Ankle/Brachial Index (ABI)

What is it for?

The ankle/brachial index (ABI) is a measurement taken to predict the severity of arterial disease in the legs.

How is it done?

Several blood-pressure measurements are taken at rest at the ankles, at other locations on the legs, and the arms. The measurements may also be repeated after a brief period of exercise on the treadmill. If the ABI measurements are abnormal at rest or decrease after exercise, it may be an indicator of peripheral artery disease.

What happens after the test?

The health-care provider who administers the test will send the results to the referring doctor, who will determine if any treatment is necessary.
