About Rheumatoid Factor (RA) Test - Arthritis in Oxnard
Rheumatoid factor is an antibody directed against the Fc portion of immunoglobulin G. It exists in several classes, most commonly IgM, but IgA and IgG rheumatoid factors also occur.
The presence of rheumatoid factor is not exclusive to rheumatoid arthritis. It can appear in other autoimmune conditions, in some chronic infections, and in a proportion of healthy individuals, particularly as age increases.
In rheumatoid arthritis, higher rheumatoid factor levels tend to correlate with more aggressive joint disease and a greater likelihood of extra-articular involvement, though this relationship is not absolute for any single patient.
Because rheumatoid factor lacks perfect specificity, it is typically interpreted together with anti-cyclic citrullinated peptide antibodies, inflammatory markers, and the clinical examination rather than as a stand-alone diagnostic test.
