HL7 Austria ELGA Laboratory Report R4 — Implementation Guide

Version: 0.1.0 (CI Build) Status: Draft Realm: Austria (AT) FHIR Version: R4 (4.0.1)

Overview

This FHIR R4 Implementation Guide (IG) defines the Austrian ELGA Laboratory Report (Laboratoriumsbefund) standard. It enables structured, interoperable exchange of in-vitro diagnostic laboratory results within the Austrian Electronic Health Record system (ELGA — Elektronische Gesundheitsakte) and supports cross-border exchange via MyHealth@EU.

The IG is derived from the HL7 Europe Laboratory Report IG (v0.1.1) and aligns with the HL7 Austria Core R4 profiles (v2.0.0), combining European harmonisation with Austrian national requirements.

Scope

This IG covers in-vitro diagnostic laboratory domains including:

Domain Beispiel
Clinical Biochemistry Blutchemie, Elektrolyte, Enzyme
Haematology Großes/Kleines Blutbild, Gerinnungsdiagnostik
Microbiology Bakteriologie, Virologie, Parasitologie
Immunology & Serology Antikörper, Autoimmundiagnostik
Toxicology Medikamenten-Monitoring, Drogen-Screening
Molecular Diagnostics PCR, genetische Untersuchungen

Out of scope: Histopathology, cytology, radiology, and other non-laboratory diagnostics.

Relationship to Parent IGs

What this IG inherits from the EU Lab IG

  • Bundle/Composition/DiagnosticReport/Observation structure for laboratory reports
  • EU-harmonised value sets (LOINC, SNOMED CT, UCUM, NPU)
  • MyHealth@EU cross-border interoperability constraints
  • Legal signing capability via the Bundle document paradigm
