The main goal of this IG is the definition of the proper data exchange format. The following provides a general process context from the initial creation of the LIVD Catalog and its use by the laboratory.
The device manufacturer creates the LIVD mappings based on their intended use of IVD Test Performed and Coded Result Values relative to the appropriate LOINC and/or SNOMED codes. The manufacturer is expected to make the LIVD Catalog available in accordance with this LIVD IG defined format. The FHIR-based LIVD Catalog mwy actually be generated from a spreadsheet based mapping based on the LOINC transmission document for IVDs (LIVD) standard, which is a standard explicitly developed for this purpose by the IVD Industry Connectivity Consortium (IICC). They may use their own spreadsheet formats as well.
The manufacturer may provide the LIVD Catalog using any of the following methods and may include a spreadsheet format as well for human readability when not used in its electronic form by the receiver:
An intermediary organization may gather LIVD catalogs from multiple vendors and makes those available through a library that laboratories and/or LIS systems can access.
A laboratory may receive the LIVD Catalog in varying forms, directly from the manufacturer or through an intermediary party:
When displaying the information to those configuring the mappings between IVD Test Performed and the appropriate LOINC codes, one must consider the relevant data to assist in the mapping. We provide the following guidance for consideration:
