3.5.1 Animal and non-animal method and assay qualification

From EQIPD
Jump to: navigation, search

​​​​A. Background & Definitions

Research methods utilized must be demonstrated to be 'fit for purpose'.


B. Guidance & Expectations

Prior to use:

  • There must be a procedure for the qualification of research methods as 'fit for purpose'. This includes non-standard methods and laboratory-developed methods.
  • Any modifications of qualified research methods or use outside their intended scope should be made transparant and additional qualification should be conducted as needed.
  • Records of the qualification should be retained (incl. used validation procedure, specification of requirements, results obtained, statement of the fitness for intended use).

During use:

  • Method robustness should be monitored, through variation of controlled parameters, comparison of results achieved with other validated methods and/or interlaboratory comparison.
  • Users performing assays must be qualified, trained and have access to written instructions on the assay.
  • The qualified method used as well as any deviations from the qualified method must be documented in the experimental record with impact asessment.
  • It may be helpfull to have a repository of methods and assays with version control so that the method and version used can be referenced in the study data.
