Diagnosis of Peripheral Artery Disease (PAD)
The doctor will ask about symptoms and health history. Other signs, such as a weak pulse in the legs, may be found during a physical exam. This may be enough to suspect PAD.
PAD is often confirmed with an ankle-brachial index (ABI) test. This measures blood pressure in arteries at the elbow and ankle. It 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. A treadmill test may be done on people who have an irregular ABI to check their ability to walk.
