LIVD – Digital Format for Publication of LOINC to Vendor IVD Test Results
The LIVD specification outlines an industry-defined format to facilitate the publication and exchange of LOINC codes for vendor IVD test results, based on either vendor IVD test transmission codes or manual test identification, for use by laboratory personnel or laboratory applications. The format can be used as-is by IVD software systems to automate the mapping between vendor IVD test transmission codes and LOINC codes, significantly reducing the risk of erroneously mapped test results and units of measure (UCUM).
