New: Is Your Primary Device Count Greater Than One?
Assign the "Unit of Use" Packaging Level

GS1 US Data Hub now provides a “Unit of Use” packaging level. The Unit of Use DI is defined as an identifier assigned to an individual medical device when the Primary DI has a "count of devices" greater than 1.

The Unit of Use DI is assigned to the single device below the lowest saleable unit marked with a DI. This allows for unique identification of the actual device used in patient care.
