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. Your health care provider will schedule your NT ultrasound at a hospital or a clinic with a certified NT sonographer or physician.

Nuchal translucency is the name for the normal fluid space behind the neck of a foetus unborn baby that can be seen on ultrasound scans. A nuchal translucency scan also called first trimester of pregnancy screening is carried out during weeks 11—13 of a pregnancy. The scan uses ultrasound to screen for Down syndrome, or other chromosomal or inherited conditions in the foetus. Other non-chromosomal conditions, such as neural tube defects, abdominal wall defects, limb abnormalities and some congenital heart disease, can also be detected at this stage of the pregnancy.
Screening can determine the likelihood of risk of an abnormality, but does not diagnose the condition. If screening does identify a possible risk, it does not necessarily mean there is an abnormality present, but does mean that further testing is necessary. Women who return a high-risk result from the screening will be offered formal genetic testing using other procedures, such as amniocentesis or chorion villus sampling CVS. All women are offered a nuchal translucency test regardless of their age, and 19 out of 20 women have a normal screening result.
Any patient might be referred for a nuchal translucency test regardless of their age. Your referring doctor GP or obstetrician will be able to tell you whether you are eligible for a Medicare rebate for the scan.
