Combined Nuchal Screening



The Combined Nuchal Translucency Scan, also known as a Nuchal or NT Scan, is a combined screening test to detect the probability of your baby having a chromosonal disorder such as Downs Syndrome.

The test combines the results of an ultrasound scan, a blood test and the age of the mother. It can only be performed between the gestational stages of 11+3 – 13+6 weeks (11 weeks 3 days to 13 weeks 6 days).

The results of the Combined Nuchal Scan come back from the laboratory within 24 to 48 hours and will be relayed to you by email or telephone call, as soon as we receive them.

If we have time during your appointment, we will also offer to show you the baby in 4D free of charge.

If you know you are carrying twins or a multiple pregnancy, please let us know when you book. We need to allow more time for multiple pregnancies and charge an extra £60 for each additional baby.

This is not a diagnostic test. The results of a Combined Nuchal Scan are approximately 96% accurate and give the probability of your baby having a chromosomal disorder. The NHS currently considers results of up to 1 in 150 as low risk and anything above this, i.e. 1 in 135 as increased, or high risk.

If you receive a high risk result, The NHS will offer you either an Amniocentesis or a CVS, depending on the gestation of your pregnancy, which are invasive tests and carry a risk of up to 1% of causing a miscarriage. Visit the NHS website to find out more.

We offer NIPT (Non Invasive Prenatal Tests), which analyse the baby’s DNA from a sample of the mothers blood and give a greater than 99% accurate result, with no risk of miscarriage. Find out more.
