10/21/2021: Lab Alert: CDC Updates LOINC In Vitro Diagnostic (LIVD) Test Code Mapping Tool for SARS-CoV-2 Tests to Include SNOMED-CT Saliva Terms

CDC's Laboratory Outreach Communication System (LOCS)

Audience: Individuals Performing COVID-19 Testing

Level: Laboratory Alert

CDC recently updated its LOINC In Vitro Diagnostic (LIVD) Test Code Mapping Tool for SARS-CoV-2 Tests. The SNOMED-CT for multiple saliva terms listed in Vendor Specimen Description have changed based on input from SNOMED International. Users should select oral saliva “(258560004^Oral saliva sample^SCT)” to identify the specimen if it is from oral saliva. Previous mappings erroneously identified the specimen type as being obtained directly from the salivary gland “(119342007^Saliva specimen^SCT)”.

All changes are listed in the Release Notes tab of mapping tool on the LOINC In Vitro Diagnostic (LIVD) Test Code Mapping for SARS-CoV-2 Tests.
