# US Quality Core DiagnosticReport Profile for Laboratory Results Reporting - 2026 US Quality Core Implementation Guide v0.5.0

## Resource Profile: US Quality Core DiagnosticReport Profile for Laboratory Results Reporting 

 
Profile of DiagnosticReport for laboratory results for decision support/quality metrics. Defines the core set of elements and extensions for quality rule and measure authors. 

### USCDI+ Quality Element Support Expectations

Systems are expected to support this profile as part of implementing USCDI+ Quality V1 in FHIR and meeting the conformance requirements of this guide.

The following elements are specifically relevant to USCDI+ Quality V1 data classes and elements. Systems are expected to support these elements as applicable to their role in US Quality Core data exchange. See the [Must Support](must-support.md) section of this guide for more information. These elements are tagged as (USCDI+ Quality) in the formal profile views.

**USCDI+ Quality Elements:**

* status: (USCDI+ Quality) (USCDI) registered | partial | preliminary | final +
* category: (USCDI+ Quality) (USCDI) Service category
* category:LaboratorySlice: (USCDI+ Quality) (USCDI) Service category
* code: (USCDI+ Quality) (USCDI) US Core Laboratory Report Order Code
* effective[x]: (USCDI+ Quality) (USCDI) Diagnostically relevant time (typically the time of specimen collection)
* result: (USCDI+ Quality) (USCDI) Observations

Because this profile is derived from US Core, systems are also expected to support Must Support requirements and (USCDI) tagged elements inherited from US Core. The [Formal Views](#profile) section also provides the formal summary, definitions, terminology requirements, and mandatory element requirements.

**Usages:**

* Examples for this Profile: [DiagnosticReport/example](DiagnosticReport-example.md)
* CapabilityStatements using this Profile: [US Quality Core Client CapabilityStatement](CapabilityStatement-us-quality-core-client.md) and [US Quality Core Server CapabilityStatement](CapabilityStatement-us-quality-core-server.md)
