Ankle Brachial Index (ABI)

The ABI is a screening test for the assessment for the presence of PAD.

• Ratio of the ankle blood pressure divided by the highest brachial blood pressure
• Normal is 0.9 to 1.3
• The exercise ABI is done by having the patient stand on their toes repeatedly as exercies. The ABI is rechecked after exercise. This test is done if the patient has symptoms with exercise and a normal ABI at rest.
