LOINC Ontology
A LOINC and SNOMED CT Interoperability Solution
The LOINC Ontology supports providers and users who implement different combinations of SNOMED CT and LOINC in health information systems and allows them to meet clinical and regulatory requirements in a single solution.
An extension of SNOMED CT’s ontological framework, the ontology creates SNOMED CT and LOINC codes for all concepts that are shared between the terminologies. SNOMED CT provides the computable framework and LOINC provides laboratory and pathology content in an understood format to countries that do not currently use LOINC.
More information is available on the collaboration website: loincsnomed.org
Join us for a special webinar to discuss the first production release of the LOINC Ontology
The March 2025 release will include more than 35,000 concepts, including quantitative lab tests and the top 200 most used labs. Domains of information (lab, clinical, documents, radiology, survey instruments) will be added incrementally.
Existing LOINC concepts will be represented in a SNOMED CT format, using dual identifiers, with LOINC Parts mapped to SNOMED attributes.
