12 Week Nuchal Scan with NIPT Harmony Test
A nuchal scan, or nuchal translucency (NT) scan, is often used as a screening test mainly for Down’s syndrome, as well as Edward’s and Patau’s syndromes and a number of major foetal abnormalities. The risk of Down’s syndrome and certain other abnormalities increases with the mother’s age.
Our medical team holds the licence from Fetal Medicine Foundation, authority on NT Screening, for 12 week Nuchal scan.
What is nuchal translucency (NT)?
Nuchal translucency is a collection of fluid under the skin at the back of your baby’s neck. It is measured using ultrasound in order to evaluate risk of a Down’s syndrome. All babies have some fluid at the back of their neck, but those with Down’s syndrome will have an increased amount.
The combination of NT scan and maternal serum free β-hCG and PAPP-A improves the detection to 90%. There is now evidence that the detection rate can increase to about 95% and the false positive rate can be reduced to 3% by also examining the nasal bone, ductus venosus flow and tricuspid flow.
When and how is NT scan performed?
- Between 11 – 13 weeks+6 days of pregnancy
- or when your baby measures between 45mm (1.8in) and 84mm (3.3in)
- it is performed externally with the ultrasound probe gently gliding over the abdomen, although in some cases it may be required to have a transvaginal scan. Both are painless and safe for you and your pregnancy
- our NT scan includes a blood test, processed by the Fetal Medicine Centre’s own laboratory, providing 97% accuracy in results
What will the scan examine?
- Amount of fluid at the back of the baby’s neck
- Presence or absence of baby’s nose bone
- Full anatomy and development check for any abnormalities
- Mother’s blood sample determines the level of 2 hormones- free beta-hCG and the protein PAPP-A. Babies with Down’s syndrome tend to have high levels of hCG and low levels of PAPP-A.
