Overview
EN ISO 18812:2003 (ISO 18812:2003) - "Health informatics - Clinical analyser interfaces to laboratory information systems - Use profiles" - defines standard, character‑based message profiles and syntax for electronic data exchange between analytical instruments (AIs) and laboratory information systems (LISs) in clinical laboratories. Adopted by CEN, this standard targets specialties such as clinical chemistry/biochemistry, haematology, toxicology, microbiology, virology and immunology. It does not apply to blood transfusion/blood bank specialties, graphical/image data, or the transport mechanisms used to carry messages.
Key Topics
- Message profiles and descriptions: standard ways of conveying the same information so implementers exchange data consistently.
- Character‑based syntax: specification applies only to character data (no images/graphics).
- Scope of specialties: clinical chemistry/biochemistry, haematology, toxicology, microbiology, virology, immunology.
- Conformance and profiling: rules for levels of complexity and conformity to enable simpler, repeatable interfaces.
- Sequence diagrams and scenarios: illustrative models and interaction sequences to guide implementation.
- Attribute optionality and allowed values: guidance on which data items are required or optional and permitted values to reduce ambiguity.
- Implementation guidance for quality management: recommendations to support laboratory accreditation needs (e.g., data required by ISO/IEC 17025), provided in informative annexes.
Applications and Who Uses It
This standard is practical for organizations and roles focused on clinical laboratory IT integration:
- LIS vendors and integrators-to implement standardized AI interfaces and reduce custom interface development costs.
- Analytical instrument manufacturers-to produce AI firmware/software that communicates in standard message formats.
- Clinical laboratory IT teams-to design, validate and maintain interfaces between instruments and LIS for accurate result capture and reporting.
- Quality and compliance officers-to ensure data required for laboratory accreditation and quality management is captured and transmitted.
- Healthcare IT architects-to plan interoperable laboratory workflows and reduce vendor lock‑in.
Benefits include lower interface development cost, fewer bespoke adapters, clearer implementation guidance, and improved interoperability across clinical analyser ecosystems.
