About Rheumatoid Factor (RA) Test - Arthritis in Carson
Rheumatoid factor testing is a blood test used to detect and measure autoantibodies that target the body's own antibodies, most commonly the immunoglobulin M class.
Rheumatoid factor is not a single substance but a family of autoantibodies, with the IgM class being the one most frequently measured in routine testing. Elevated levels of IgA and IgG rheumatoid factor have also been reported in people with rheumatoid arthritis, though these are less commonly assessed in standard laboratory practice.
The test is most useful when interpreted in context. A positive result does not by itself confirm rheumatoid arthritis, and a negative result does not rule it out. Rheumatoid factor can be present in other conditions, including certain infections and other autoimmune diseases, and it can appear in some people who have no related illness at all.
Because of this, clinicians typically combine rheumatoid factor results with a person's medical history, joint examination, and other tests. The test's role is to add supporting evidence, not to stand alone as a diagnosis.
