Trial Version: The current version is a reference table of the codes related to the IVD tests of the WHO essential in vitro list.

Noting that the codes, term and definitions are not yet embedded in each of the type of tests description page. However, future developments will associate each diagnostic category with a GMDN Code and eventually a European Medical Device Nomenclature (EMDN) code as well, directly in the test type profile.

Upcoming Updates: WHO anticipates updating the electronic EDL (eEDL) during the first quarter of 2025, aligning with ongoing updates to the 5th EDL.
