## EHDS Laboratory Report Mapping

EHDSLaboratoryReport -> Bundle, Composition, DiagnosticReport, ServiceRequest
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.

### EHDSLaboratoryReport -> Bundle, Composition, DiagnosticReport, ServiceRequest

This page explains how conceptual elements from the EHDSLaboratoryReport logical model are expressed in the corresponding FHIR document profiles used by this Implementation Guide. It follows the same mapping style used in the patient summary mapping pages.

Mapping Context

- Source logical model: EHDSLaboratoryReport
- Target FHIR profile: BundleLabReportEu
- Target FHIR profile: CompositionLabReportEu
- Target FHIR profile: DiagnosticReportLabEu
- Target FHIR profile: ServiceRequestLabEu

EHDSLaboratoryReport -> Bundle, Composition, DiagnosticReport, ServiceRequest
EHDSLaboratoryReport (Logical Model) | Relationship | Bundle/Composition/DiagnosticReport/ServiceRequest (EU Lab)
--- | --- | ---
Element | Description | Relation | Resource | Element | Description | Notes
header | Laboratory report header. | related-to | Composition | . | Document-level metadata container. |
header.subject | Subject of care for the report. | equivalent | Composition | subject | Who/what the document is about. | Also aligned with DiagnosticReport.subject.
header.identifier | Business identifier of the report. | equivalent | Composition | identifier | Identifier for the composition instance. |
header.identifier | Business identifier of the report. | equivalent | DiagnosticReport | identifier | Identifier(s) for the diagnostic report. |
header.identifier | Business identifier of the report. | equivalent | Bundle | identifier | Identifier of the document bundle. |

header.legalAuthentication | Legal authentication information. | related-to | Composition | attester | Legal authenticator details. |
header.legalAuthentication.legalAuthenticator[x] | Legal authenticator of the report. | related-to | Composition | attester.party | Party taking legal responsibility. | May require attester mode constraints by implementation rules.
header.legalAuthentication.datetime | Date and time of legal authentication. | equivalent | Composition | attester.time | When legal authentication was recorded. |
header.eventType | Categorisation of the event covered by the document (e.g. laboratory study types, imaging study types including modality, etc.).. | related-to | Composition | category | Report Category | The type of event should be event.code, but the description seems to be a report classification.
header.serviceSpecialty | Clinical/laboratory specialty context. | related-to | Composition | category | Document categorization. | Target usage may vary by implementation constraints.
header.custodian | Organization responsible for maintaining the report. | equivalent | Composition | custodian | Custodian organization. |
presentedForm | Rendered document payload of the report. | equivalent | DiagnosticReport | presentedForm | Entire report as issued (e.g. PDF). |
intendedRecipient[x] | Intended recipients of the report. | equivalent | Composition | extension:information-recipient | Recipients of the document. | Uses EU extension on Composition.
body | Laboratory report structured body. | related-to | Composition | section | Structured narrative/data sections of the report. |
body.orderInformation | Order/request context of the report. | related-to | ServiceRequest | . | Requested service represented as ServiceRequestLabEu. | ServiceRequest referred in the DiagnosticReport as basedOn.
body.orderInformation.orderId | Identifier(s) of the order. | equivalent | ServiceRequest | identifier | Business identifier of the request. |
body.orderInformation.orderDateAndTime | Date/time of order placement. | equivalent | ServiceRequest | authoredOn | When the request was authored. |
