Ankle-Brachial Index

The Ankle-Brachial Index (ABI) is a simple test used to assess blood flow and detect peripheral artery disease (PAD). It compares the blood pressure in your ankle with the blood pressure in your arm. By measuring these pressures, doctors can see if there is a significant drop in blood flow to the legs, which may indicate narrowed or blocked arteries. A lower ABI value suggests poorer blood circulation, potentially leading to complications. The test is non-invasive, quick, and helps guide further treatment or lifestyle changes to improve vascular health.
