Hi,

I hope this answer help you to get a more precise one.

First of all you must make a choice.

Alternative 1: use the simpliest code possible, assuring one precise and robust identification, and nothing more. It means, that you put in the code only an identification non repetable, may be hashed to avoid alteration, and you relay on your cental system (LIMS) to have all the other informations regarding the process. Disavantage, as all the complementary information is in the LIMS you need continuously access to it,.

Alternative 2:   you can add complementary information to the code, as instructions, agent, history of process, pickup place, stage, etc. In this case, the sample is more autonomous, as it travels with a lot of information and instructions to take care of it, it means it carry its situation. As disadvantage, you must update the labels at every new stage, but can work with the sample even without LIMS, or in between diferents systems.

Recommendation, use the sampliest code possible, let all the other info in the LIMS, but add some little redundant information for simplification process, Informations HTA doesn’t change during the proses, for instance: date, hour and sampling’s point, material.
