Frequently Asked Questions
The Ankle-Brachial Index (ABI) is a ratio of blood pressure in the lower legs to that in the arms, used to screen for peripheral artery disease (PAD).
ABI is calculated by dividing the systolic blood pressure at the ankle by the higher of the two arm systolic pressures. The lower of the two ankle pressures is used for the final result.
An ABI below 0.9 indicates peripheral artery disease, while above 1.4 may suggest non-compressible arteries. Consult a healthcare provider for proper diagnosis.
