Validation of Microbial Recovery – Method Suitability Studies

Webinar to be presented Thursday, September 20 at 2 pm EST


Microbiological assays require recovery and growth of microorganisms. While the Sterility Tests and the Microbial Limit Tests have the “validation” or “method suitability” studies are part of the procedure, many tests do not. USP Chapter <1227> was designed to provide information on the design of these studies, and to provide information on the limitations of the plate count method. This webinar will review USP <1227> with emphasis on how it can be used to strengthen all assays in the QC microbiology laboratory.
