An ankle-brachial index test or ABI testis is a quick and noninvasive test to know if you have peripheral artery disease (PAD). A low ABI means arteries in the legs may be blocked, increasing the risk of heart attack or stroke.
Ankle-Brachial Index (ABI) Testing
Who needs an ABI test?
You may need an ABI test if you have:
- Leg pain, cramping, or weakness when walking
- Non-healing wounds or ulcers on your legs or feet
- Cold or discolored feet
- A history of smoking, diabetes, high blood pressure, or high cholesterol
- A family history of vascular disease
How does it work?
An ABI testing compares blood pressure in the ankle and arm to check for PAD (peripheral artery disease). It’s fairly quick and painless. Plus, you don’t have to do any special preparations before getting the test.
Your healthcare provider will check the blood pressure of specific arteries in your arms and your ankles. They will use an inflatable cuff and an ultrasound device to listen to the blood flow in the arteries they are using to check your blood pressure.
