Lithuanian Laboratory Implementation Guide
0.0.1 - ci-build
Lithuanian Laboratory Implementation Guide, published by Lithuanian Medical Library. This guide is not an authorized publication; it is the continuous build for version 0.0.1 built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/HL7LT/ig-lt-lab/ and changes regularly. See the Directory of published versions
This page summarizes the terminology (ValueSets and CodeSystems) used in the Lithuanian Laboratory IG. For full definitions and bindings, see Artifacts.
Why this matters: Consistent codes and units enable interoperable exchange between laboratory systems, EHRs, and national registries. Standardised bindings support correct data capture, automated validation, and reliable use in clinical decision support.
