Nuchal Translucency (NT Scan)

Nuchal Translucency (NT Scan) is a prenatal ultrasound scan that enables medical professionals to assess the risk of congenital chromosomal disabilities in unborn babies. It is a non-invasive and safe procedure that uses a transducer to measure fluid thickness at the back of the baby's neck. The results of this scan can help expectant parents make informed decisions about their pregnancy and provide peace of mind. Furthermore, NT scanning can detect potential Down syndrome cases early. This informative website provides detailed information on NT Scan and other related topics.

What Are the Different Types of NT Scans?

There are three main types of nuchal translucency (NT) scans: the combined test, the integrated test, and the quadruple test. The Combined Test is a screening test that involves a blood test and an ultrasound to determine the chance of a baby having Down syndrome or another chromosomal abnormality. The Integrated Test combines the results of the Combined Test with maternal age and other factors to calculate risk levels. Finally, the Quadruple Test includes three different blood tests that measure levels of hormones in a pregnant woman's body to help identify the risk for chromosomal abnormalities.

Who Qualifies for the NT Scan?

Anyone pregnant between 11 and 14 weeks of gestation may qualify for an NT scan. The scan is safe and non-invasive to complete without posing any risk to the mother or unborn baby. An NT scan is most often offered to pregnant women over 35, as they have a higher risk of having a baby with chromosomal abnormalities. It is also recommended for anyone who has had an abnormal result from a previous screening test or has a family history of chromosomal abnormalities.

When would a doctor suggest undergoing nuchal translucency?

Doctors recommend an NT scan in the first trimester of pregnancy to help assess the risk of chromosomal abnormalities like Down syndrome. It is usually performed between 11 and 13 weeks of gestation and involves a detailed ultrasound scan to measure the clear space at the back of a baby's neck. In certain cases, it may be advised that women have a double test that combines the NT scan results with a blood test. The combined result helps give an accurate indication of whether the baby is likely to have any chromosomal defects.

How Should You Prepare for the NT Scan?

Preparing for a nuchal translucency (NT) scan is important and involves ensuring that you have a full bladder before the appointment. This can be achieved by drinking plenty of water or other non-alcoholic drinks an hour before the scan. You should also wear comfortable clothing with easy access to your abdomen, as ultrasound gel may need to be applied. In addition, it is best to avoid lotions and oils on the day of the scan, as these can interfere with the procedure. Finally, it is advisable to bring someone along for support who can provide information relevant to the scan if needed.


A Nuchal Translucency (NT) Scan is a safe and widely used procedure that helps detect possible risks of congenital disabilities in an unborn fetus. Through this procedure, medical experts can assess the risk of chromosomal abnormalities that may be present in the fetus. The NT Scan can provide couples with valuable information and the opportunity to make decisions that are best for their family. It is an important part of prenatal care and offers peace of mind during pregnancy. In conclusion, the nuchal translucency (NT) scan is an invaluable tool for pregnant women and their families, helping to ensure a healthier future for their children.
