After rereading this post and searching further I may be able to add more detail to my question. Earlier on Kathy Mercer said this:
MCnc means that the units should mg/dL (or similar variant)
SCnc means that the units should be mmol/L (or similar variant)
What is meant by the phrase “similar variant”? If a lab test is coded with a LOINC Code that has a property of “SCnc” is that value always going to be in mmol/L units? If it wont always be mmol/L units how do I find out what units the value is in?
If I have a lab test with a result of 100 and it’s LOINC Code is 14770-2 what is the unit type of the measurement? I know based on the property that it’s a substance measurement which means it will be a measurement of moles or milliequivalents but in what ratio? The documentation says that Substance denotes that the observation was reported with moles or milliequivalents in the numerator but it doesn’t tell me where to find what value to put in the denominator, which is 50% of the information I need.
I’m still trying to resolve a LOINC Code to a Unit type (MCnc => mg/dL) for every data type that I’m collecting. This should be the simplest task that should be documented somewhere obvious and easy to resolve, however I’m on week 3 of this problem. Very simply, without using REMLA take me through how I get from 14770-2 —-> to a unit type like mg/dl OR mmol/L
Thanks Kathy! That answers most all of my questions but it does generate one new one. For the Property values is there a place where those are enumerated or described or is it an industry standard or something that I can look up? I’m going to have to try and resolve the Property value to a Unit type (MCnc => mg/dL) for every data type that I’m collecting so that’s why I’m looking for a way to link these two data points.
