Harmonization of diagnostic test results is fundamental to the effective use of laboratory testing in the diagnosis, treatment and monitoring of disease. Formal approaches to harmonization and standardization provide a rigorous and high quality Roadmap to this end, though the formal harmonization process can be long and complex. In the meantime, more informal approaches to harmonization can provide a useful pathway to improved harmonization in the short term. Factors relevant to harmonization are discussed with particular attention to protein assays employing LC- MS/MS. Published formal and informal harmonization projects are provided as examples, including lessons drawn from these projects.
