Nuchal Translucency
What is a Nuchal Translucency examination?
All women, whatever their age, have a small risk of delivering a baby with
physical and/or intellectual disability. Sometimes the disability is due to a
chromosomal abnormality such as Down syndrome (also known as Trisomy 21).
The Nuchal Translucency examination, which involves a combination of a special
ultrasound and a blood test, is offered to pregnant women to assess major
chromosomal congenital anomalies. The test suggests which pregnancies are at a
higher risk of abnormality and may need further investigation. A normal result
does not guarantee a normal baby but does imply that an abnormality is unlikely.
An abnormal result does not mean the baby is abnormal but suggests the baby
should be further investigated.
Preparation
The examination also confirms the pregnancy dates, development and number of
foetuses or embryos in the uterus.
You will need to make an appointment for this examination. The
blood test (which should be arranged with a pathology clinic) is recommended
during the 10th week of pregnancy. The Ultrasound scan (with SKG Radiology) is
then performed ideally at 12 weeks (11 ? 13 weeks) of pregnancy, but no later
than 13 weeks 6 days of pregnancy. You will be asked to drink fluids to fill
your bladder prior to the ultrasound.
