Order Rheumatoid Factor (RA) Test - ArthritisThe Rheumatoid Factor (RA) Test detects and measures rheumatoid factor, an autoantibody that the immune system can produce against its own tissues. Although the name ties it closely to rheumatoid arthritis, rheumatoid factor is not exclusive to that condition, and its presence alone does not confirm a diagnosis. The test is one piece of a broader clinical picture that includes symptoms, physical examination, and other laboratory findings.
About Rheumatoid Factor (RA) Test - Arthritis in Carmichael
Rheumatoid factor is an antibody directed against the Fc portion of immunoglobulin G, and it exists in several isotypes, most notably IgM, IgA, and IgG.
The classic assay measures rheumatoid factor of the IgM class, which is the form most commonly detected in clinical laboratories. Elevated levels of IgA and IgG rheumatoid factor have also been reported in people with rheumatoid arthritis, and these isotypes are sometimes evaluated in research or specialized settings.
Rheumatoid factor can be present in a number of conditions beyond rheumatoid arthritis, including several other autoimmune diseases, chronic infections, and some liver diseases. It is also found in a proportion of healthy individuals, particularly as age increases, which is why a positive result must be interpreted alongside the clinical presentation rather than in isolation.
Because rheumatoid factor is neither perfectly sensitive nor perfectly specific for rheumatoid arthritis, clinicians often combine it with other markers and imaging. A negative result does not rule out rheumatoid arthritis, and a positive result does not by itself establish the diagnosis. Results are most useful when considered in the context of a person's symptoms and overall health history.
