The current growth-based Sterility Tests with at least 14-days incubation is not suitable for short-lived products. An expert panel was formed under the USP General Chapters– Microbiology Expert Committee to provide recommendations on user requirements specifications and candidate technologies based on the URS in the area of rapid sterility tests. Based on the evaluation of the URS, the expert panel made recommendations for appropriate modern/rapid technologies available from multiple vendors. The next step would be to recruit collaborating labs to conduct the proof-of-concept studies that would support drafting of a rapid sterility test chapter in the USP.
