SNOMED Documentation Search
Recommendation:To identify the requested observation/test/battery LOINC should be used as the standard coding system. Alternative 1:The SNOMED CT expression associated with a LOINC code may be used. Alternative 2:SNOMED CT concepts from the 15220000 | Laboratory test| or 363787002 | Observable entity| hierarchies may be used. |

Example 2: Laboratory Orders in National Animal Health Laboratory Network
The NAHLN uses LOINC codes to defining the test or panel/battery ordered as the Universal Service Identifier (OBR-4). In the NAHLN, new tests or panels that do not have an assigned LOINC Code, are identified with an alternative or local identifier.
