Resource Profile: LabObservationMicrobiologyVirologyObservationvirus - Mappings

Draft as of 2025-06-13

Mappings for the LabObservationMicrobiologyVirologyObservationvirus resource profile.

Scroll down for the Raw FHIR, CDW & SDA mappings (if any).

Note that the CDW, SDA and VPR XML mappings are derived from a look-up based on the VistA source.

   identifierOBX.21 For OBX segments from systems without OBX-21 support a combination of ORC/OBR and OBX must be negotiated between trading partners to uniquely identify the OBX segment. Depending on how V2 has been implemented each of these may be an option: 1) OBR-3 + OBX-3 + OBX-4 or 2) OBR-3 + OBR-4 + OBX-3 + OBX-4 or 2) some other way to uniquely ID the OBR/ORC + OBX-3 + OBX-4.
