Preferred panel for the workup of suspected rheumatoid arthritis or undifferentiated inflammatory arthritides.
Semi-Quantitative Enzyme-Linked Immunosorbent Assay/Immunoturbidimetry
Within 24 hours
Fasting specimen preferred.
Serum separator tube.
Allow serum to clot completely at room temperature before centrifuging. Transfer 2 mL serum to an ARUP Standard Transport Tube. (Min: 1 mL) Serum is the only acceptable specimen type for this assay without a disclaimer.
Urine or plasma. Contaminated, heat-inactivated, hemolyzed, icteric, or severely lipemic specimens.
After separation from cells: Ambient: 24 hours; Refrigerated: 1 week; Frozen: 1 month (avoid repeated freeze/thaw cycles)
Anti-cyclic citrullinated peptide (anti-CCP) IgG antibodies are present in about 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.
