*able* to be initiated, yes

I think that in Germany the clinician or helper would input


based on bar coded labels provided by the path lab... I do not know how truly 
Germany achieves for these to be unique.

agree, maybe

        default = auto-incrementing value

configurable (maybe gm-[incrementing value]) so as be compatible with 
externally-dictated values as might have to be manually entered e.g. in German 
bar codes?

provision for such a value (as the praxis might take on, administratively, 
within its local health region) could be a good idea

... but bear in mind ORC 004 has only a length of 20! :-)

no, and would anyway raise the problem you mention below
