GUIDELINES ON VALIDATION – APPENDIX 4
3 ANALYTICAL METHOD VALIDATION
4 (June 2016)
5 DRAFT FOR COMMENTS
8. METHOD TRANSFER
293
294 8.1 During method transfer, documented evidence should be established to prove that a
295 method has equivalent performance when used in a laboratory different from that where it has
296 been originally validated.
297
298 8.2 Generally, it should be performed by comparing a set of results obtained by an analyst in
299 one laboratory to that obtained by another analyst at the laboratory to which the method is being
300 transferred.
301
302 8.3 The two sets of results should be statistically compared and the differences between the
303 two sets of test results should be within an acceptable range.
304
305 8.4 Method transfer should be performed before testing of samples for obtaining critical data
306 for a dossier, such as process validation or stability studies or applied for routine use.
307
308 8.5 A predefined protocol should be followed which includes at least: a title, objective,
309 scope, responsibilities of the sending unit (SU) and the receiving unit (RU); a specification of
310 materials and methods; the experimental design and acceptance criteria; documentation
311 (including information to be supplied with the results, and report forms to be used, if any);
312 procedure for the handling of deviations; references; and details of reference samples (starting
313 materials, intermediates and finished products). The protocol should be authorized and dated.
314
315 8.6 In the case of independent testing by a separate entity, such as a national quality control
316 testing laboratory that is testing samples on its market, method transfer is not always possible. It
317 is not considered an obligation but may be considered as an optional step when encountering
318 difficulties in applying any particular method. See WHO guidelines on transfer of technology in
319 pharmaceutical technology (3) for further reference.
