This profile defines a service request structure to represent a request for a diagnostic investigation in an Australian context. This profile is intended to support ordering for pathology, radiology, and specialist diagnostic investigations. 

This profile is deprecated in AU Base as work is being undertaken in the [AU eRequesting](https://build.fhir.org/ig/hl7au/au-fhir-erequesting) project to define the requirements for a diagnostic request. In AU Base this profile is replaced by [AU Base ServiceRequest](StructureDefinition-au-servicerequest.md), which localises core concepts, including identifiers and terminology, for use in an Australian context and enables implementers and modellers to make their own rules, i.e. ([profiling](http://hl7.org/fhir/profiling.html)), about how to support these concepts for specific implementation needs.

### Usage Notes

**Profile specific implementation guidance:**

* The [procedure-targetBodyStructure](http://hl7.org/fhir/R4/extension-procedure-targetbodystructure.html) extension may be suitable for use where 
* body site is not implicit in the code found in `ServiceRequest.code` and
* body site information is to be handled as a separate resource (e.g. to identify and track separately) instead of an inline coded element in `ServiceRequest.bodySite`.
 
* `ServiceRequest.code` for a pathology order is preferred to be a member of the [RCPA - SPIA Requesting Pathology Terminology Reference Set](https://www.healthterminologies.gov.au/integration/R4/fhir/ValueSet/spia-requesting-refset-3).
* `ServiceRequest.code` for an imaging order is preferred to be a member of the [Imaging Procedure](https://healthterminologies.gov.au/fhir/ValueSet/imaging-procedure-1) value set.
* See each Identifier profile page for guidance related to that identifier type.

**Extensions under consideration:**

* ServiceRequest: [Result Copies To](StructureDefinition-result-copies-to.md)

**Usages:**

* This Profile is not used by any profiles in this Implementation Guide

**Changes since version 5.0.0:**

* The data elements list has changed

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