This page describes patient's use cases for the retrieval of laboratory results, in a personal health environment (PHR) context. Functional specifications are described at the [[MedMij:V2020.01/Ontwerpen| functional design wiki page]]. The technical specification is described here. HL7 FHIR STU3 is used for this purpose.

'''Note''': This implementation guide builds on the general guidelines described in the [[MedMij:V2020.01/FHIR_IG#Use case overarching principles|use case overarching principles]].

Many laboratory result observations have important relationships to other observations and need to be grouped together. [http://hl7.org/fhir/observation.html#10.1.4.1 The FHIR specification] defines three structures to do this: DiagnosticReport and DiagnosticReport.result, Observation and Observation.component, and Observation and Observation.related. For the transactions of laboratory results retrieval, the following two grouping structures are relevant. 

====Observation====
Individual laboratory results are represented by Observation resources, such as one blood glucose value. The Observation resource can also be used as a structure for a panel or battery observation. Observation.related is used for any supporting result that can be interpreted and used on its own and has one or more different values for method, observation, performer, device, time, and/or error conditions. The top-level observation specifies the grouping code in Observation.code, but typically does not have its own Observation.value, and the set of member observations are listed in the Observation.related element.

====DiagnosticReport====
In contrast to the Observation resource, the DiagnosticReport resource typically includes additional clinical context and some mix of atomic results, images, imaging reports, textual and coded interpretation, and formatted representations. Report conclusions can be expressed as a simple text blob, structured coded data or as an attached fully formatted report such as a PDF. The DiagnosticReport.code names the panel and serves as the grouping element, which is traditionally referred to as a "panel" or "battery" by laboratories. The DiagnosticReport.result element references the individual observations.

Both structures may exist in a XIS. Therefore, two transactions are defined to retrieve a patient's laboratory results. The transaction content either consists of a single and related laboratory results structure or a complete diagnostic report that adds more clinical meaning to the single and related laboratory results. The transactions:

* [[MedMij:V2020.01/FHIR_LaboratoryResults#Use_case:_retrieve_laboratory_results| Retrieve laboratory results]]
* [[MedMij:V2020.01/FHIR_LaboratoryResults#Use_case:_retrieve_laboratory_results_DiagnosticReport| Retrieve laboratory results DiagnosticReport]]

==Introduction==
The retrieve laboratory results transaction is used by the PHR to retrieve laboratory results from a XIS.

==Invocations==
===PHR: request message===
The request message represents an HTTP GET parameterized query from the PHR to the XIS.

====Trigger Events====
When the patient(PHR) wants to obtain laboratory results, it issues a retrieve laboratory results request message.

====Message Semantics====
The PHR executes an HTTP GET conform to the FHIR [http://hl7.org/fhir/http.html RESTful] and [http://hl7.org/fhir/search.html search] specification against the XIS's Observation endpoint. This search query URL is configurable by the PHR and has the following format:
 
<pre>GET [base]/Observation?category=http://snomed.info/sct|49581000146104{&[parameters]}</pre>

The PHR may use, and the XIS shall be capable of processing, the following parameters to configure the search query:
{| class="wikitable" 
! Name
! Description
! Examples
|-
| [https://www.hl7.org/fhir/stu3/observation.html#search date]
| Obtained date/time for the result. If the result was obtained over a period, this parameter should be interpreted as a date that falls in this period.
| Retrieve all zib LaboratoryTestResults Observation resources that have an effective date greater than 01-01-2010:
<pre>GET [base]/Observation?category=http://snomed.info/sct|49581000146104&date=ge2010-01-01</pre>
Retrieve all zib LaboratoryTestResults Observation resources that have an effective date within a 2 year period:
<pre>GET [base]/Observation?_include=Observation:specimen&category=http://snomed.info/sct|49581000146104date=ge2010-01-01&date=le2011-12-31</pre>

| Retrieve all zib LaboratoryTestResults Observation resources:

|-
| [http://hl7.org/fhir/STU3/search.html#include _include]
| The PHR may request that the XIS returns resources related to the search results, in order to reduce the overall network delay of repeated retrievals of related resources.
| Retrieve all zib LaboratoryTestResults Observation resources and include Specimen information in the search results:
<pre>GET [base]/Observation?_include=Observation:specimen&category=http://snomed.info/sct|49581000146104</pre>
|}

=====Expected Actions=====
The XIS shall process the query to discover Observation resources that match the search parameters given.

===XIS: response message===
The XIS returns an HTTP Status code appropriate to the processing as well as a FHIR Bundle including the matching observation information.

====Trigger Events====
The XIS completed processing of the retrieve laboratory results request message.

====Message Semantics====
The returned data to the PHR should conform to the HCIMs and their associated profiles listed in the table below. The resources in the response message SHALL be a valid instance of these profiles. All resources SHALL include their related profile canonical URL in the ''meta.profile'' element in order to show compliance.
