This document provides practical guidance for the estimation and expression of the measurement uncertainty (MU) of quantitative measurand values produced by medical laboratories. Quantitative measurand values produced near the medical decision threshold by point-of-care testing systems are also included in this scope. This document also applies to the estimation of MU for results produced by qualitative (nominal) methods which include a measurement step. It is not recommended that estimates of MU be routinely reported with patient test results, but should be available on request.Cross References:ISO 15189:2012ISO 17511:2003IEC 60050-300:2001JCGM 200:2012ISO/IEC 80000-1:2009JCGM 100:2008ISO/TS 21748:2010
