of pregnancy. The NT Scan measures the fluid at the back of the baby's neck, while the Double Marker Test analyses specific pregnancy-related substances in the mother's blood. When the results are combined, they provide a more accurate assessment of the baby's risk of chromosomal conditions such as Down syndrome, Edwards syndrome, and Patau syndrome. Early screening helps doctors recommend appropriate follow-up tests if needed. Aarna Diagnostic offers advanced NT Scans and reliable laboratory testing to support a healthy and informed pregnancy journey.
