Are there good tests for rheumatoid arthritis?

Yes: The anti-ccp antibody and rheumatoid factor are the best and are positive in 85% of people with rheumatoid arthritis. A good history and examination by a physician experienced with rheumatoid arthritis is the only real way to make the diagnosis.

Yes.: The best tests are a thorough history and physical examination (h&p) by a rheumatologist. Blood tests such as the rheumatoid factor and cyclic citrinullated peptides are helpful but not as reliable as the the h&p. X-rays help less unless there is already joint damage.

Yes: I still mostly rely on the patient’s history and physical exam. A few blood tests can help support a diagnosis of RA: anti CCP antibody, RF for example. If these are present it suggests a worse prognosis. Joint x rays with early symptoms are often normal. More studies are defining the role of musculoskeletal ultrasound and MRI of the joints in helping us diagnose rheumatoid arthritis early.
