Get StartedWhat you can expect
By Mayo Clinic staffYou lie on a table on your back, and your doctor measures your blood pressure in both your arms using an inflatable cuff. Then, your doctor measures the blood pressure in two positions in your left ankle using the inflatable cuff and a hand-held Doppler device that your doctor will press on your skin. The Doppler device lets your doctor hear your pulse in your ankle arteries after the cuff is deflated.
The procedure for performing an ankle-brachial index test may vary slightly, based on your doctor's preference.
Having an ankle-brachial index test is painless and similar to getting your blood pressure taken in a routine visit to your doctor. You may feel some pressure on your arm or ankle when the cuff inflates to read your blood pressure.
