What are the tests for intermittent claudication?

ABI/PVR: The easiest test is an ankle brachial index which is a comparison between the arm pressure and the calf or ankle pressure. Values in the range of 0.9-1.0 are usually normal. Patients that claudicate usually have values less than that. Please see a vascular specialist.

Vascular lab: Claudication has very low risk of amputation less than 0.5% so sometimes physical exam is enough. But if it became severe and require intervention then non-invasive vascular tests including duplex ultrasound, ankle brachial index and pulse volume recording are the best to start with.
