Transfer of analytical methods

 Chris Smith (MHRA) has written the MHRA’s thoughts on the transfer of analytical methods.


Common inspection deficiencies for analytical method transfer listed by MHRA are:


·         Equipment was not qualified for the range used in the transferred method.

·         The impact of differences in equipment was not included in the gap analysis - such as different makes and models of high performance liquid chromatography (HPLC) equipment used at transferring and receiving sites.

·         The receiving laboratory did not follow the transfer protocol.

·         The method references internal documents from the transferring laboratory which were not available at the receiving laboratory.

·         AMT was performed as a single test, on one batch of product: examples being, one single agar plate for a microbiology assay, one dissolution test, one assay test without appropriate justification.


·         A single strength was used to transfer methods used for multiple strengths.
