AbstractWe compared the FIAX fluorometric immunoassay for antiDNA antibodies with a Farr radio‐immunoassay. Neither was precise; coefficients of variation usually exceeded 10%. The 2 assays correlated well (r = 0.87). Both were almost completely specific for systemic lupus erythematosus and identified similar numbers of sera with elevated antiDNA levels. FIAX was faster, simpler, and safer. It appears preferable to the Farr assay and probably to all other antiDNA assays currently used in clinical situations, although its reproducibility needs improvemen
