Ah yes, that's definitely not right. There are actually two blood glucose archetypes, and the other one has 'IU' (which should be [iU]).
Probably all of the current OBSERVATION.lab_test* and OBSERVATION.pathology_test* archetypes should be deprecated and (some of them) redone as either cluster extensions or specialisations of the newer OBSERVATION.laboratory_test archetype. I think it would be very useful if you would be willing to proof read my Archetype Editor units file if we can ever get it into a form that the AE will accept. :) Regards, Silje -----Original Message----- From: openEHR-technical [mailto:openehr-technical-boun...@lists.openehr.org] On Behalf Of Eric Browne Sent: Wednesday, May 18, 2016 4:30 PM To: For openEHR technical discussions <openehr-technical@lists.openehr.org> Subject: Re: UCUM code in body temperature archetype Hi Silje, 'U' is used in the lab_test-blood_glucose archetype. I also think that 10*12/l, 10*6/l, 10*6/mm3, 10*9/l are all valid UCUM codes. In fact UCUM's table 26 Example Unit Terms by Term lists 10*6/mm3 as legal with a preferred alternative of /pL . It also lists the following alternatives:- 10*3/L = /mL 10*6/L = /uL 10*9/L = /nL with all 6 codes being valid. regards, eric > On 18 May 2016, at 11:43 pm, Bakke, Silje Ljosland > <silje.ljosland.ba...@nasjonalikt.no> wrote: > > Hah, thanks for that correction, I completely missed the '0' instead > of 'O' and the 'mho'.
