What is your abi? what does this value tell you about your risk of peripheral artery disease?

ABI means Ankle-Brachial Index. ABI is a test used to diagnose peripheral artery disease. The ABI compares blood pressure in the ankle to blood pressure in the arm, shows how well blood is flowing in the limbs and indicates if there is any or no blockage or rigid arteries. The amount of blockage establishes the level of peripheral artery disease.
