Ankle-Brachial Index (arterial Doppler)
This test is intended to work out whether the arteries in your legs are clear or not. This can be done by comparing two blood pressures in your arm and ankle. If the blood pressure in the ankle is significantly lower, this is due to a narrowed artery in the leg.
What happens during the test
- You will be lying down on an examination table.
- A hand-held Doppler scanner is used to measure the speed of the blood flow. This is completely painless.
- The test takes about 10 to 15 minutes.
