Evaluation and decision
For each validation study, there are three presentations to the technical committee:
- draft preliminary study,
- results of preliminary study,
- results of inter-laboratory study.
At each stage, the expert laboratory in charge of the study presents the application with the manufacturer present. The technical board evaluates the application and decides on whether to validate the method at the stage of the results of the inter-laboratory study .
The technical board consists of twenty or so microbiology experts, some of whom have expertise in statistics. These members represent all the interests at stake in validation: the users of the methods, kit manufacturers and the technical organisations and authorities that use the analytical results.
Two members of the technical board (the reviewers) are appointed to report in detail on each study and liaise with the expert laboratory. Their opinion is given priority during the presentation of results.
After the technical board has finally approved the validation, and the contents of the technical instructions for the validated method, AFNOR Certification issues the NF VALIDATION mark. A certificate is drafted which includes general information on the method as well as a summary of the tests and the main results obtained.
The certificate, as well as the NF VALIDATION mark shown on commercial documents and advertising material, is a guarantee of the effectiveness of the method validated.
