## EHDS Laboratory Observation Mapping

EHDSLaboratoryObservation -> ObservationResultsLaboratoryEu
Ongoing alignment: The Xt-EHR logical models are under active revision and continuous refinement. Updates from Xt-EHR will be progressively incorporated into this Implementation Guide to maintain alignment with the evolving EHDS specifications.
Yellow row/cells: In this ballot publication, some row/cells of the mapping table have been left in yellow to indicate areas requiring further review or refinement; including feedback from the Xt-EHR joint action (see note above). These highlights will be addressed in subsequent updates to ensure accuracy and completeness of the mappings.

### EHDSLaboratoryObservation -> ObservationResultsLaboratoryEu

This page explains how conceptual elements from the EHDS logical model are expressed in the corresponding FHIR Observation profile or type used by this Implementation Guide.

Mapping Context

- Source logical model: EHDSLaboratoryObservation
- Target FHIR profile: ObservationResultsLaboratoryEu
