description: This profile constrains the Observation resource to represent results produced by pathology studies in a patient summary. It is informed by the constraints of the [Observation Results (Pathology) IPS-UV profile](http://hl7.org/fhir/uv/ips/StructureDefinition-Observation-results-pathology-uv-ips.html) to allow for cross-border and cross-jurisdiction sharing of Diagnostic Result information. Notably there is no equivalent Canadian Baseline Profile at the time of this draft.
