MPN Panel 4

What is an MPN Test?

The Most Probable Number (MPN) test is a method used to estimate the concentration of viable microorganisms in a sample. This technique is particularly useful in water quality testing and food safety assessments.

How Does the MPN Test Work?

The MPN test involves multiple serial dilutions of the sample, which are then incubated to allow microbial growth. The results are compared to statistical tables to estimate the number of organisms present.

Applications of the MPN Test

MPN tests are widely used in various industries. In water testing, they help determine the level of coliform bacteria, which indicates potential contamination. In food safety, the test ensures products are free from harmful microorganisms, ensuring public health and safety.
