description: Provides guidance as to which `DiagnosticReport` attributes should be present and considerations as to how each attribute should be valued in [`DiagnosticReport-select`](3-6-4-DiagnosticReport-select.html) events.\n\nThe `DiagnosticReport` in [`DiagnosticReport-select`](3-6-4-DiagnosticReport-select.html) events enables verification that the selected content in the [`DiagnosticReport-select`](3-6-4-DiagnosticReport-select.html) event belongs to the DiagnosticReport which is the current anchor context.\n\nHence, the only required attributes of `DiagnosticReport` in the [`DiagnosticReport-select`](3-6-4-DiagnosticReport-select.html) event is the resources' `id`, as well as its `status` and `code` since these attributes are required by FHIR. Other attributes of the `DiagnosticReport` MAY be valued but would serve no purpose in the [`DiagnosticReport-select`](3-6-4-DiagnosticReport-select.html) event.\n package_name: hl7.fhir.uv.fhircast derivation: constraint name: FHIRcastDiagnosticReportSelect type: DiagnosticReport elements: id: {short: A logical id of the resource SHALL be provided., index: 0} status: {short: 'Status of the DiagnosticReport, note this may not be known and hence have a value of `unknown`; however, is included since it is required by FHIR', index: 1} package_version: 3.0.0-ballot class: profile kind: resource url: http://hl7.org/fhir/uv/fhircast/StructureDefinition/fhircast-diagnostic-report-select base: http://hl7.org/fhir/StructureDefinition/DiagnosticReport version: 3.0.0-ballot required: [id]
