Clinical Significance: A synthetic circular peptide containing citrulline called cyclic citrullinated peptide (CCP) IgG has been found to be better at discriminating rheumatoid arthritis patients from other patients than either the perinuclear autoantibody test or the test for rheumatoid factor. Approximately 70% of patients with rheumatoid arthritis are positive for Anti-CCP IgG, while only about 2% of random blood donors and disease controls subjects are positive.
Limitations: The presence of immune complexes may cause false-positive results due to increased non-specific binding.
