What is the Nuchal Translucency scan?
The Nuchal Translucency (NT) is a skin fold on the back the neck measured approximately between 12.5 and 13.5 weeks gestation.
Other fetal structures are also assessed. The NT thickness is measured and this gives the risk or estimate of the baby having
Down’s Syndrome and other conditions. Different data (for example the mothers age and weight) is then entered into a state of
the art computer software program attached to the FMF. This then gives the risks or odds of baby having Down’s Syndrome and
other conditions. These results are provided to your referring doctor within the next few days. This is not a definitive assessment
and is used to assess risk only. Different factors can affect the NT. The ultrasound may be combined with a blood test to give a
more accurate assessment. We do not carry out the blood test at our clinic this will need to be arranged through your GP and this
will calculate the combined risk factor. Please call the clinic if you have questions regarding this procedure.
You will be given several photos of baby, often of the face profile, at the end of the scan.
