LOINC and Health Data Standards

LOINC^® (short for Logical Observation Identifiers, Names and Codes) is the international standard for identifying health measurements, observations, and documents.

Reference labs, healthcare providers, government agencies, insurance companies, software and device manufacturers, researchers, and consumers from around the globe use LOINC codes to identify data and move it seamlessly across health systems.

The LOINC^® terminology system is:

free to users.
used in nearly every country.
funded by U.S. federal agencies and organizations.
created and maintained at Regenstrief.

Mission

LOINC’s mission is to develop and advance adoption of open data standards that enable efficient transmission, understanding, and use of health data. We want to see open terminology standards integrated into every clinical information system that shares or aggregates data. We are committed to a health ecosystem where data is available with open standards that unlock the potential for information systems and applications to improve health decision-making and care.
