Nuchal Translucency Scan

Nuchal Translucency Measurement & Screening Test

When you come along for your 12-week screening test or ultrasound, you will be offered to take part in a nuchal translucency test. This ultrasound scan is performed to determine the probability of chromosomal abnormalities such as Down’s Syndrome, Edwards Syndrome and Patau’s Syndrom; it will also help diagnose any structural conditions to the baby’s neck. Prenatal screening is essential as the tests carry the potential to highlight something abnormal.

When carrying out a nuchal translucency scan, we perform an ultrasound that will confirm your baby’s heartbeat is vital and how many babies you should be expecting. We will also carry out diagnostic testing. By this, we mean, check fluid at the back of the neck, the nasal bone is present, your baby’s heart rate, body, heart, stomach, bladder, hands and feet. Baby growth is essential, and we want to confirm everything is moving in the right direction.

The screening test and trimester screening programme have been put in place to look at all aspects of the pregnancy, including the pregnant women, placenta, amniotic fluid and umbilical cord. During the nuchal translucency scan, our team will be on hand to answer any questions or queries you might have; if there are any issues.

What does a NT scan include?

What Will The Nuchal Translucency Scan Detect?

When we carry out the Nuchal Translucency test, we are searching for chromosomal abnormalities through the process of an ultrasound scan; this diagnostic test is to determine whether or not your baby is at risk of developing Down’s Syndrome, Edward’s Syndrome and Patau’s Syndrome. When searching for a chromosomal abnormality, the test has an accuracy rate of above 85% at detecting down’s syndrome. If it is detected, we may recommend a blood test to investigate further. The process is as follows for looking at chromosomal abnormalities;

  • Nuchal Translucency measurement is the measurement taken from the ultrasound scan, which detects the fluid present behind the baby’s neck. This measurement is tiny and is taken in millimetres. Fetal nuchal translucency is one of the prenatal diagnosis factors for Down’s Syndrome.
  • The nuchal translucency NT scan measures between 1-3mm. The larger measurement may increase the chance of chromosomal abnormality or a physical condition being present.
  • The nuchal Translucency scan also shows the presence or absence of your baby’s nasal bone; if it is absent, it will increase the risk of chromosomal abnormality.
  •  Fetal heart rate measurement and diagnostic testing measure the number of times your baby’s heart beats in a minute. The main reason for this part of the combined test is to check for signs of Edwards Syndrome and Patau’s Syndrome.
  • A much more extensive Nuchal translucency scan than the NHS, giving you a detailed fetal scan, combined screening of the following; head, brain, face, stomach, heart, abdominal wall, bladder, hands and feet. This determines the presence of any physical conditions which can be determined at this stage of pregnancy.

Our nuchal translucency ultrasounds have a 90-95%
accuracy rate!

We recommend our NT scan to all pregnant women who would like to assess their baby’s risk of Down’s Syndrome; although the scan cannot tell whether your baby will be affected, it can help you decide whether or not you should have further diagnostic tests. A Nuchal Translucency scan is essential to help monitor your baby’s well being.

Nuchal Translucency is the collection of fluid under the skin at the back of your baby’s neck. An NT Scan will measure this using ultrasound technology when your baby is between 11 and 14 weeks old or measures between 45mm and 84mm. All babies have some fluid, but most babies with Down’s Syndrome have an increased amount. Prenatal testing will help determine if your baby has any chromosomal abnormality issues.

No matter your age, there is always a chance you may have a baby with Down’s Syndrome. Suppose you conceive over the age of 35, the chance increases. A nuchal translucency ultrasound will let you know how high your risk may be and will help you decide if you should go on to have amniocentesis or chorionic villus sampling tests.

What is the purpose of an NT scan?

The purpose of an NT (nuchal translucency) scan is to assess if your baby may be affected by Down’s Syndrome. A risk assessment will be created after a measurement of the baby’s nuchal fold, crown-rump length and foetal heart rate is taken. The foetal gestation age and placental position will also be identified during a nuchal scan, and we can confirm whether it is a single/multiple pregnancies.

NT Scan FAQs

NT scans are an accredited screening process performed from 11 to 14+1 weeks of pregnancy. The fluid area behind the foetal neck is measured using ultrasound. The blood is measured for 2 naturally occurring hormones by the Fetal Medicine Centre’s laboratory. These blood results, combined with the ultrasound measurements determine the risk factor.
In accordance with NICE (National Institute for Health and Care Excellence) regulations, NT scans are initially the most accurate form of identifying Down’s Syndrome babies. There are no age restrictions to being screened. It is a personal choice and is available to everyone.
Ultrasound Plus NT Scans follow the standard NHS protocols and guidelines. The Nuchal Translucency measurements (NT), Crown Rump Length (CRL), Foetal Heart Rate (FHR) are measured. Your approximate weight and height will also be requested to help assist the sonographer. Further information is also requested during your nuchal translucency scan, such as whether you smoke during your pregnancy and if it is a natural/IVF pregnancy. These questions are asked to process the risk factor on the FMF software. No chromosomal markers will be examined.
At Ultrasound Plus, we assure 90 to 95% accuracy with the combined nuchal translucency ultrasound & blood screening (80% accuracy with only an ultrasound) – therefore, not all pregnancies with Down’s Syndrome may be detected. The NT screening and scan determines your risk of carrying a Down’s Syndrome baby or other similar types of chromosome abnormalities.

If you are classed as a high-risk patient, you can then receive further follow-up tests, like CVS (Chorionic Villous Sampling) or Amniocentesis. These follow-up tests will help determine the certainty of your pregnancy being affected by Down’s but are only recommended if necessary as they carry a small chance of miscarriage.
If your results indicate an increased risk of carrying a Down’s baby, this means your NT scan results, combined with your blood results and your age, gave you an approximate 1 in 150 or higher chance that your baby has Down’s Syndrome.

Ultrasound Plus will advise you to discuss your findings with your GP &/or midwife. If you wish, Ultrasound Plus can also provide you with details on where you can receive further follow up tests.
In such instances, we will charge you for a dating scan and rebook for a NT scan at a later date.
If the baby is not in a good position during your nuchal translucency ultrasound, we will request you move around and our sonographers will attempt to re-scan you a maximum of 3 times. If this is unsuccessful, we will invite you back for one rescan at no extra cost.
At ultrasound plus, we are pleased to offer patients one rescan at no extra cost. We value the importance of the bonding experience for our patients and their families and due to circumstances beyond anyone’s control on the day of the scan, images may not always be obtainable. Hence, we have made it our policy to invite patients back at no extra charge.
Yes, we advise all patients drink at least 1 litre prior to their appointment as this will make it easier to see the baby.
If you have any doctors/hospital notes from your pregnancy, please bring these along to your NT scan as this will assist the sonographer if a referral is needed.
Yes, if your scan indicates anything wrong we will discuss this with you fully and will provide a report you can forward to your GP/health practitioner.
Yes, our services are a complementary service which works alongside the NHS.
We advise all patients to let their GP/midwife know of their intention to have a scan with us. When you arrive at the Ultrasound plus clinic, we will ask you to complete a registration form which will request your GP/midwife details. If your NT scan shows a need to contact or share any information regarding you or your baby, you are responsible for providing the report to your GP/midwife.
You will need to pay for your Ultrasound Plus scan directly and we will provide you with an invoice. We would advise you to check this with your insurance company first, as any claims made are between the patient and the insurance company.
If you would like to bring guests along with you to you NIPT scan, you are more than welcome to bring up to five friends and family.
