Topic: How to encoding double datatype Observation?

There are some lab results that have two datatype: valueString ("Negative" or "(-)") if it's negative and valueQuantity if it has positive quantity (2.5mmol/L). Thanks.

It's pretty common in some lab panels such as urine analysis.
Lin Zhang (Dec 02 2020 at 14:55):
And whether it has a quantitative value, there is always a quantitative reference range along with it.
Lloyd McKenzie (Dec 02 2020 at 15:21):
In FHIR, the 'negative' would go in Observation.interpretation
Lin Zhang (Dec 02 2020 at 23:18):
Good idea. And so we would need arbituarily create a value (0 or <= low limit of the reference range?) for the valueQuantity.
Lloyd McKenzie (Dec 03 2020 at 00:23):
You don't have to have a value
Lin Zhang (Dec 03 2020 at 03:59):
Got it. Thanks, Lloyd:blush:
