Anti-citrullinated peptide antibody (ACPA) assays, developed and commercialized in the past decade, are now being employed clinically. Since ACPA are present before the onset of RA symptoms and are predictive of RA development, they are a valuable diagnostic test early in the course of the disease (4).
What is ACPA positive RA?
Rheumatoid arthritis (RA) is associated with HLA-DRB1 shared epitope (HLA-DRB1SE) and anti-citrullinated protein autoantibodies (ACPAs). ACPAs precedes the onset of clinical and subclinical RA.
What is the normal range for cyclic citrullinated peptide?
Anticyclic Citrullinated Peptide The normal level of anti-CCP is less than 20 Units. (At Hospital for Special Surgery, anti-CCP is reported in Units. Some labs report this same result using a different measurement notation, that is, as less than 20 EU/ml.) A level above 20 suggests the possibility of RA.
