Why Have a Nuchal Translucency scan?
All women, regardless of their age have a small risk of delivering a baby with a chromosomal abnormality such as Down syndrome. Nuchal translucency assessments can assess the individual risk for each expectant mother (i.e. 1 in 100 chance of a chromosomal abnormality). This information can determine whether or not further investigation is required. Nuchal translucencies have shown to identify around 80% of all Downs syndrome cases. The examination is designed to give parents the information in which to make their own decisions on what to do should the risk of abnormalities be high.
