The necessity of doing NT test is that the nuchal translucency scanner is a way to assess whether the fetus is likely to have Down syndrome, which is a screening method. NT tests are different from confirmatory tests such as chorionic villus aspiration biopsy or amniocentesis. They can provide a clear diagnosis, but NT tests can only indicate risks.

The accuracy of the nuchal translucency examination is determined by many factors, including the level of the ultrasound doctor and the accuracy of the scanner used, so the examination results cannot be guaranteed to be 100% accurate.
