The Ankle-Brachial Index (ABI) test evaluates leg blood flow by comparing ankle and arm blood pressure. A technician measures blood pressure in both areas using a cuff and ultrasound. A normal ABI ranges from 0.9 to 1.3. Lower values may signal leg artery blockage, indicating peripheral artery disease (PAD), while higher values may suggest artery stiffness. This non-invasive test helps diagnose circulation issues in the legs, guiding necessary treatment to prevent complications.

NOTE: An ABI Test can give a FALSE normal result if:

1. You have diabetes and/or chronic kidney disease

2. Heavy calcification in your arteries.

​

If you have diabetes and/or are experiencing pain or cramping in your calf region.

If you have a normal result and you still have leg pain/cramping:

Say, "Hey Doctor, please order me a Duplex Ultrasound to make sure I don't have heavy calcification giving us a false normal result."
