LOINC (Logical Observation Identifiers Names and Codes) - CSV
LOINC (Logical Observation Identifiers Names and Codes) is an international standard code system for identifying clinical laboratory tests and healthcare observations. Developed by the Regenstrief Institute in the United States in 1994, it is now used in over 172 countries and adopted as a national standard in more than 15 countries. LOINC consists of two major divisions: Laboratory LOINC (specimen-based tests) and Clinical LOINC (clinical observations). By structuring test items using six axes - Component, Property, Time, System, Scale, and Method - LOINC enables accurate data exchange between healthcare institutions worldwide.
