AU Base Implementation Guide
6.0.1-ci-build - CI Build

AU Base Implementation Guide, published by HL7 Australia. This guide is not an authorized publication; it is the continuous build for version 6.0.1-ci-build built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/AuDigitalHealth/au-fhir-base/ and changes regularly. See the Directory of published versions

## Resource Profile: AU Base Pathology Result

Official URL: http://hl7.org.au/fhir/StructureDefinition/au-pathologyresult | Version: 6.0.1-ci-build
Standards status: Trial-use | Maturity Level: 1 | Computable Name: AUBasePathologyResult
Copyright/Legal: HL7 Australia© 2018+; Licensed Under Creative Commons No Rights Reserved.

This profile defines an observation structure to represent a pathology test result issued by a diagnostic service provider in an Australian context. This profile is intended to be capable of supporting reporting for all pathology disciplines (e.g. including microbiology, histopathology, cytology, blood transfusion) with the exception of genomics. The observation may represent the result of a simple test such as haemoglobin or it may group the set of results produced by a multi-test study or panel such as a full blood count, or urine specimen study.

This profile does not provide full support for structured pathology reporting. It is expected that this support is best handled by a set of profiles that represent the structured reporting requirements for each specific protocol (see for example RCPA’s structured pathology reporting of cancer); this is not in the scope of this implementation guide at this time.

### Usage Notes

Profile specific implementation guidance:

- When sending an observation that represents a study series or panel:
  - the group / panel code is sent in `Observation.code`
  - the overall comments are sent in `Observation.note`
  - the global interpretation by the producer of the study is sent in `Observation.interpretation`
  - individual results may be sent in `Observation.component` or by referencing individual observation results in `Observation.hasMember`
- When sending a discipline specific laboratory result, one of discipline specific value sets may be more suitable for use than the entire reporting value set bound in this profile to `Observation.code`:
  - ValueSet : RCPA - SPIA Chemical Pathology Terminology Reference Set
  - ValueSet : RCPA - SPIA Haematology Terminology Reference Set
  - ValueSet : RCPA - SPIA Immunopathology Terminology Reference Set
  - ValueSet : RCPA - SPIA Microbiology Serology Molecular Pathology Terminology Reference Set
- This profile supports the sex, gender, and related concept of Sex Parameter for Clinical Use:
  - When exchanging concepts of sex or gender, refer to the guidance in Sex and Gender and the Gender Harmony Implementation Guide.

Usages:

- Refer to this Profile: AU Base DiagnosticReport, AU Base Diagnostic Result, AU Base Pathology Report and AU Base Pathology Result
- Examples for this Profile: Observation/specimen-hepatitis-b-serology
