Polymyalgia rheumatica
Diagnosing polymyalgia rheumatica (PMR) can often be quite a lengthy process that involves several different tests.
This is because the condition shares many symptoms with more common health conditions, such as Rheumatoid arthritis , which need to be ruled out first.
There's no specific test for polymyalgia rheumatica, but it's likely that a series of blood tests will be carried out.
Two blood tests erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) can be used to check the levels of inflammation in your body.
If the ESR and CRP test results are normal, its unlikely that polymyalgia rheumatica will be diagnosed because your doctor wont want to prescribe a long-term course of steroids if the diagnosis is uncertain. Sometimes, the ESR may be normal and CRP may be raised, which would be more likely to indicate a positive diagnosis. This is why both tests are usually carried out at the same time.
As inflammation is a characteristic of many conditions, high levels don't automatically mean that you have polymyalgia rheumatica. Further tests may be needed to help rule out other conditions that cause inflammation. For example, a test for rheumatoid factor and anti-CCP antibodies , may be carried out to rule out rheumatoid arthritis.
