The Anti-ds-DNA IgA/IgG/IgM Screen ELISA is a solid phase enzyme immunoassay with human recombinant double-stranded DNA (dsDNA) for the quantitative and qualitative detection of IgG, IgA, and IgM antibodies against dsDNA in human serum. Anti-dsDNA antibodies mainly recognize the phosphate units of DNA, thus these autoantibodies also bind single stranded DNA (ssDNA). To ensure correct quantitation of anti-dsDNA antibodies the antigen used in the kit has been proven to be free of contamination with ssDNA. The assay is a tool for the study of systemic lupus erythematosus (SLE).

Most individuals with SLE display IgG class antibodies against dsDNA. These autoantibodies are associated with lupus nephritis. In addition, approximately 30% of individuals with SLE develop IgA class anti-dsDNA antibodies. It has been suggested that the presence of these IgA class antidsDNA antibodies may define a certain subset of individuals with SLE. Studies demonstrated the association of this subclass with certain parameters of the disease activity, such as elevated erythrocyte sedimentation rate, or the consumption of complement component C3, as well as the clinical parameters of cutaneous vasculitis, acral necrosis, and erythema. No association was found for nephritis and arthritis.
