An ABI is a non-invasive test used to check for how well blood is flowing throughout a patient’s body, specifically through the arms and legs.

The ABI compares the blood pressure at the ankles to the blood pressure at the arm.

This test is generally done to check for the presence or severity of Peripheral Artery Disease or PAD.

A normal ABI resting result is 1.0 to 1.4 where a value of 0.9 and lower or 1.4 and higher is considered abnormal. Abnormal results may mean that you have a higher chance of narrowed arteries.

Generally, if patients receive abnormal or borderline abnormal ABI results our doctors will order an ultrasound to confirm and further identify the severity of the vascular disease and the exact location and blockage type. This allows them to better plan their treatment plan for each patient.
