Anti-cyclic citrullinated peptide (anti-CCP), IgG antibodies are present in 69-83 percent of patients with rheumatoid arthritis (RA) and have specificities of 93-95 percent. These autoantibodies may be present in the preclinical phase of disease, are associated with future RA development, and may predict radiographic joint destruction. Patients with weak positive results should be monitored and testing repeated.

The Anti-Nuclear Antibody test was performed by the indirect immunofluorescence technique using the Hep-2 substrate slides and the anti-Human IgG conjugate, fluorescein labeled.
