Blood Tests
Many blood tests can be used to confirm the presence of rheumatoid arthritis. For instance, CRP or C-reactive protein is a test that would determine the levels of inflammation caused by the condition in your body. Similarly, your doctor can take an ESR or erythrocyte sedimentation rate test to measure some inflammatory activities. Another option is the full blood count, which would rule out many potential causes of rheumatoid arthritis and provide an overall indicator for your general health. [2]
