Abstract
Rheumatoid arthritis is a systemic, chronic and inflammatory autoimmune disease characterized by joint inflammation that often leads to joint destruction,RA is the most common inflammatory joint disease in the world (Vallbracht et al,2004. However, especially during the first few months of diseases, the 1987 revised criteria of the ACR are rarely met. So diagnostic tests with high specificity are desirable for choosing the optimal treatment.
