[Recommendations for expressing uncertainty of measurement of quantitative results in laboratory medicine].
In laboratory medicine, the quantitative results of examinations are interpreted with regard to reference intervals, clinical decision limits or previous results of a patient, from which it is necessary to inform the clinician about the uncertainty of measurement linked to the value of the result. This document explains the problematic of the expression of the uncertainty of measurement. It proposes recommendations concerning a simple way to evaluate uncertainty of measurement using long term internal quality control data and the value of the uncertainty linked to the method calibration. It approaches the determination of analytical goals and the choice of methods and also the comments accompanying the record of results and a help to their interpretation.
