New research shows that an extended autoantibody repertoire is associated with adverse clinical outcomes in patients with rheumatoid arthritis. Testing for rheumatoid factor and antibodies against citrullinated proteins is now routine in the evaluation of patients with rheumatoid arthritis; should this testing be extended to include other classes of autoantibody?
