This profile constrains the US Core Laboratory Result Observation to At-Home In-Vitro Sample Tests.
This is a framework profile and can be the base of another profile that is further constrained to meet the requirements of a specific use case. See Observation - At-Home In-Vitro Test Result - COVID-19 for an example of such a profile.
The following elements are expected to be constrained to use case specific value sets:
