A nuchal translucency (NT) scan, is a valuable screening test offered between 11 and 14 weeks of pregnancy.
What is the NT Scan?
The NT scan involves an ultrasound to measure the clear space at the back of the baby’s neck between 11-14 weeks of gestation. This measurement, known as nuchal translucency, is essential for assessing the risk of certain chromosomal abnormalities of the baby, such as Down syndrome, Edwards syndrome, and Patau’s syndrome.
Chromosomes, are genetic material contained within body cells. Chromosomal abnormalities refer to irregularities in the structure or number of chromosomes.
The test, nationally, has a chromosomal abnormality detection accuracy rate of about 85% for Down’s syndrome. If it is positive, we might suggest a blood test to confirm diagnosis.
The measurement range for the nuchal translucency on scan is 1-3 mm. The likelihood of a genetic problem or a physical defect may be higher with the higher measurements.
The nasal bone of your unborn child is also visible on the nuchal translucency scan; if it is lacking, there is a higher chance of chromosomal abnormalities.
Compared to the NHS scans, this nuchal translucency scan is far more thorough and comprehensive
During this scan, we meticulously examine for the presence of your baby’s nasal bone, assess the development of your baby’s body, heart, stomach, bladder, hands, and feet. Additionally, we monitor unborn baby’s heartbeat to ensure their overall well-being.
What's included in an NT scan?
- Blood testing, risk assessment report, and dating
- Two 2D black and white pictures in a card frame that is mounted
- No cost 4D sneak peek (available for 12 to 22 weeks)
- If views are unclear, a transvaginal or internal scan could be performed.
- If precise measurements cannot be obtained, rescan for free.
- 20-minute scheduled time
- No GP referral is necessary.
- Professional and pleasant group
Why is it Done?
When is the test performed?
The scan is best done between 11 to 14 weeks or when the baby is measuring 45mm to 84mm.
While all babies have some fluid behind their neck, most babies diagnosed with Down syndrome have more than average.
It is always possible to become pregnant with a child who has Down syndrome, regardless of your age. If you become pregnant beyond the age of 35, your chances of having down’s syndrome increases.
Following a risk assessment based on your nuchal translucency ultrasound results, we can assist you in making informed decisions about whether to you need further investigation to confirm the diagnosis and you will be referred to a specialist centre to discuss about either for a non-invasive prenatal testing, or amniocentesis/chorionic villus sampling which are invasive tests that carries small risk of miscarriage.
Amniocentesis:
Involves the removing a small amount of amniotic fluid that surrounds your baby in the uterus.
It is normally done between weeks 15 and 20 of pregnancy.
It provides information about chromosomal abnormalities, genetic disorders, and neural tube defects.
Chorionic Villus Sampling (CVS):
Involves obtaining a small tissue sample from the placenta (chorionic villi).
This is usually performed between weeks 10 and 14 of pregnancy.
It assesses chromosomal abnormalities and certain genetic conditions in your unborn child.
Our ultrasound scans for nuchal translucency have an accuracy rate of 90–95%!
Preparing for your NT Scan:
Please attend with a comfortably full bladder.
Wear loose, two-piece clothing for easy access to your abdomen.
Results:
We send your scan report to your Specialist to discuss the results with you, combining the NT measurement with other factors. Remember, a higher NT measurement does not provide a diagnosis but indicates a need for further assessment.
Questions and Concerns:
Feel free to ask questions during the scan or discuss any concerns with us. We are here to support you every step of the way.

In Case You Still Have Questions
Do I need a GP/health care provider referral?
What is the referral process like?
We recommend that every one of our clients let their doctor or other healthcare provider know that they plan to get scanned by us. When you first arrive to Ultrasound Digital, you will be asked to fill out a registration form with information about your physician or healthcare provider.
Can I eat and drink before my scan?
Is it necessary to do an internal scan every time?
What do I need to wear for the scan?
What do I need to bring anything to my ultrasound scan?
Please bring along your hospital notes (if you have been given them) and reports to assist out Sonographers if a referral is required.
Will you advise me of any abnormalities?
Note that none of your NHS scans are replaced by our scans. Should a medical referral be necessary during your visit, we will address this with you and give you a comprehensive report to give to your physician.
Do I still need to visit the NHS if I had a scan with you?
Yes, our services are a complementary service, which works alongside the NHS.
Can I make a claim for my scans using my medical insurance?
After you pay Ultrasound Digital directly for your scan, we will send you an invoice. This is a private matter between you and your insurance provider, but it can be utilized to file a claim. Please verify this before your scan to avoid disappointment.
How many guests/children can come with me?
