11 Logical Observation Identifiers Names and Codes Regenstrief Institute in Indiana, USA A definitive standard for identifying clinical information in electronic reports. LOINC codes are intended to identify the test result or clinical observation.

12 SNOMED (SNOMED-CT-AUS) Systematized Nomenclature of Medicine Systematically organised computer processable collection of medical terms providing codes, terms, synonyms and definitions covering diseases, clinical findings, procedures, microorganisms, substances Owned and maintained SNOMED International (prev IHTSDO) Managed and distributed in Australia by ADHA
