What is the LOINC standard and how is it used in health informatics?
LOINC (Logical Observation Identifiers Names and Codes) is a universal standard for identifying medical laboratory observations and clinical measurements, enabling consistent data exchange between health systems.

LOINC is a freely available standard developed by the Regenstrief Institute that provides universal codes for laboratory tests, clinical observations, and measurements. It enables different health information systems to exchange laboratory and clinical data in a standardised way. For example, a malaria rapid diagnostic test result can be coded with a specific LOINC code, allowing the result to be understood by any LOINC-compliant system. In South Sudan, LOINC is relevant for laboratory information systems and electronic health records that need to exchange test results with other systems. OpenMRS supports LOINC coding for laboratory observations.
LOINC is available free at loinc.org and includes a comprehensive database of over 90,000 terms. SSHIA training on clinical informatics and laboratory information systems covers LOINC and its application in South Sudan health facilities.
