What is the Difference Between Reporting Microbiology Testing per CFU or MPN?
Video Overview
The difference between reporting as CFU or MPN per unit of measure is due to their respective methods. CFUs or "colony forming units" are determined by directly counting visible colonies of bacterial growth on the plate or film. MPN, or Most Probable Number, on the other hand measures growth statistically. In this method, sample is added to a series of test tubes with special media at different concentrations. The MPN value is then measured based on the reaction levels in the tubes and the value is then calculated with a 95% confidence interval.
