  • Binding to Austrian laboratory code value set (extends EU Lab codes with Austrian-specific codes)

This profile covers in-vitro diagnostic laboratory test results including clinical biochemistry, haematology, microbiology, and immunology.
AT ELGA Laboratory Report Bundle

FHIR Bundle for Austrian ELGA Laboratory Reports.

Extends the HL7 Europe Laboratory Report Bundle with Austrian-specific requirements:

  • Mandatory Austrian business identifier using the GDA (Gesundheitsdiensteanbieter) OID namespace
  • Entries referencing Austrian-profiled resources (AT ELGA Lab profiles)

This bundle represents a legally signable, self-contained laboratory report document.
AT ELGA Laboratory Report Composition

Composition profile for Austrian ELGA Laboratory Reports.

Extends the HL7 Europe Laboratory Report Composition with Austrian-specific requirements:

  • Subject SHALL reference an AT ELGA Lab Patient
  • Author SHALL reference an AT ELGA Lab Practitioner, PractitionerRole, or Organization
  • Custodian SHALL reference an AT ELGA Lab Organization (the responsible GDA)
  • Austrian language requirement (de-AT preferred)

The Composition acts as the clinical document header for the laboratory report and links to the DiagnosticReport containing the structured results.

Participant Profiles

Profiles for persons and organizations involved in laboratory reporting

AT ELGA Laboratory Organization

Organization profile for Austrian ELGA Laboratory Reports.

Derives from the HL7 Austria Core Organization profile and adds laboratory-specific requirements:

  • Organization type SHALL include a laboratory type code
  • GDA-OID identifier is strongly recommended
  • Austrian hospital number (Krankenanstaltennummer / KANR) or VPNR for contracted labs

This profile covers both hospital laboratories (Krankenhauslabors) and independent medical laboratories (Selbstständige Ambulatorien / Labore).
AT ELGA Laboratory Patient

Patient profile for Austrian ELGA Laboratory Reports.

Extends the HL7 Europe Laboratory Patient profile with Austrian-specific identifiers and extensions as defined in the HL7 Austria Core R4 profiles:

Austrian Identifiers:

  • Sozialversicherungsnummer (SVNR) — Austrian social security number
  • Bereichsspezifisches Personenkennzeichen (bPK) — sector-specific personal identifier
  • Lokale Patientennummer — local patient identifier assigned by the GDA

Austrian Extensions (from AT Core):

  • Patient religion (PatientenReligion)
  • Administrative gender addition (for official Austrian gender categories)

Address:

  • Address SHALL use the AT Core Address profile (with street, street number, municipality code)
AT ELGA Laboratory Practitioner

Practitioner profile for Austrian ELGA Laboratory Reports.

Extends the HL7 Europe Laboratory Practitioner profile with Austrian-specific identifiers as defined in the HL7 Austria Core R4 profiles:

Austrian Identifiers:

  • GDA-OID — OID identifying the practitioner as a Gesundheitsdiensteanbieter
  • VPNR (Vertragspartnernummer) — contract partner number assigned by health insurance carriers
  • vbPK (Verschlüsseltes bereichsspezifisches Personenkennzeichen) — encrypted sector-specific identifier

Extensions:

  • Administrative gender addition (for official Austrian gender categories)
AT ELGA Laboratory PractitionerRole

PractitionerRole profile for Austrian ELGA Laboratory Reports.

Extends the HL7 Europe Laboratory PractitionerRole profile and aligns with the HL7 Austria Core PractitionerRole profile:

  • practitioner SHALL reference an AT ELGA Lab Practitioner
  • organization SHALL reference an AT ELGA Lab Organization
  • Austrian specialty codes (Sonderfachbezeichnungen)

Supporting Profiles

Supporting resource profiles for orders and specimens

AT ELGA Laboratory ServiceRequest (Order)

ServiceRequest profile for Austrian ELGA Laboratory Orders (Laboraufträge).

Extends the HL7 Europe Laboratory Order ServiceRequest with Austrian-specific requirements:

  • subject SHALL reference an AT ELGA Lab Patient
  • requester SHALL reference an AT ELGA Lab Practitioner, PractitionerRole, or Organization
  • performer SHALL reference an AT ELGA Lab Organization (the laboratory)
  • Austrian order identifier using the ordering GDA's OID namespace

This profile represents the laboratory order placed by an ordering physician (Einsender) to a performing laboratory (auftragnehmende Labor).
AT ELGA Laboratory Specimen

Specimen profile for Austrian ELGA Laboratory Reports.

Extends the HL7 Europe Laboratory Specimen profile with Austrian-specific requirements:

  • subject SHALL reference an AT ELGA Lab Patient
  • Collection performed by an AT ELGA Lab Practitioner or PractitionerRole
  • Accession identifier using the receiving laboratory's OID namespace

Covers all specimen types used in in-vitro diagnostic laboratory testing in Austria.

Terminology: Value Sets

These define sets of codes used by systems conforming to this implementation guide.

AT ELGA Laboratory Code Value Set

Value set for laboratory test codes used in Austrian ELGA Laboratory Reports.

Includes LOINC codes as the primary coding system (aligned with the HL7 EU Lab IG) and allows supplementary local Austrian codes. NPU codes are also included for compatibility with the European Lab IG.
AT ELGA Laboratory Practitioner Specialty Value Set

Value set for Austrian medical specialties (Sonderfachbezeichnungen) relevant to laboratory medicine. Based on the official Austrian Ärztegesetz specialties.
AT ELGA Laboratory Report Type Value Set

Value set for types of laboratory reports submitted to Austrian ELGA.
AT ELGA Laboratory Result Interpretation Value Set

Value set for laboratory result interpretations used in Austrian ELGA Laboratory Reports. Aligned with the HL7 ObservationInterpretation code system.
AT ELGA Laboratory Specimen Type Value Set

Value set for specimen types used in Austrian ELGA Laboratory Reports. Based on SNOMED CT specimen concepts.

Terminology: Code Systems

These define new code systems used by systems conforming to this implementation guide.

AT ELGA Laboratory Local Code System

Local code system for Austrian laboratory test codes not covered by LOINC or NPU. These codes are managed by the Austrian laboratory quality assurance authority (ÖQUASTA/AGES) and should be used only when no suitable LOINC or NPU code exists.

Note: This code system is a placeholder. Implementers should reference the current Austrian laboratory code catalogue published by the relevant Austrian authority.
AT ELGA Laboratory Practitioner Specialty Code System

Austrian medical specialty codes (Sonderfachbezeichnungen) relevant to laboratory medicine, based on the Austrian Ärztegesetz (ÄrzteG 1998).

Example: Example Instances

These are example instances that show what data produced and consumed by systems conforming with this implementation guide might look like.

Example AT ELGA Lab Bundle — Großes Blutbild
