René Dybkær worked on measurement concepts and terminology in laboratory medicine. The IUPAC traceability report identifies him with the Department of Standardization in Laboratory Medicine at Frederiksberg Hospital, Denmark, and names him as a coauthor with Paul De Bièvre, Aleš Fajgelj and David Brynn Hibbert.[ref]
Metrological traceability of measurement results in chemistry: Concepts and implementation by Paul De Bièvre and others. Publisher byline, affiliation2 and Abstract.
The report develops a shared account of metrological traceability for chemical measurement. Such terminology matters because a result must identify the measurand and reference relationship before numerical comparisons become meaningful. A chemical name, number and unit together specify more than an instrument indication alone.
For an original conversion example, a stipulated compound with molar mass at has mass concentration . The numbers2 and200 describe equivalent content under that specification, rather than disagreement between laboratories. Conversely, equal numbers attached to different quantity definitions need not be equivalent. Uncertainty in the inputs also belongs in the conversion's measurement uncertainty.
René Dybkær's coauthored standards work addresses this need to make the meaning of a measurement communicable. The example is an original illustration of the problem, not data attributed to his experiments or a statement of a clinical decision threshold.
