As an example, if a product is formulated and filtered just before a final sterilization, microbiological testing with the Bio-load just after filtration will deliver some handy details for that determination of the adequacy of the sterilization approach. Having said that, it's going to offer small, if any, information and facts pertaining into the adequacy of the method with respect to reducing endotoxin contamination. Considering the fact that endotoxins result from large amounts of microorganisms, and so are not taken out by sterilizing or microbiological filters, the subsequent reduction of the significant microbiological level will not be linked to a similar reduction of high endotoxin stage.
