The NT & NB Scan is the most important, time-sensitive screening in your first trimester. This non-invasive ultrasound (USG) precisely measures the 'Nuchal Translucency' (fluid at the back of the baby's neck) and confirms the presence of the 'Nasal Bone' (NB). These two markers, combined with our advanced Colour Doppler to check blood flow, are a powerful, early screening tool. This scan is the gold standard for assessing the risk of chromosomal conditions like Down syndrome and for the early detection of major heart defects. This is a routine, safe, and empowering check-up, providing you and your doctor with the first, critical insights into your baby's health.
