Apart from anti CCP antibody test, rheumatoid factor (RF) test, joint X rays, and blood tests are advised. If a patient has positive anti CCP antibody test as well as RF test it indicates that the patient has rheumatoid arthritis. If the patient has a positive anti CCP antibody test but negative RF test it means that the patient is likely to develop rheumatoid arthritis in the future. If anti CCP antibody test is negative but RF test is positive, it can indicate that the patient should be analyzed for other inflammatory conditions as well.
