This profile sets minimum expectations for a ServiceRequest resource that is used to record, search, and fetch information about diagnostic requests for a patient. It is based on the[AU Base ServiceRequest](https://build.fhir.org/ig/hl7au/au-fhir-base/StructureDefinition-au-servicerequest.html)profile and identifies the additional constraints, extensions, vocabularies and value sets that**SHALL**be present in the ServiceRequest resource when conforming to this profile. 

### Profile Specific Implementation Guidance

* This abstract profile provides a shared base that is common across requests for specific domains. It is not intended for direct implementation. Where a profile is defined for a specific domain that profile **SHALL** be used: 
* Pathology requests **SHALL** use [AU eRequesting Pathology Request](StructureDefinition-au-erequesting-servicerequest-path.md) profile
* Imaging requests **SHALL** use [AU eRequesting Imaging Request](StructureDefinition-au-erequesting-servicerequest-imag.md) profile
 
* This profile supports the sex and gender related concept of Sex Parameter for Clinical Use: 
* When exchanging concepts of sex or gender, refer to the guidance in [Sex and Gender](sex-and-gender.md) and the [Gender Harmony Implementation Guide](http://hl7.org/xprod/ig/uv/gender-harmony/).
 
* See guidance on the construction of identifiers in each Identifier profile and the section on [Business Identifiers](https://build.fhir.org/ig/hl7au/au-fhir-base/generalguidance.html#business-identifiers) in AU Base.
* Refer to the [AU eRequesting Workflow Guidance](workflow.md) page for guidance on managing workflow states in AU eRequesting.
* See the [Diagnostic Request Grouping](general-guidance.md#diagnostic-request-grouping) section for guidance on grouping diagnostic requests in AU eRequesting.
* The provision of an insurance attribute describes a recommendation to be considered by the filler and does not guarantee that this recommendation will be satisfied.
* `ServiceRequest.encounter` and `ServiceRequest.encounter.reference` are mandatory to support `Encounter.class`, which classifies the patient encounter and is required by the filler for billing purposes.
* `ServiceRequest.occurenceTiming.repeat.count` can be used to specify the number of diagnostic requests to be performed.
* Resources referenced by `ServiceRequest.supportingInfo` can be referenced by all ServiceRequests in a group when the information applies across the group, or by individual ServiceRequests when the information is specific to particular requests. 
* Use `ServiceRequest.supportingInfo:pregnancyStatus` to record pregnancy, with the permitted value of Pregnant, only when it applies to the request.
* Use `ServiceRequest.supportingInfo:clinicalContext` to supply text narrative that provides the broader clinical background or circumstances related to the request.
 
* Use `ServiceRequest.note` to record general comments or administrative notes about the request. 
* Information recorded in `ServiceRequest.note` **SHALL NOT** duplicate or overlap with clinical context captured in `ServiceRequest.supportingInfo:clinicalContext`, or with any other information recorded in the ServiceRequest.
 

**Usages:**

* Derived from this Profile: [AU eRequesting Imaging Request](StructureDefinition-au-erequesting-servicerequest-imag.md) and [AU eRequesting Pathology Request](StructureDefinition-au-erequesting-servicerequest-path.md)

* The resource metadata has changed (description)

* The data elements list has changed

* One or more text definitions, invariants or bindings have changed

### Notes:

Below is an overview of the mandatory and optional search parameters and combined search parameters. See the [AU eRequesting CapabilityStatements](capability-statements.md) for a complete list of supported RESTful interactions for this IG.

FHIR search operations are described [here](http://hl7.org/fhir/R4/search.html) and the syntax used to describe AU eRequesting interactions is defined [here](https://build.fhir.org/ig/hl7au/au-fhir-core/general-guidance.html#readsearch-syntax).

Any search parameter defined in FHIR may be 'allowed' by the system unless explicitly marked as "**SHALL NOT**".

#### Search Parameters:

The following search parameters and search parameter combinations are supported. Conformance obligations are detailed in the table above.

1. **[`_id`](https://hl7.org/fhir/R4/servicerequest.html#search)**search parameter
* including support for these **[`_include`](http://hl7.org/fhir/R4/search.html#include)** parameters: `ServiceRequest:patient`, `ServiceRequest:requester`, `ServiceRequest:encounter`, `ServiceRequest:supporting-info`
`GET [base]/ServiceRequest?_id=[id]`Example:

1. GET [base]/ServiceRequest?_id=2169591&_include=ServiceRequest:patient&_include=ServiceRequest:requester&_include=ServiceRequest:encounter&_include=ServiceRequest:supporting-info
**Implementation Notes:**Fetches a bundle with the requested ServiceRequest, instead of just the resource itself, and allows for the inclusion of additional search parameters such as _include, _revinclude, or _lastUpdated ([how to search by id of the resource](https://hl7.org/fhir/r4/search.html#id))
1. **[`requisition`](https://hl7.org/fhir/R4/servicerequest.html#search)**search parameter

1. GET [base]/ServiceRequest?requisition=EMC4542244-5624&_include=ServiceRequest:patient&_include=ServiceRequest:requester&_include=ServiceRequest:encounter&_include=ServiceRequest:supporting-info
**Implementation Notes:**Fetches a bundle of all ServiceRequest resources for the specified requisition identifier ([how to search by token](https://hl7.org/fhir/R4/search.html#token))
