[Expert consensus on clinical detection of rheumatoid arthritis related autoantibodies]

Rheumatoid arthritis (RA) is a common chronic and systemic autoimmune disease. Early diagnosis and standard treatment are the keys to control the disease and improve the prognosis. A variety of autoantibodies such as rheumatoid factor and anti-citrullinated peptide/protein antibodies can be detected in serum of patients with rheumatoid arthritis, which are important for early diagnosis and differential diagnosis of RA, judgment of disease severity and prognosis evaluation. The standardization of autoantibody detection related to rheumatoid arthritis is very important for its clinical application. Under the organization of the Committee of the Autoantibodies Detection of Rheumatology and Immunology Physicians Committee of Chinese Medical Doctor Association, expert consensus on clinical application of rheumatoid arthritis related autoantibodies detection were established by a joint group of Chinese multi-disciplinary experts. The consensus aims to standardize the detection of RA associated autoantibodies, and to provide a reference for clinicians and laboratory technicians to use and interpret rheumatoid arthritis-related autoantibodies in daily practice.
