Experienced antimicrobial product developers know that test-to-test variability can be a real challenge. When results vary from one study to the next, one is left wondering, “Is the difference a result of ordinary variability or is it evidence of a procedural change between tests?”


Antimicrobial Test Labs helps by working hard to identify and reduce sources of variability. For instance, we train our microbiologists extensively to achieve consistent performance and run several controls with each study.  Our customers in turn help us by learning not to oversimplify causal relationships within complex microbiological systems, by anticipating ordinary variability in studies.  Dr. Grosse-Siestup gave this topic excellent consideration in this new article on variability in antimicrobial testing. We hope it will help those who read it to more effectively navigate antimicrobial product development.
