Ankle Brachial Index (ABI): A Simple Test for Better Leg and Heart Health

The Ankle Brachial Index (ABI) is a quick, painless, and non-invasive test that helps check blood flow in your legs. It’s one of the easiest ways to detect Peripheral Artery Disease (PAD)—a condition where narrowed arteries reduce circulation to your legs and feet.

How the Test Works
ABI compares your blood pressure at the ankle with your blood pressure at the arm. If the pressure is lower in your legs, it may suggest narrowed or blocked arteries.

Why ABI Matters
A low ABI result may indicate poor circulation, which can lead to:

  • Leg pain when walking

  • Slow or poor wound healing

  • Increased risk of heart attack, stroke, or even limb loss

Who Should Get an ABI Test
This test is especially important if you:

  • Have diabetes

  • Have a history of smoking

  • Experience leg pain, cramping, or numbness

  • Have risk factors for heart disease

Early Detection Leads to Better Outcomes
PAD can develop silently, without noticeable symptoms. ABI testing helps identify problems early so that we can create a care plan to improve circulation, reduce symptoms, and lower your risk of serious complications.
