The report of the second meeting of the Strategic Advisory Group of Experts on In Vitro was launched in November 2019 and includes the updated WHO Model List of Essential In Vitro Diagnostics (EDL), which lists 122 in vitro diagnostic categories and incorporates evidence base and expositions of the applications to be included on the EDL and the basis of decisions made to list or reject these IVDs. The evidence is expected to guide countries on constituting their national EDLs. In addition the report also presents decision summaries on suggested edits to the first EDL, recommendations on various matters of in vitro diagnostics including the framework for developing future editions, and proposed actions for implementation of the EDL in regions and countries.
