## EHDS ServiceRequest Mapping

# EHDSServiceRequest -> ServiceRequestLabEu

**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.

### EHDSServiceRequest -> ServiceRequestLabEu

 This page explains how conceptual elements from the EHDS Service Request logical model are expressed in the corresponding FHIR ServiceRequest profile used by this Implementation Guide. 

**Mapping Context**
*  **Source logical model:** [ EHDSServiceRequest ](https://www.xt-ehr.eu/fhir/models/0.3.0/StructureDefinition-EHDSServiceRequest.html) 
*  **Target FHIR profile:** [ServiceRequestLabEu](StructureDefinition-ServiceRequest-eu-lab.md)

| Element | Description | Relation | Resource | Element | Description | Notes |
| header | Common header inherited from EHDSDataSet. | related-to | ServiceRequest | . | General metadata container. |  |
| header.subject | Patient/subject of care. | equivalent | ServiceRequest | subject | Who or what the request is about. |  |
| header.identifier | Business identifier. | equivalent | ServiceRequest | identifier | Placer/filler order identifiers. |  |
| header.author[x] | Author of the resource. | related-to | ServiceRequest | requester | Requester of the service. | Closest fit; semantic alignment may vary by workflow. |
| header.date | Date and time of authoring. | equivalent | ServiceRequest | authoredOn | Date request was created. |  |
| header.status | Status of the request. | equivalent | ServiceRequest | status | Request lifecycle state. |  |
| header.language | Language of the resource. | equivalent | ServiceRequest | language | Language of content/narrative. |  |
| description | Textual description of the requested service. | related-to | ServiceRequest | text |  |  |
| code | Code and name identifying requested service. | equivalent | ServiceRequest | code | What is being requested. |  |
| quantity | Amount of requested services of same type. | related-to | ServiceRequest | quantity[x] | Requested quantity. | Typically Quantity in laboratory use cases. |
| bodySite | Anatomic location/laterality of requested procedure. | related-to | ServiceRequest | bodySite | Target site |  |
| reason[x] | Reason why service is requested. | equivalent | ServiceRequest | reasonCode | Clinical justification. | If reason is a coded value, it maps to reasonCode. |
| reason[x] | Reason why service is requested. | equivalent | ServiceRequest | reasonReference | Clinical justification. | Reason details are represented as references to other resources. |

| specimen | Specimen(s) to be used for laboratory procedure. | equivalent | ServiceRequest | specimen | Referenced specimen resources. |  |
| encounter | Encounter context of the request. | equivalent | ServiceRequest | encounter | Healthcare context of request. |  |
| occurrence[x] | Expected time of the service. | equivalent | ServiceRequest | occurrence[x] | Requested occurrence timing. |  |
| patientInstructions | Patient or consumer-oriented instructions. | equivalent | ServiceRequest | patientInstruction | Instructions to patient/subject. |  |
