AOAC International has implemented a new pathway for recognizing methods as official methods of analysis. This interactive
pathway integrates the development of defined method performance requirements with an expanded role of an assigned
expert review panel (ERP). This presentation will review the process including the new tools being used to assess a method?s
The pathway begins with a panel of stakeholders defining an analytical method?s requirements so that analytical results
address current needs. An ERP is then created and assigned to review candidate methods against those requirements. Methods
can then be recognized as official first action if acceptable. The ERP then monitors the method?s real-world performance during
a two year period. During this evaluation period, the ERP collects information on the method?s reproducibility, its performance
in a working environment, identifies any safety concerns, and also other in-use factors. The mechanisms to evaluate the method?s
performance are flexible and allow for new approaches to determine a method?s reproducibility and practical performance needs.
Methods recommended for final action status by the ERP are sent to the AOAC official methods board for final review.
