Introducing the LOINC Ontology: A LOINC and SNOMED CT Interoperability Solution
ABOUT THIS PROJECT A new cooperative agreement was signed between the Regenstrief Institute (RII) and SNOMED International (IHTSDO) in October 2022. The organizations agreed to work together to minimize duplication between LOINC and SNOMED CT and to enhance the ability of stakeholders to use the two terminologies together. A primary aim of the agreement is to create an extension of SNOMED CT for the LOINC terminology. This effort builds on strengths of both terminologies by increasing the computability of LOINC and making the more granular observables in LOINC available to be used in a SNOMED format integrated with SNOMED CT concepts.
