Unit concept IDs described as "Kelvin per" volume? Possible mistranslation

Greetings all,

First-time user here with an issue with the units for blood cell counts. Concept IDs 8792 and 8903 are named “Kelvin per microliter” and “Kelvin per cubic millimeter”, respectively, which doesn’t seem to correlate with commonly used units in any discipline. Looking into data that is associated with these units, they seem to be attached to blood cell counts, which are sometimes reported in “K per uL” or “K per mm^3”, in which the K refers to thousands rather than Kelvin; the concept codes of these units (K/uL and K/mm3, respectively) seem to bear that out. I searched the boards and couldn’t find an existing thread on this topic; is this the place to raise it?

Thanks,

@FrmrHealthEcon:

Welcome to the family.

8792 and 8903 are invalid concepts. They have an invalid_reason=‘U’, which means they are updated. You can find out what they are replaced by using the CONCEPT_RELATIONSHIP table, and you’ll find out that they point to 8848 “thousand per microliter” and 8961 “thousand per cubic millimeter” (which actually are the same thing, but we haven’t introduced interchangeability, yet). The Kelvin thing was a mistake of somebody introducing standard UCUM units early on. It’s been fixed on the valid_end_date=03-JAN-2014.

Many thanks Christian. We’ve been converting these invalid concepts into the same ones you refer to, so I’m glad to hear we’re on the same page.
