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.
A nuchal translucency scan is combined with the mother’s age and results of a blood test showing the mother’s pregnancy hormone levels to provide a ‘combined risk’.
As with all tests in pregnancy, combined screening for Down’s syndrome is optional. This means that the screening will only identify a baby as being at a ‘high’ or ‘low risk’ of being affected by Down’s syndrome.
If you wish, you may also learn the baby’s sex during this ultrasound.
Ultrasound Scans can be separated between obstetric and non-obstetric.
Obstetric scans are performed mostly by sonographers or Obstetricians within the Antenatal Clinic on B-level.
It is a safer form of imaging compared to those that use ionizing radiation, such as X-ray and CT.
Non-obstetric scans are performed by Sonographers and Radiology Consultants within the Out patient Scanning Department on C Level and within the In Patient Radiology Day Case Unit (RDCU) also on C Level.
