The Biological Indicator Population Verification test determines the number of spores on a biological indicator (BI) and is typically used to confirm the BI manufacturer’s stated value is representative of the batch. Furthermore, Biological indicators can provide a worst-case plot sterilization method by applying an organism that is resistant to a sterilant used in the specific application. This test can also be used to find out survivors from a sterilization process and calculate lethality rates and D-values. https://www.ste-mart.com/b...
