To demonstrate the medical diagnosis of rheumatoid arthritis (RA), cyclic-citrullinated peptide (CCP), one of specific antigens against RA autoantibodies, was immobilized on the surface of the immunostick, and a color index table was prepared for the determination of CCP-positivity of the test sera. The positivity of RA-positive (n = 31) and RA-negative (n = 20) sera was tested using the immunostick assay and a conventional enzyme-linked immunosorbent assay (ELISA). The statistical agreement of the test results from both methods was analyzed using inter-rater coefficient kappa and Bland-Altman test. The immunostick assay with a color index table was determined to have a high statistical correlation to the conventional ELISA method.
