Rheumatoid arthritis (RA) is an inflammatory multisystem disease of unknown etiology characterized by chronic destructive synovitis. It’s prevalence is about 1% all over the world. Serologic markers are also important beside some clinical situations upon RA diagnosis. Today, the most commonly used laboratory test is rheumatoid factor (RF) in patients with suspected RA. RF is sensitive but not a specific biomarker for diagnosing RA. Early diagnosis of RA is essential to prevent of progressive joint damage. In recent years, anticyclic citrullinated peptide/protein antibody (anti-CCP) attracts the attention as a remarkable biomarker for early diagnosis. Anti-CCP which is a family of anti-citrullinated protein antibodies (ACPA) family, showed quite satisfactory specificity in the diagnosis of RA. Due to the prescence of ACPA was included to 2010 RA diagnostic criteria, in a manner of speaking, importance of anti-CCP was registered.
