Abstract:
Background fluorescence which interferes with the measurement of an analyte in fluorescent immunoassays in serum samples is substantially diminished by treating the serum sample with a sufficient amount of a peroxidic compound, either organic or inorganic, for a time sufficient to reduce the background fluorescence contributed by serum components. The peroxidic compound is readily quenched, without adversely affecting the assay composition.
