What are the tests for polymyalgia rheumatica?

None, really. There are no tests that prove you have it, but typically your doctor will check your inflammatory markers (esr/crp) and other tests to rule out other possibilities.
Blood tests. 1)sed rate, or erythrocyte sedimentation rate (esr) 2)c-reactive protein test 3)ultrasound imaging, which uses sound waves to produce images of soft tissues, may reveal inflammation of tissues within the shoulder and hip joints that can support a diagnosis of polymyalgia rheumatica.
