The anti-cyclic citrullinated antibody test depicts a blood test to detect anti-CCP antibodies in the bloodstream. Anti-CCP test is prescribed to find rheumatoid arthritis as well as to diagnose the type of arthritis including the prognosis. The Anti-CCP antibodies are auto-antibodies which are produced by the patient's own immune system in response to perceived foreign threats from citrulline. In case of rheumatoid arthritis, arginine is converted into citrulline to initiate an inflammatory process in joints. Citrullinated peptides or proteins are not normally found in the body so the immune system starts attacking them. The problem arises when citrullinated peptides exist in the joints and thus become involved in immune response. Generally, the symptoms of rheumatoid arthritis include stiff joints which make it tough to walk or even hold any object during the morning or when the body has rested for some time. Additionally, joint pains, fatigue and low-grade fever are also observed.
