NT Scan
Nuchal Translucency Scan is carried out between 11 to 14 weeks of pregnancy.
NT Scan was introduced in the 90’s which allows healthcare professionals to check the baby’s risk of having any chromosomal abnormalities. If the NT Scan report turns out abnormal, NIPT (non-invasive prenatal test ) can be carried out soon after the results. NIPT is one of the most reliable prenatal screening that can detect the possibility of the fetus having chromosomal abnormality.
NT scan is a vital step in ensuring your baby’s health right from the first trimester to make informed decisions.

What is NT scan in pregnancy?
NT Scan is a crucial non-invasive ultrasound screening carried out between 11 to 14 weeks of pregnancy to analyze the risk of any chromosomal abnormalities in the fetus such as Down syndrome and Edward's syndrome.
Why is NT Scan important?
NT Scan is one of the most important prenatal screening that is done to determine the chances of the fetus having any chromosomal abnormalities and birth defects.
What happens if an NT scan is normal?
NT scan normal range must be less than 3.5 mm. If you get a normal NT Scan report, it means that your baby has low risks of having chromosomal abnormalities.
What happens if an NT scan is abnormal?
If the NT Scan report is abnormal, that is if the nuchal thickness is over 3.5 mm, then your gynecologist will suggest further interventions such as amniocentesis, and CVS to make informed decisions.
Is NT scan 100% accurate?
No. NT scan is not 100% in detecting the baby’s risk of having chromosomal abnormalities. However, NT scan is usually combined with a test called double marker test. Both of these tests together are around 85% accurate.
If your NT scan report is abnormal, your doctor would recommend further screening including NIPT, Amniocentesis and CVS.
What do we check during NT scan?
During the ultrasound scan, we measure the thickness of the nuchal fold. Nuchal fold is the normal skin fold that is present in the back of the fetus’s neck.
If the nuchal thickness is less than 3.5mm, it means that the baby has low risks of chromosomal abnormalities.
But if the thickness is more than 3.5mm, it means the results are abnormal and you would require further intervention.
If the NT scan is normal, will the double marker test also be normal?
Not necessarily. Sometimes, the NT scan report can be normal but the double marker test can be positive. In such cases, your doctor might prescribe for further intervention such as CVS and amniocentesis.
