If progress is uncovered, added exams are performed to determine the contaminant, as well as testing problems are reviewed to rule out mistakes.

Time for you to Benefits (TTR): Measures time required to detect microbial advancement and ensures the swift method minimizes overall testing time compared to compendial methods.
