Nuchal Translucency Assessment offers assessment for chromosomal anomalies in early pregnancy.
This ultrasound is time sensitive and is best carried out between 12 weeks and 13 weeks 6 days. The test suggests which pregnancies are at a higher risk of abnormality and may need further investigation.
Alongside the scan we require you to have a blood test at least three working days prior. The pathology results and the scan measurements are used together to provide your report.
During the procedure we scan your pelvis with a full bladder (transabdominal scan).
How do I prepare?
Please arrive early for your exam as you will be asked to complete a pre-scan questionnaire.
It’s a good idea to dress in a separate top and bottoms, as this makes accessing your abdomen easier.
We require you to have a full bladder during this scan. Please drink 500ml of water one hour before your appointment and try your best not to empty your bladder. If you think you will find this difficult, please talk to us at the time of booking.
You are not permitted to take photos or video during the scan. This is a medical procedure, and whilst we appreciate you are excited, the health of your baby is our primary concern and we ask for your support and understanding during this clinical appointment.
Due to the medical nature of the appointment we ask that you are accompanied by one person. If you want to bring another child, it’s important to be aware that sometimes an internal examination is also required, and during this, the child will need to leave the room and be supervised.
Technology and Team
Each of our practices use different equipment including Philips and Siemens machines
Your Ultrasound will be performed by a Sonographer. They are specially trained medical professionals who perform ultrasounds. The images the Sonographer captures are then reviewed by a Radiologist who will generate a report for your referring doctor.
What happens during my examination
You will be asked to lie down on a bed and your abdomen will need to be visible. The Sonographer will do their best to protect your clothing as they apply a warmed gel to your abdomen.
This gel helps the Sonographer move the probe over your abdomen and towards the pelvic/ovarian area.
To ensure we capture all the images the Doctor needs, the Sonographer may take up to an hour to complete the scan.
During a Nuchal Translucency Scan the Sonographer will measure the fluid at the back of the baby’s neck. If this area is thicker than normal, it can be an early sign of Down syndrome, trisomy 18 or cardiac problems.
In some cases, a transvaginal ultrasound is also performed. You can read about this part of the procedure here.
The Sonographer and Radiologist will work together during an appointment to ensure all the necessary images are captured. This means that sometimes the Radiologist will come into the room. If this is the case you will be consulted before this happens.
After your examination
The results of your Nuchal Translucency scan will be sent directly to your referring Doctor.
Following completion of this scan you will be counseled regarding the outcome of the tests. Please ensure you book a timely follow-up appointment to discuss your results with them.
As an accredited member of the International Research Programme for Nuchal Translucency Screening, follow up of the outcome of your pregnancy is important. Therefore, we may contact you either by mail or phone for follow-up after you have delivered your baby. Please indicate to us at the time of your examination if you do not wish to be contacted.
