Your pregnancy – What to expect

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.
