Anti-cyclic citrullinated peptide (anti-CCP) is an antibody present in most rheumatoid arthritis patients. Levels of anti-CCP can be detected in a patient through a blood test. A positive anti-CCP test result can be used in conjunction with other blood tests, imaging tests, and physical examinations to reach a rheumatoid arthritis diagnosis.
It is performed to confirm Rheumatoid Arthritis and also during the treatment and after the treatment of Rheumatoid Arthritis.
The normal level of anti-CCP is less than 20 u/ml. A level above 20 suggests the possibility of RA.
