Rheumatoid Factor ELISA Kit

Rheumatoid Factors are the best-known diagnostic markers for rheumatoid arthritis (RA), and presence of rheumatoid factors is an integral part of the current ACR criteria for classification of RA. Rheumatoid factors are a subcategory of immunoglobulins that specifically bind to the Fc regions of IgG.

Elevated concentrations of rheumatoid factors are often correlated with a more severe course of the disease. IgM RF may precede the onset of RA by several years. In established RA, high titer serum IgM RF indicate poor prognosis. The presence of either IgG or IgA RF in patients with long-standing RA may be a prognostic indicator of systemic manifestations.

For more extensive serological diagnosis, monitoring of treatment, and early diagnosis of rheumatoid arthritis, we recommend our Anti-MCV ELISA.
