LP16738-4   Rheumatoid factor
Rheumatoid factor (RF or RhF) is a blood test performed in patients with suspected rheumatoid arthritis (RA). It is an auto-antibody directed against the Fc portion of IgG, which is itself an antibody. RF and IgG form immune complexes, which are part of the disease process (serum sickness) of various rheumatological diseases. Storage/Transport Temperature: 1 mL plasma or serum, 2-8°C. (Min: 0.2 mL) Submit specimen in an ARUP Amber Transport Tube. Rheumatoid factor can also be a cryoglobulin (antibody that precipitates on cooling of a blood sample); it can be either type 2 (monoclonal IgM to polyclonal IgG) or 3 (polyclonal IgM to polyclonal IgG) cryoglobulin.
