The official URL for this profile is: 

http://hl7.org/fhir/us/core/StructureDefinition/us-core-diagnosticreport-lab

Laboratory results are grouped and summarized using the DiagnosticReport resource which typically reference Observation resource(s). Each Observation resource represents an individual laboratory test and result value or component result values, or a “nested” panel (such as a microbial susceptibility panel) which references other observations. They can also be presented in report form or as free text. This profile sets minimum expectations for the DiagnosticReport resource to record, search, and fetch laboratory results associated with a patient. It identifies which core elements, extensions, vocabularies and value sets SHALL be present in the resource when using this profile.

Example Usage Scenarios:

The following are example usage scenarios for the US Core DiagnosticReport Profile for Laboratory Results Reporting:

  • Query for lab reports belonging to a Patient
  • Record or update a lab report for a specific Patient

Mandatory and Must Support Data Elements

The following data-elements are mandatory (i.e data MUST be present) or must be supported if the data is present in the sending system (Must Support definition). They are presented below in a simple human-readable explanation. Profile specific guidance and examples are provided as well. The Formal Profile Definition below provides the formal summary, definitions, and terminology requirements.

Each DiagnosticReport must have:

  1. a status
  2. a category code of ‘LAB’
  3. a code (preferably a LOINC code) which tells you what is being measured
  4. a patient
  5. a time indicating when the measurement was taken
  6. a time indicating when the measurement was reported

Each DiagnosticReport must support:

  1. who issues the report
  2. 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.

Notes:

Quick Start

Below is an overview of the required set of Server RESTful FHIR interactions - for example, search and read operations - for this profile. See the Capability Statements for a complete list of supported RESTful interactions for this IG.

  • The syntax used to describe the interactions is described here.
  • See the General Guidance section for additional rules and expectations when a server requires status parameters.
  • See the General Guidance section for additional guidance on searching for multiple patients.

Mandatory Search Parameters:

The following search parameters and search parameter combinations SHALL be supported.:

  1. SHALL support searching for all diagnosticreports for a patient using the patient search parameter:

    GET [base]/DiagnosticReport?patient={Type/}[id]

    Example:

    1. GET [base]/DiagnosticReport?patient=1137192

    Implementation Notes: Fetches a bundle of all DiagnosticReport resources for the specified patient (how to search by reference)

  2. SHALL support searching using the combination of the patient and category search parameters:

    GET [base]/DiagnosticReport?patient={Type/}[id]&category=http://terminology.hl7.org/CodeSystem/v2-0074|LAB

    Example:

    1. GET [base]/DiagnosticReport?patient=f201&category=http://terminology.hl7.org/CodeSystem/v2-0074|LAB

    Implementation Notes: Fetches a bundle of all DiagnosticReport resources for the specified patient and a category code = LAB (how to search by reference and how to search by token)

  3. SHALL support searching using the combination of the patient and code search parameters:
    • including optional support for composite OR search on code (e.g.code={system|}[code],{system|}[code],...)

    GET [base]/DiagnosticReport?patient={Type/}[id]&code={system|}[code]{,{system|}[code],...}

    Example:

    1. GET [base]/DiagnosticReport?patient=1032702&code=http://loinc.org|24323-8

    Implementation Notes: Fetches a bundle of all DiagnosticReport resources for the specified patient and report code(s). SHOULD support search by multiple report codes. (how to search by reference and how to search by token)

  4. SHALL support searching using the combination of the patient and category and date search parameters:
    • including support for these date comparators: gt,lt,ge,le
    • including optional support for composite AND search on date (e.g.date=[date]&date=[date]]&...)

    GET [base]/DiagnosticReport?patient={Type/}[id]&category=http://terminology.hl7.org/CodeSystem/v2-0074|LAB&date={gt|lt|ge|le}[date]{&date={gt|lt|ge|le}[date]&...}

    Example:

    1. GET [base]/DiagnosticReport?patient=f201&category=http://terminology.hl7.org/CodeSystem/v2-0074|LAB&date=ge2010-01-14T00:00:00Z

    Implementation Notes: Fetches a bundle of all DiagnosticReport resources for the specified patient and date and a category code = LAB (how to search by reference and how to search by token and how to search by date)

Optional Search Parameters:

The following search parameter combinations SHOULD be supported.:

  1. SHOULD support searching using the combination of the patient and status search parameters:
    • including support for composite OR search on status (e.g.status={system|}[code],{system|}[code],...)

    GET [base]/DiagnosticReport?patient={Type/}[id]&status={system|}[code]{,{system|}[code],...}

    Example:

    1. GET [base]/DiagnosticReport?patient=1137192&status=completed

    Implementation Notes: Fetches a bundle of all DiagnosticReport resources for the specified patient and status (how to search by reference and how to search by token)

  2. SHOULD support searching using the combination of the patient and code and date search parameters:
    • including optional support for composite OR search on code (e.g.code={system|}[code],{system|}[code],...)
    • including support for these date comparators: gt,lt,ge,le
    • including optional support for composite AND search on date (e.g.date=[date]&date=[date]]&...)

    GET [base]/DiagnosticReport?patient={Type/}[id]&code={system|}[code]{,{system|}[code],...}&date={gt|lt|ge|le}[date]{&date={gt|lt|ge|le}[date]&...}

    Example:

    1. GET [base]/DiagnosticReport?patient=f201&code=http://loinc.org|24323-8&date=ge2019-01-14T00:00:00Z

    Implementation Notes: Fetches a bundle of all DiagnosticReport resources for the specified patient and date and report code(s). SHOULD support search by multiple report codes. (how to search by reference and how to search by token and how to search by date)
