Order Rheumatoid Factor (RA) Test - ArthritisThe rheumatoid factor test detects an autoantibody that the immune system can produce against its own tissues, most notably in rheumatoid arthritis.

About Rheumatoid Factor (RA) Test - Arthritis in Ives Estates
Rheumatoid factor is an antibody directed against the Fc portion of immunoglobulin G, and it exists in several classes, including IgM, IgA, and IgG.
The classic assay measures rheumatoid factor of the IgM class, while IgA and IgG rheumatoid factor can also be elevated in people with rheumatoid arthritis. This explains why a panel may report more than one isotype and why results are not interchangeable between methods.
Rheumatoid factor is present in a substantial proportion of adults with rheumatoid arthritis, but it also appears in other autoimmune diseases, chronic infections, and in some healthy individuals, particularly with advancing age. A negative result therefore does not exclude rheumatoid arthritis, and a positive result does not confirm it.
Because of this overlap, the test is used as one piece of a broader assessment. Clinicians combine it with history, joint examination, inflammatory markers, and imaging, and may order anti-cyclic citrullinated peptide antibodies, which are more specific for rheumatoid arthritis.
