The ankle-brachial index test is a quick, noninvasive way to check for peripheral artery disease (PAD). The disease occurs when narrowed arteries reduce the blood flow to your limbs. PADcan cause leg pain when walking and increases the risk of heart attack and stroke. The ankle-brachial index test compares the blood pressure measured at your ankle ...
The ankle-brachial index test is done to check for PAD — narrowed arteries that reduce blood flow, usually in your legs. Research indicates that PADaffects about 10 percent of people over age 55. Your doctor might recommend an ankle-brachial index test if you have leg pain while walking or risk factors for PAD, such as: 1. History of tobacco use 2....
You may feel some discomfort when the blood pressure cuffs inflate on your arm and ankle. But this discomfort is temporary and should stop when the air is released from the cuff. If you have severe leg pain, your doctor may recommend a different imaging test of the arteries in your legs.
No special preparations are needed for an ankle-brachial index test. The test is painless and similar to getting your blood pressure taken in a routine visit to your doctor. You might want to wear loose, comfortable clothing that allows the technician performing your ankle-brachial index test to easily place a blood pressure cuff on your ankle and ...
During the procedure
You likely will be asked to rest for 5 to 30 minutes before the test. Typically, you lie on a table on your back, and a technician measures your blood pressure in both arms and both ankles, using an inflatable cuff and a hand-held ultrasound device that's pressed on your skin. The device uses sound waves to produce images and allows your pulse to be heard in your ankle arteries after the cuff is deflated.
After the procedure
The ankle-brachial index test should take only a few minutes. You don't need to follow any special precautions afterward. Your doctor will discuss your test result with you.
Your doctor uses the blood pressure measurements from your arms and ankles to calculate your ankle-brachial index. Based on the number your doctor calculates, your ankle-brachial index may show you have: 1. No blockage (1.0 to 1.4). An ankle-brachial index number in this range suggests that you probably don't have PAD. But if you have symptoms of P...
The ankle brachial index, or ABI, is a simple test that compares the blood pressure in the upper and lower limbs. Health care providers calculate ABI by dividing the blood pressure in an artery of the ankle by the blood pressure in an artery of the arm. The result is the ABI.
Feb 26, 2021 · An ABI ratio between 0.9–1.4 that is correlated with a multiphasic waveform (e.g., triphasic or mild biphasic) is consistent with a patient who does not have arterial occlusion. An ABI between 0.7–0.9 should correlate with biphasic waveforms (e.g., mild or weak biphasic). These waveforms have a sharp upstroke to the peak and one pit.

Measuring and Understanding the Ankle Brachial Index (ABI) The Ankle Brachial Index (ABI Test) is an important way to diagnose peripheral vascular disease. The index compares the systolic blood pressures of the arms and legs to give a ratio that can suggest various severity of peripheral vascular disease.
