HL7 Version 2 to FHIR
1.0.0-ballot - ballot International flag

HL7 Version 2 to FHIR, published by HL7 International / Orders and Observations. This guide is not an authorized publication; it is the continuous build for version 1.0.0-ballot built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/HL7/v2-to-fhir/ and changes regularly. See the Directory of published versions

That is not known at the standard level, so we cannot provide specific mapping guidance here.  However, if the mapper does not have access to the syntax used and its meaning, we need to be able to pass on OBX-4 Sub Identifier to the final destination that should know how to then structure it using FHIR attributes."

To enable relating the calculated observation to the correct specimens it relates to, the v2 message should include the originating observations that in turn use OBX-33 to link to the correct specimens.  Without that, and if there are multiple specimens in OBX-33, there is no standard method to correctly associate the observation with the correct specimens.  The implementer will have to devise an appropriate method for that in their context."
