Anti-CCP is also very useful in the early diagnosis of rheumatoid arthritis in high-risk groups, such as relatives of RA patients, [19] although Silman and co-workers found that the concordance rate of developing RA was 15.4% among identical (monozygotic) twins and was 3.6% among fraternal (dizygotic) twins.
The sensitivity of RF for established rheumatoid arthritis is only 60 to 70 percente with a specificity of 78 percent. [8] Rheumatoid factor is part of the 2010 ACR/EULAR classification criteria for rheumatoid arthritis. RF positivity combines well with anti-CCP and/or 14-3-3η to inform diagnosis. [9]
In rheumatoid arthritis and other autoimmune diseases, such as psoriatic arthritis, systemic lupus erythematosus and Sjögren's syndrome, autoantibodies often attack citrullinated proteins. The presence of anti-citrullinated protein antibody is a standard test for rheumatoid arthritis, and it is associated with more severe disease.
When RA is clinically suspected, a physician may test for rheumatoid factor (RF) and anti-citrullinated protein antibodies (ACPAs measured as anti-CCP antibodies). [ 76 ] : 382 The test is positive approximately two-thirds of the time, but a negative RF or CCP antibody does not rule out RA; rather, the arthritis is called seronegative , which ...

Anti-MCV antibodies are a member of the ACPA family, a group of the so-called antibodies to citrullinated protein/peptide antigens. Rheumatoid arthritis is an autoimmune disorder. Detection of specific autoantibodies (antibodies directed against the body’s own tissue) such as rheumatoid factors and ACPAs may provide indication of the disease.
