## Resource Profile: AU Base Diagnostic Result

Official URL: http://hl7.org.au/fhir/StructureDefinition/au-diagnosticresult | Version: 6.0.0-draft
Standards status: Trial-use | Maturity Level: 1 | Computable Name: AUBaseDiagnosticResult
Copyright/Legal: HL7 Australia© 2018+; Licensed Under Creative Commons No Rights Reserved.

This profile defines an observation structure to represent a diagnostic investigation result issued by a diagnostic service provider in an Australian context. This profile may be used to represent a specialist or other diagnostic (not imaging or pathology) observation including results of audiology studies, sleep studies or speech pathology. The observation may represent the result of a simple investigation or it may group the set of results of a multi-modality procedure or multi-test study / panel.

### Usage Notes

Profile specific implementation guidance:

- The BodyStructure Reference extension may be suitable for use where
  - body site is not implicit in the code found in `Observation.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 `Observation.bodySite`.
- See the AU Base Pathology Result profile for guidance on representing the result of a pathology test.
- See the AU Base Diagnostic Imaging Result profile for guidance on representing the result of a radiology examination or an imaging intensive diagnostic investigation.

Usages:

- Refer to this Profile: AU Base DiagnosticReport, AU Base Diagnostic Result, AU Base Diagnostic Imaging Report, AU Base Diagnostic Imaging Result... Show 2 more, AU Base Pathology Report and AU Base Pathology Result

Changes since version 5.0.0:

- The data elements list has changed
