Is nuchal transparency 100% sure as an indicator?
Nuchal transparency is a tool used to screen for trisomy 21. It is 70% accurate when used alone. It is important for the people measuring nuchal transparency to be experienced and specially trained, otherwise the accuracy level will be even lower. When combined with 1st and/or 2nd trimester blood markers, the test’s accuracy improves. You should discuss the availability of nuchal transparency screening in your area with your doctor.
