Nuchal Translucency (NT)

Nuchal Translucency (NT) measures the fluid under the skin at the back of baby's neck between 11-13 plus weeks with limited structural examinations to evaluate:

  • Pregnancy dating by measuring the Crown Rump Length.
  • Diagnose multiple pregnancies.
  • A number of common major structural anomalies can be seen at this stage
  • Risk assessment of your baby being affected by most common chromosomal anomalies like Down’s Syndrome.
  • Training, Experience of physician or sonographer and obviously better technological support via better imaging machines improve the accuracy of this test but NT risk assessment alone can miss 500/10,000 affected pregnancies.
  • A blood test will be taken as well which will measure levels of two pregnancy-specific hormones in your blood (beta hCG, plasma protein-A). to asses risks of (T21, T13 & T18).
  • A better, more accurate but more expensive test is developed called NIPT which insurances unfortunately only cover with many exclusions.
  • At our center, almost all patients perform NIPT testing missing 1/10,000 affected pregnancies and performed at 9 weeks & 2 days instead of 11-13 weeks.
  • With follow up structural NT scan.
