Request to add new Unit Concept

Hi! I need to use the unit ‘RU/ml’ and I couldn’t find it anywhere. Is it possible to create it in a new concept_id? Thanks!

Hello, Marcos!

RU/ml is basically equivalent to U/ml normalized to the specific diagnostic test, isn’t it?
In other words, RU/ml can be converted to U/ml using a coefficient specific to the diagnostic assay.

Hi! Thanks for your answer.
I’m not sure about converting RU/ml to U/ml. RU/ml refers to the relative amount of reaction measured in the context of a specific assay, and is normally used if no international standard references exist for the conversion.

I have found several lab tests with this unit and it would be great to directly assign the corresponding concept to it. I don’t see the point of assigning another unit to it and then having to convert it back (if possible) to the original unit.

Hello, Marcos!

Thank you for the clarification.
We will include this new UCUM concept in the upcoming Winter release.

Regards,
Masha
