What is an Ankle-Brachial Index/ABI Test?
An ankle-brachial index (ABI) is a form of blood pressure monitoring conducted on the legs to screen for peripheral arterial disease (PAD).
What is Peripheral Artery Disease?
Peripheral artery disease is a condition where the arteries in your arms and legs have become narrowed or blocked. A decreased ankle-brachial index result is an indicator that a patient may have peripheral artery disease.
How is an Ankle-Brachial Index Performed?
To begin, please ensure that you’ve followed our patient checklist:
- Bring all current medications to the appointment
- Do not wear any perfumes or colognes on the day of the appointment
Once arrived, the patient’s blood pressure is taken below the knee, and on the upper arm using blood pressure cuffs.
The blood pressure in the leg is compared to the blood pressure in the arm
(BPleg / BParm). The lower the resulting number is, the greater risk a patient is at for having peripheral artery disease.
