Also known as the 12–13 week scan, Down Syndrome scan, safety scan, or first trimester screening, a nuchal translucency (NT) scan is a crucial early pregnancy ultrasound that helps assess the likelihood of certain chromosomal abnormalities, such as Down Syndrome.
During this nuchal translucency test, we measure the fluid-filled space at the back of your baby’s neck. Your GP or obstetrician will also arrange for a first trimester blood test, which is sent to a genetic centre. The results from your blood test and the NT ultrasound are combined to evaluate the probability of Down Syndrome, and a detailed report is then sent to your doctor.
In addition to this screening, we conduct an early anatomy check to ensure your baby’s features and organs are developing as expected. Plus, if you schedule your NT scan closer to 14 weeks, we can often determine your baby’s gender with up to 99% accuracy—adding an exciting extra benefit to this important assessment.

What’s included:
The nuchal translucency scan is a safe and non-invasive prenatal test that can be used to screen for certain birth defects, including Down syndrome. The test is performed during the first trimester of pregnancy and involves using ultrasound to measure the thickness of the nuchal fold, which is the skin at the back of the baby’s neck. A high nuchal translucency measurement may be an indication of Down syndrome or another chromosomal disorder.
The nuchal translucency scan is usually performed between 12 and 14 weeks of pregnancy. The test is often combined with a blood test, which can further increase its accuracy.
The nuchal translucency scan is usually performed between 12 and 14 weeks of pregnancy.
The nuchal translucency scan has several benefits. It can help to determine the risk of the fetus having certain chromosomal abnormalities, such as Down syndrome. It can also help to assess the risk of other conditions, such as heart defects
You should drink some water before the scan so that your bladder is full. This helps to improve the quality of the images.
During your nuchal translucency scan, a sonographer will use a transducer to emit high-frequency sound waves through your abdomen and measure your baby from crown to rump. Your sonographer will check if the fetal age is accurate. After that, he or she will measure the thickness of the nuchal fold on the screen. Together with your age and your baby’s gestational age, these measurements will be used to calculate the probability of a chromosomal abnormality. Although this number cannot give you a definitive diagnosis, it can help you decide whether or not you should undergo further testing.
