Test Detail

Cyclic Citrullinated Peptide (CCP) Antibody

Cyclic citrullinated peptide (CCP) antibodies are a type of autoantibody detected by the anti-CCP test to diagnose and monitor rheumatoid arthritis (RA). These antibodies, which target citrullinated proteins often found in joint tissue, are highly specific for RA, with a positive test indicating a high likelihood of the disease and often predicting a more severe course and increased risk of joint erosion. A positive anti-CCP test is a key component in RA diagnosis and can help guide treatment to minimize joint damage and improve outcomes.
