Methods for providing a population of bioparticles, modifying the bioparticles to permanently and detectably tag each bioparticle to give tagged bioparticles, forming an internal quality control sample of a defined quanta of tagged bioparticles in a defined volume of carrier, adding the control sample to an assay sample for the detection of the same bioparticles, carrying out said assay, and thereafter determining the proportions of tagged bioparticles so detected in the assay sample as a measure of assay accuracy are described. Also described are methods for providing an internal quality control in the analysis of bioparticles in potable fluids, and internal quality control standards.
