How is rheumatoid arthritis diagnosed?
A diagnosis of rheumatoid arthritis is based upon identification of clinical features, such as swelling of three or more joints for six or more weeks, swelling of the same joints on both sides of the body, and appearance of rheumatoid nodules. Specific laboratory tests can also be used to diagnose rheumatoid arthritis or inflammation.
