The purpose of an Ankle Brachial Index is to evaluate blood flow to your legs. This non-invasive test enables your cardiologist to determine if there is any narrowing or restriction of an artery or blood vessel that reduces blood flow, how serious the blockage is and exactly where it is located. This test is done by measuring blood pressure at the ankle and in the arm while a person is at rest.

Following are some frequently asked questions about the test and how to prepare for it. Click on the question for the answer, which will appear below the questions.



What will happen during the test?

The stress technician will start by taking or reviewing your medical history. You will be asked to lie on your back while standard blood pressure cuffs are placed around your ankles and arms. The cuffs will be inflated and a small ultrasound probe will be placed against the leg. As the cuffs are deflated waveforms will be documented assessing blood flow.
