Normal values for anti-double-stranded DNA antibodies, for radioimmunoassay, are less than 20% binding in healthy humans. Anti-double-stranded DNA antibodies are one of the DNA antibodies and are a serum marker for SLE. Moreover, anti-double-stranded DNA antibodies are mainly found in the sera of SLE patients and have a pathogenic effect on tissue and organ damage in SLE patients. Its specificity of detection reaches about 90%-60%, and it is a marker of SLE activity, which rises and falls with the activity of SLE disease, and the titer will drop or turn negative if the disease improves.
