Although RF is most closely associated with rheumatoid arthritis, it also appears in other conditions and in some people without any disease at all. Understanding what the test detects, and what it does not, helps put a result in context.
About Rheumatoid Factor (RA) Test - Arthritis in Lebanon
Rheumatoid Factor is an antibody directed against the Fc portion of immunoglobulin G, and it exists in several classes, most commonly IgM.
The classic RF assay detects IgM rheumatoid factor, the form most often elevated in rheumatoid arthritis. Because IgM RF can also be found in healthy individuals and in infections, autoimmune diseases, and other inflammatory states, a positive result alone does not confirm rheumatoid arthritis.
Beyond IgM, RF of the IgA and IgG classes has been reported at raised levels in people with rheumatoid arthritis. These additional isotypes are not part of routine RF screening, but they illustrate that the autoantibody response in RA is broader than a single immunoglobulin class.
Clinicians interpret RF alongside symptoms, physical findings, and other laboratory markers such as anti-cyclic citrullinated peptide (anti-CCP) antibodies. Serial measurements may be used to track disease activity over time, though the test is not a stand-alone diagnostic tool.
