The NT scan, or Nuchal Translucency scan, is one of the earliest and most important steps in your pregnancy care journey. Usually done between 11 to 14 weeks of pregnancy, this safe and non-invasive ultrasound gives valuable insights into your baby’s development and overall well-being.During this scan, the doctor gently measures a clear space called "nuchal translucency" at the back of your baby’s neck. This small fluid-filled area can give clues about the risk of certain chromosomal conditions, such as Down syndrome, Edwards syndrome, or Patau syndrome. A slightly larger space may be linked to a higher chance of these conditions, which is why the NT scan is often combined with a blood test for more accurate results.But the NT scan is not just about screening. It also confirms your baby’s heartbeat, checks basic development, and helps estimate how far along you are by measuring the baby’s size.This test is especially useful because it gives you and your healthcare provider early information to make well-informed decisions about any next steps. For most parents, the NT scan brings comfort and confidence, especially when everything appears normal and on track.There are no risks to you or your baby. The scan is done externally on your belly using ultrasound, and it takes around 15 to 30 minutes. It's painless and provides quick, valuable results that set the tone for healthy pregnancy care.
