Highly specific serologic test that aids in the workup of suspected rheumatoid arthritis or undifferentiated inflammatory arthritides. Rheumatoid Arthritis Panel (2003277) is preferred test.
Semi-Quantitative Enzyme-Linked Immunosorbent Assay
Within 24 hours
Serum separator tube.
Separate serum from cells ASAP or within 2 hours of collection. Transfer 0.5 mL serum to an ARUP Standard Transport Tube. (Min: 0.3 mL)
Urine or plasma. Contaminated, hemolyzed, grossly icteric, heat-inactivated, or severely lipemic specimens.
After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)
|19 Units or less||Negative|
|20-39 Units||Weak positive|
|40-59 Units||Moderate positive|
|60 Units or Greater||Strong positive|
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.
No compliance statements are in use for this test.
