Antibodies directed to cyclic citrullinated peptides anti-CCP are highly specific for rheumatoid arthritis RA and can easily be detected in sera by using commercially available immunoassays. The second version of the anti-CCP test anti-CCP2 demonstrated high specificity 89-98% and good sensitivity 41-88% for RA. Commercially available ELISA methods from three different companies are on the market. All three CCP2 assays show similar results as all CCP2 assays use the same antigen-coated plates. This study was an evaluation of a new automated method for the determination of anti-CCP2 in a routine laboratory setting. Five hundred and fourty three serum samples were tested for anti-CCP2 within normal routine diagnostic using a commercially available ELISA and retested with a prelaunch version of a new and fully-automated method EliA™. The results were comparable. The new automated assay is easy to use and demonstrated a diagnostic sensitivity of 80% and specificity of 97%.
