I am looking at trying to get a list of orderable tests to a mobile app through a FHIR server. I am looking at the ValueSet resource to provide the list of codes. Orderable tests may include both pathology and radiology items and these can be provided by different providers within the sets. We may be able to order both from a S&N as well as QML, or other pathology provider. My initial thought was to use LOINC for the path codes, but not sure given that I want both path and rad in the same value set.
When I make the request from the FHIR server for the test codes, how should I be searching for them - should I get the FHIR server to create a list based upon a specific name? and then use name as the search parameter?
