## Resource Profile: AU PS Pathology Result Observation

This profile sets minimum expectations for an Observation resource that represents a pathology result associated with a patient in the context of a patient summary in an Australian context. It is based on the AU Core Pathology Result Observation profile, and applies the additional requirements from Observation Results - Laboratory/Pathology (IPS).

See Comparison With Other National and International IGs for a comparison between AU Patient Summary (AU PS) profiles and profiles in other implementation guides.

### Profile Specific Implementation Guidance

- See the guidance on implementing the pathology result Observation resource in AU Core.
- When implementing support for specimen information, the conformance expectations of the Specimen (IPS) profile SHALL be met.

1. The additional obligation on `Observation.effectiveDateTime` for AU PS Producer is SHOULD:able-to-populate. This obligation is in addition to the obligation of SHALL:populate-if-known. There is no additional obligation for AU PS Consumer, the obligations of SHALL:handle and SHOULD:display apply. This additional obligation is present in the underlying structure but due to a tooling limitation is not currently rendered in the profile view. See Zulip discussion for more information.

2. There is a current tool limitation that prevents the Observation.specimen element referencing the intended target profile: Specimen (IPS).

Examples for this Profile: Bundle/aups-gpvisit-retrieval and Bundle/aups-referral-endoconsult-autogen

Usages:

- Use this Profile: AU PS Bundle
- Refer to this Profile: AU PS Composition and AU PS Pathology Result Observation
