Ankle-Brachial Index (ABI) Testing

An ABI test is a simple, reliable test for diagnosing PAD in the legs. The test measures the blood pressure in your ankles and compares it to that in your arms. If the blood pressure is lower in your legs than in your arms, it may indicate that PAD is restricting blood flow in your legs. The ABI test is fast and painless, and does not require entering the body.
