ANKLE BRACHIAL INDEX
A quick, noninvasive test to check your risk of peripheral artery disease. This test compares your blood pressure measured at your ankle with your blood pressure measured at your arm. A low ankle-brachial index number can indicate narrowing or blockage of the arteries in your legs.
WHAT TO EXPECT: During this quick test, you lie on a table on your back and a technician measures your blood pressure in your arms using an inflatable cuff. Then, the technician measures the blood pressure in two arteries in both your ankles using the inflatable cuff and a hand-held Doppler ultrasound device. This test lasts approximately 30 to 45 minutes.
