Disclosed herein are methods for the chemiluminescent assay of a variety of analytes of interest. The methods are adaptable to the determination of microbial species in both liquid samples and on solid surfaces. The disclosed methods can be used with rapid, self-contained chemiluminescence assay devices, or can be used with novel sampling devices and conventional microbial analysis techniques involving growth of microbial samples on appropriate culturing media. The specificity of the methods can be enhanced with the use of immunospecific reagents. The sensitivity of the technique can be increased by 3 to 6 orders of magnitude by first converting all DNA in the sample to inorganic phosphates before generating the emission signal. The breadth of applicability of the disclosed methods can be enhanced through the selection of appropriate enzyme-catalyzed reactions where one of the products of enzymatic oxidation is hydrogen peroxide.
