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.
What does an ABI tell you?
An ankle-brachial index (ABI) test is a simple way for your doctor to check how well your blood is flowing in your legs. Doctors use this test to check for peripheral artery disease (PAD). When you have this condition, it means you have blockages in the arteries of your arms and legs.
What does an abnormal ABI mean?
