For more information of prenatal diagnostic testing, please go to: The nuchal translucency is the fluid found at the back of your baby’s head and neck, just beneath the skin.
The thickness of this fluid can be precisely measured and this is called the nuchal translucency (or NT) measurement.
This means that combined first trimester screening simply tells us if your risk is low or high.
At the same time, there are couples who want to wait and choose not to find out the baby’s gender until the moment of birth.
They want the discovery of whether the baby is a boy or a girl to be a surprise.
Normally the amount of fluid is small, producing a thin NT measurement.
We know that the amount of fluid can increase in the presence of certain conditions, producing a thicker NT measurement.
Conditions associated with an increased NT measurement include some chromosome abnormalities (for example, trisomy 13, 18 and 21) and some structural problems (for example, heart abnormalities).
