Ankle Brachial Index (ABI)
During a PAD screening, patients are asked to lie flat on their back on the exam table with their socks and shoes off. The technologist will measure the blood pressure at the ankles and in both arms. A ratio of the ankle to arm pressures is calculated to determine the ankle-brachial index (ABI). The ABI is used to determine the presence or absence of peripheral arterial disease.
This is a painless, non-invasive procedure.
