Abstract

The knowledge of measurement uncertainty is important to judge the diagnostic power of quantitative methods in laboratory medicine. DIN EN ISO 15189 demands the estimation and the evaluation of measurement uncertainty. The AG Guide Limits of the DGKL developed a concept to derive permissible limits for analytical imprecision and bias considering diagnostic requirements and technical state-of-the art. Analytical imprecision, bias and combined uncertainty are expressed as a function of the empirical biological variation. An option avoiding the influence of bias by using intra-laboratory reference intervals is proposed.
