Profiles -The current focus of implementing -The current focus of implementing USLabOrder is using a FHIR Bundle Resource to exchange a DiagnosticOrder Profile and the Resource Profiles it references. This FHIR bundle completely defines the laboratory order. The Resource Profiles that may be used in the bundle are outlined below: (This list is not meant to be exhaustive as additional resources may also to be used) US Lab DiagnosticOrder constrains and extends is using a FHIR Bundle Resource to exchange a DiagnosticOrder Profile and the Resource Profiles it references.
