Abstract
This invention relates to a method for establishing and using a decision marker by which positive samples can be discriminated from negative samples. The method employs the analysis of multiple samples from confirmed positive and negative samples. A fluorescence channel is selected so that the desired sensitivity and specificity are achieved. A microparticle having this fluorescence channel then is made and is used in conjunction with a fluorescence marker which is specific for the population of interest.
