PATH-R4-30: UKCore-Observation (Test Result) Snippets

An example of how each key UKCore-Observation-Lab data element may be populated to represent a test result is provided below. Please note that the examples are provided to illustrate individual data element usage; the full set of data elements may not necessarily be consistent with one another or illustrate a single, complete clinical scenario.

Refer to the UKCore-Observation-Lab profile definition for a detailed description of the supported data elements.
