SNOMED Documentation Search
The summary information on this page is based on analysis of use cases and guidelines identified during an environmental scan of current usage of LOINC and SNOMED CT in clinical laboratory systems and related healthcare systems.
Table 5.2-1 summarizes recommendations for use of either SNOMED CT or LOINC in particular data elements. The recommendations are subdivided into categories based on particular scenarios or contexts of use. Figure 5.2-1 provides a graphical representation of the current use of SNOMED CT and LOINC for representing particular types of information, as identified in the environmental scan.
