Ankle Brachial Index

14 May 2021

Peripheral arterial disease (PAD) is a disorder of blood supply obstruction to the lower or upper extremities, with increasing prevalence globally. One of the examination for diagnosing PAD is the Ankle-Brachial Index (ABI), which is used for assessing difference in blood pressure between upper extremities and lower extremities.

Normal ABI is ranged between 1.00-1.40, while ABI lower than 0.90 is an indicator of abnormally low bloodflow within the lower extremity that is examined. This result is diagnostic for lower extremity PAD. ABI above 1.40 is abnormally high. High ABI may indicates vascular stiffness that is most often found in elderly patients.
