Ankle Brachial Index

​The CLPCN Nurse can provide an ankle-brachial index (ABI) as a quick non-invasive way to check your risk of peripheral artery disease (PAD).

PAD occurs when narrowed arteries reduce the blood flow to your limbs. PAD can cause leg pain when walking and increases the risk of heart attack and stroke.

The ABI compares blood pressure in your ankle to blood pressure in your arm. This test shows how well blood is flowing in your limbs.

This test requires a referral from your Primary Provider. It may be indicated if you have leg pain while walking or have risk factors for PAD, such as:

  • History of tobacco use

  • Diabetes

  • High blood pressure

  • High cholesterol

  • Restricted blood flow (atherosclerosis) in other parts of your body
