European Microbiology Conference 2020

Workshop “Validation of Alternative/Rapid Methods”

on 5 May 2020


In this year’s workshop, different approaches for the validation of alternative microbiological methods will be presented on the basis of case studies by microbiologists and statisticians. In particular, the statistical approach will be considered and subsequently the advantages and disadvantages will be discussed. What were the experiences of the scientists, what solutions were pursued and how was the validation carried out?


In a lecture on the European Pharmacopoeia Chapter 5.1.6, the EDQM defined Alternative Methods for Control of Microbiological Quality:
“The aim is to facilitate the implementation and use of alternative microbiological methods (AMM) where this can lead to cost-effective microbiological control and improved assurance for the quality of pharmaceutical products.

Even if the validation of alternative microbiological methods does not always prove to be easy, especially when it comes to demonstrating comparability with existing compendial methods, implementation in QC laboratories is making progress. It has been found that the collection, analysis and evaluation of the data obtained is of great importance for the validation of alternative and rapid methods. Especially if the
results of the alternative methods cannot be presented in the classical cfu, the authority expects “use of statistics to demonstrate equivalency between an alternative and a growth-based compendial method.”

However, there may be different statistical approaches that can be used in the validation process, depending on the method or which microbiological test is affected.
