The nuchal translucency NT refers to the pocket of fluid at the back of the fetal neck. The measurement of the nuchal translucency is part of the combined screening test for trisomy 21 and trisomy 18, called enhanced First Trimester Screen eFTS. An increased NT measurement increases the chance for other chromosome differences, additional genetic conditions, and can also be helpful to predict structural differences that might be more obvious later in pregnancy such as a heart defect.
At the time of the NT ultrasound, the sonographer or physician who does the scan can also accurately predict your due date, determine how many babies you are carrying and examine the early basic structural development of the fetus. Examples of circumstances when this may be applicable are: declining to have prenatal screening for trisomy 21 and trisomy 18, Non-invasive Prenatal Testing NIPT has already been initiated, or the pregnant individual is carrying more than two babies triplets, quadruplets etc.
