Yes, an NT scan can be wrong. Although it's a valuable screening tool for assessing the risk of chromosomal abnormalities, such as Down syndrome, it's not 100% accurate. The scan can produce false positives or negatives, meaning it might indicate a problem when there isn't one, or miss a problem that is present. It’s important to combine the results with other tests and your medical history for a comprehensive assessment.

FAQs & Answers

  1. What does an NT scan detect? An NT scan measures the nuchal translucency at the back of a baby's neck to assess the risk of chromosomal abnormalities like Down syndrome.
  2. How accurate is the NT scan? The NT scan is a valuable screening tool but not 100% accurate; it can produce false positives and false negatives, so results are combined with other assessments.
  3. What should I do if my NT scan results are abnormal? If your NT scan results indicate potential risk, your healthcare provider will likely recommend follow-up diagnostic tests and consider your full medical history.
