Over the next two weeks I have a very special treat for RxTrace readers.  It is an interview with Ken Traub, GS1 standards expert and independent consultant.  The subject is GS1 serial number randomization, something so important that I think pharma companies ought to give deep thought to it before they turn on their serial number applications.

Pharma manufacturer who sell into the E.U. and/or Brazil markets will be forced to randomize their serial numbers because of regulatory requirements, but even those who only sell into the U.S. market should strongly consider randomization.  I’ll have more to say about why in a follow-up essay after this series is over.

Because the interview with Ken covers the topic so thoroughly, it is long.  That’s good, because it provides readers with an easy to understand explanation of everything they need to know about randomizing.  But it also makes for a very long essay, so I have broken the interview down into five RxTrace essays.  Read sequentially, they contain the complete interview.  The subtopics covered by those essays include: Continue reading Randomization—An Interview with Ken Traub—Part 1: GS1 Serial Number Considerations
