LOINC Updates

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.

Mayo Clinic Laboratories systematically assigns LOINC values to its assays, as provided in the following spreadsheet.
