Clinical Significance. A synthetic circular peptide containing citrulline called CCP IgG (cyclic citrullinated peptide) 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.
Anti-Cyclic Citrullinated Peptide Antibody Test (anti-CCP) - Anti-CCP is a blood test which is now commonly ordered if rheumatoid arthritis is suspected. A moderate to high level of anti-CCP in blood essentially confirms the diagnosis in a person who has clinical signs of rheumatoid arthritis. The anti-CCP test is more specific than the test for rheumatoid factor. In clinical practice, both the rheumatoid factor test and anti-CCP test should be ordered together.
