Nuchal translucency (NT) screening is a non-invasive screening test used to determine the risk of Down syndrome. It can be performed early in pregnancy, from 11 weeks to 13 weeks and 6 days, and is available to women of all ages. ![women-at-ultrasound](https://edge.sitecorecloud.io/sutterhealt962c-sutterhealt8fce-production57cc-4860/media/Project/SutterHealth/SutterHealth/Images/people/family/women-at-ultrasound.jpg) ### How is NT screening performed? NT screening is a high-resolution ultrasound examination of the baby’s nuchal area (a fold of skin at the back of the neck). The results are combined with maternal age to determine the risk for Down syndrome. ### Will the test detect all cases of Down syndrome? The detection rate for Down syndrome is about 80% for NT screening. Depending on the results, you would then have the option of undergoing CVS or amniocentesis for a more definitive diagnosis. ### Will this test identify spina bifida? No. The ultrasound is performed too early to reliably detect this disorder. Talk to your provider about nuchal translucency screening and other recommended prenatal testing.
