What is it?

A Doppler duplex test is a special type of ultrasound that examines both blood vessels and blood circulation. The duplex ultrasound looks not only at ultrasound images, but also at the blood's velocity using the Doppler technique. The test can also rule out other causes of leg swelling (e.g. deep vein thrombosis or a deep venous insufficiency due to poorly functioning venous valves).

Course of the procedure

  • You do not have to fast for a Doppler duplex test of your arms or legs.
  • There is no special preparation required.
  • The test is not painful and lasts approximately 15-45 minutes, depending on the area tested.
  • The physician will visualise the area to be tested using an ultrasound probe. You will be told the results immediately.
