Map to which FHIR resource for Lab Performer?

1

Should Lab Performer be mapped to resource Practitioner or resource Organization?
If mapped to resource Practitioner, there is no property to capture the health organization which the Lab Performer is associated with. Please advise, thanks.

If you just want the Lab, use Organization. If you want the lab + the technician, use PractitionerRole, which can then point to both Organization and Practitioner. If you’re using STU3, you’ll have to use an extension as PractitionerRole isn’t one of the allowed resources
