# DiagnosticReport Definitions

<a id="DiagnosticReport"></a>

## DiagnosticReport
A Diagnostic report - a combination of request information, atomic results, images, interpretation, as well as formatted reports

**Definition:** The findings and interpretation of diagnostic tests performed on patients, groups of patients, products, substances, devices, and locations, and/or specimens derived from these. The report includes clinical context such as requesting provider information, and some mix of atomic results, images, textual and coded interpretations, and formatted representation of diagnostic reports. The report also includes non-clinical context such as batch analysis and stability reporting of products and substances.

**Comments:** This is intended to capture a single report and is not suitable for use in displaying summary information that covers multiple reports.  For example, this resource has not been designed for laboratory cumulative reporting formats nor detailed structured reports for sequencing.

**Aliases:** Report, Test, Result, Results, Labs, Laboratory, Test Report

**Cardinality:** 0..*

**Constraints:** dgr-1 | error | When a Composition is referenced in `DiagnosticReport.composition`, all Observation resources referenced in `Composition.entry` must also be referenced in `DiagnosticReport.result` or in the `Observation.hasMember` references. | composition.exists() implies (composition.resolve().section.entry.reference.all($this.resolve() is Observation implies $this in (%resource.result.reference|%resource.result.reference.resolve().hasMember.reference)))

**Definition:** Details concerning a service requested.

**Comments:** Note: Usually there is one test request for each result, however in some circumstances multiple test requests may be represented using a single test result resource. Note that there are also cases where one request leads to multiple reports.

**Requirements:** This allows tracing of authorization for the report and tracking whether proposals/recommendations were acted upon.

**Aliases:** Request

**Cardinality:** 0..*

**Type:** Reference([CarePlan](/CarePlan), [MedicationRequest](/MedicationRequest), [NutritionOrder](/NutritionOrder), [ServiceRequest](/ServiceRequest))

**Cardinality:** 1..1

**Type:** [code](/code)

**Binding:** required:[diagnostic-report-status](/valueset-diagnostic-report-status)

**Summary:** true

**Is Modifier:** true (Reason: This element is labeled as a modifier because it is a status element that contains status entered-in-error which means that the resource should not be treated as valid)

**Mappings:** workflow=Event.status; w5=FiveWs.status; v2=OBR-25 (not 1:1 mapping); rim=statusCode  Note: final and amended are distinguished by whether observation is the subject of a ControlAct event of type "revise"

**Cardinality:** 0..*

**Type:** [RelatedArtifact](/RelatedArtifact)


<a id="DiagnosticReport.encounter"></a>

## DiagnosticReport.encounter
Encounter associated with the DiagnosticReport

**Definition:** The encounter (e.g. a patient and healthcare provider interaction) that is associated with the DiagnosticReport.

**Comments:** This will typically be the encounter, when it exists, during which the data or specimens (e.g. imaging, blood draw, or assessment procedure) that are being reported by the DiagnosticReport were obtained/acquired. When a DiagnosticReport is based on a ServiceRequest (order), the ServiceRequest.encounter referenced in DiagnosticReport.basedOn may be used to associate the two.

**Aliases:** Context

**Cardinality:** 0..1

**Type:** Reference([Encounter](/Encounter))

**Summary:** true

**Mappings:** workflow=Event.encounter; w5=FiveWs.context; v2=PV1-19; rim=inboundRelationship[typeCode=COMP].source[classCode=ENC, moodCode=EVN]


<a id="DiagnosticReport.effective[x]"></a>

## DiagnosticReport.effective[x]
Clinically relevant time/time-period for the results that are included in the report

**Definition:** The time or time-period the observed values are related to. When the subject of the report is a patient, this is usually either the time of the procedure or of specimen collection(s), but very often the source of the date/time is not known, only the date/time itself.

**Comments:** If the diagnostic procedure was performed on the patient, this is the time it was performed. If there are specimens, the diagnostically relevant time can be derived from the specimen collection times, but the specimen information is not always available, and the exact relationship between the specimens and the diagnostically relevant time is not always automatic.

## DiagnosticReport.performer
Responsible Diagnostic Service

**Definition:** The diagnostic service that is responsible for issuing the report.

**Comments:** This is not necessarily the source of the atomic data items or the entity that interpreted the results. It is the entity that takes responsibility for the clinical report.  In the regulated context of diagnostic laboratory work on humans, it is extremely likely that regulation requires a human performer.  Point of care testing, veterinary testing, drug screens, and environmental surveillance are common cases where the device is the performer with no additional human interaction or direct oversight.

<a id="DiagnosticReport.study"></a>

## DiagnosticReport.study
Reference to full details of an analysis associated with the diagnostic report

**Definition:** One or more links to full details of any study performed during the diagnostic investigation. An ImagingStudy might comprise a set of radiologic images obtained via a procedure that are analyzed as a group. Typically, this is imaging performed by DICOM enabled modalities, but this is not required. A fully enabled PACS viewer can use this information to provide views of the source images. A GenomicStudy might comprise one or more analyses, each serving a specific purpose. These analyses may vary in method (e.g., karyotyping, CNV, or SNV detection), performer, software, devices used, or regions targeted.

**Comments:** For laboratory-type studies like GenomeStudy, type resources will be used for tracking additional metadata and workflow aspects of complex studies. ImagingStudy and the media element are somewhat overlapping - typically, the list of image references in the media element will also be found in one of the imaging study resources. However, each caters to different types of displays for different types of purposes. Neither, either, or both may be provided.
