Analysis and evaluation of data available in a medical laboratory at estimating measurement uncertainty

The paper analyzes an approach for evaluation of measurement uncertainty in medical laboratory recommended by ISO/TS 20914 “Medical laboratories - Practical guide for the estimation of measurement uncertainty”. Special attention is paid to estimation of measurement precision using of internal quality control data as well as of information provided by manufactures of analytical systems including calibrators (with associated uncertainties) and external quality control using certified reference materials.
