Logical Observation Identifiers Names and Codes (LOINC®) is clinical terminology that is important for laboratory test orders and results, and is one of a suite of designated standards for use in U.S. Federal Government systems for the electronic exchange of clinical health information.
In 1999, LOINC was identified by the HL7 Standards Development Organization as a preferred code set for laboratory test names in transactions between health care facilities, laboratories, laboratory testing devices and public health authorities. In the future, LOINC is likely to become a HIPAA standard for certain segments of the Claims Attachment transaction.
This spreadsheet is accurate as of the current date. Detailed setup files in the online Test Catalog now include available LOINC values for individual tests and are recommended for new builds.
