Nuchal Translucency Ultrasound
The Nuchal Translucency Ultrasound estimates the risk of your baby having Down’s syndrome. We perform this exam between 12 weeks and 13 weeks, 4 days. It requires that we take a specific measurement of the skin thickness at the back of the neck.
HOW DO I PREPARE FOR MY EXAM?
- Please arrive 15 minutes prior to your appointment.
- Take all prescribed medications as directed.
- Wear comfortable clothes.
- Have a snack and drink one litre of water 60-90 minutes prior to your exam to ensure you arrive with a full bladder.
- If you are too uncomfortable, please relieve your bladder of a small amount of urine.
- Once the test has begun, your sonographer will advise you if you can empty your bladder further or totally. We understand that a full bladder can be uncomfortable.
WHAT HAPPENS DURING MY EXAM?
