A Most Probable Number (MPN) water testing kit is a statistical method for estimating the bacterial count in a water sample, particularly useful for detecting coliforms and E. coli in water.
The most probable number technique is a broth culture-based technique that involves replicated dilution of samples in suitable test media. It is a statistical method used to estimate the viable numbers of bacteria in a sample by inoculating broth in 10-fold dilutions, and is based on the principle of extinction dilution. Due to the convenience of the MPN method, it is frequently applicable in water analysis and quality testing and assurance of water and liquid products.
