If the ESR and CRP test results are normal, it’s unlikely that polymyalgia rheumatica will be diagnosed.
Sometimes the ESR may be normal and the 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 feature of many conditions, high levels don't automatically mean 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.
