The purpose of the guide is to help laboratories engaged in routine microbiological analysis to calculate uncertainties of their test results. Only test based on counting colonies or other discrete entities are considered. In everyday speech "uncertainty" has wide connotations, even in the context of analytical measurements. In this treatise, measurement uncertainty is considered. Other uncertainties, such as the uncertainty of identifying the object of measurement (the target organism), are not considered. With the help of this guide, it should be possible to obtain a numerical estimate of uncertainty for each individual test result. Also, advise is given on the estimation of major systematic errors.
