Ankle to Brachial Index “ABI”

An ankle to brachial index or “ABI” measures your blood pressure in both your arms and ankles. Your blood pressure in your ankles is compared to the blood pressure in your arms to screen for peripheral artery disease (blockages or narrowing of the arteries supplying the legs). 

Why the Test is Performed:  Your physician may have ordered an ankle to brachial index to evaluate leg pain and / or to rule out peripheral artery disease. 

Prep: No prep

What to Expect:  You will be asked to remove your socks and shoes, and to lie on your back during the test. Blood pressure cuffs will be placed around your arms and ankles and inflated. A Doppler transducer will be utilized to record your blood pressure in both arms and both ankles. The test will take approximately 30 to 45 minutes to complete. You may resume your normal activities upon complete of the test.
