Dear Joe, Method validations, equipment/instruments/facilities qualification(s), written sound procedures, data integrity and traceability are not an exclusive of GxP lab’s but it is mandatory to ensure that all these requirements are enforced whereas non-compliant GxP lab’s may not fulfil all of them. As such, how do you plan to compare data generated in such potentially different environments. Kind regards, Luis

don't know.  First I'd want to see the data, and then see what makes sense....  however, since I haven't seen anything... no worries

thanks for replying,

best regards,

joe
