Your doctor may think you have PAD because of your symptoms and your health history. Other signs, such as a weak pulse in your legs, may be found during an exam.
PAD is often confirmed with an ankle-brachial index (ABI) test. Blood pressure is measured in arteries at the elbow and ankle. This is done with a blood pressure cuff and ultrasound. The readings are compared in a ratio. If the ratio is lower than it should be, it is a sign of a problem with blood flow in the legs. If you have an irregular ABI test, your doctor may order a treadmill test to check your ability to walk.
