Toward harmonization of interpretive commenting of common laboratory tests

Few studies that demonstrate evidence on the clinical utility of IC are available in the literature. To set a strategy on further steps toward harmonization in IC, well-controlled clinical studies need to be conducted, in collaboration with laboratories and their users on the clinical usefulness of IC. Until enough evidence on the value of IC in patient outcomes accumulates, standards of qualification and training for performing IC and more EQA schemes in native languages of the users are required to improve the quality of IC.
