# Laboratory Results Reporting

## Overview

Laboratory Results Information addresses:

* Laboratory Results DiagnosticReport HL7® FHIR® resource with [US Core Profile 6.1.0](https://hl7.org/fhir/us/core/STU6.1/StructureDefinition-us-core-diagnosticreport-lab.html)

Laboratory Results are represented as an FHIR Diagnostic Report object. A diagnostic report is the set of information that is typically provided by a diagnostic service when investigations are complete. The information includes a mix of atomic results, text reports, images, and codes.

**Each DiagnosticReport has next elements:**

* a status
* a category code of ‘LAB’
* a code (preferably a LOINC code) which tells you what is being measured
* a patient
* the diagnostically relevant time (known as the “effective time” and typically the time of specimen collection)\*
* when the report was released

**Each DiagnosticReport supports next elements:**

* who issues the report
* a result

**Profile specific implementation guidance:**

* Additional codes that translate or map to the DiagnosticReport codes or category codes are allowed. For example:
  * providing both a local system codes and a LOINC code that it map to
  * providing a more specific category codes to the “LAB” category code, such as “CH” (chemistry), in an additional coding element.
* Results that are free text or report form are represented using the ‘presentedForm’ element in DiagnosticReport.

This resource conforms to [USCDI V3 profile](https://www.healthit.gov/isp/uscdi-data-class/laboratory#uscdi-v3) for DiagnosticReport - refer to [StructureDefinition US Core DiagnosticReport Lab](https://hl7.org/fhir/us/core/STU6.1/StructureDefinition-us-core-diagnosticreport-lab.html). DiagnosticReport response will be provided in JSON (refers to Capability Statement) format as per [FHIR](https://hl7.org/fhir) standard R4 version.
