Abstract	In medical laboratories, a metrological basis for quantitation is missing for many tests. This is recognised by the profession and over the last decade the concept of metrological traceability is advocated. However, daily practice is refractable: for many analytes reference measurement procedures are missing and once in place, clinicians obstruct the new units. This wearisome process is described in general terms and illustrated by the specific case of HbA1c. A working group of the scientific division of the IFCC developed a reference system for this key parameter in diabetes management. This system is worldwide accepted as the analytical anchor. However, clinicians objected the new units. A debate of years followed. This urged the international diabetes organisations IDF, EASD and ADA to find a solution to avoid confusion. They came up with a consensus statement, but this compromise—report of HbA1c in three units—was unpractical and not accepted. Finally, decisions were made at a national level: the European Union and Japan will report in the new units, the US in their old national units and an additional unit, the estimated average glucose.
