How is MPN calculated? The MPN Table (Table 4) is based on 3 dilutions of decreasing decimal increments. Example: Five tubes of undiluted sample, 5 tubes of 10X dilution, and 5 tubes of 100X dilution are inoculated initially. Positive results are obtained from 5 of the undiluted samples, 5 of the 10X dilutions, and 3 of the 100X dilutions.The subclause relating to enumeration using liquid media had been expanded and includes additional guidance on the use of MPN calculators.
