Nuchal Translucency

What you need to do to prepare for an Nuchal Translucency

  • You must have a referral
  • If you have had your blood test done please bring your results with you. We can refer you for this test after your ultrasound if required
  • A full bladder is required for the test
  • Empty your bladder 1 to 1 ½ hours prior to your appointment time
  • Drink 1 litre of water after emptying your bladder
  • Finish drinking your water at least 30 minutes prior to your appointment
  • Do not empty your bladder whilst or after you finish drinking your water. If you are uncomfortable advise our staff upon arrival

What will happen when you have your examination

  • You will lie on a couch for the majority of the test
  • The specialist will apply a water based gel to your skin – this allows the transmission of the sound waves and facilitates movement of the ultrasound probe
  • A written consent may need to be signed if you have a transvaginal ultrasound at the time of your examination
