Anti CCP Ab
Anti-CCP is a very useful test to order during the diagnostic evaluation of a person who may have rheumatoid arthritis. If present in such a patient at a moderate to high level, it not only confirms the diagnosis but also may indicate that the patient is at increased risk for damage to the joints. (Low levels of this antibody are less significant).
Purpose of test
This test is primarily ordered along with an RF test when a patient has previously undiagnosed inflammatory arthritis or has been diagnosed with undifferentiated arthritis. It may be ordered as a follow-up test to a negative RF test when clinical signs, such as symmetrical joint pain and inflammation, lead the doctor to suspect RA..
