ISO/TS 20914:2019 is a technical specification from the International Organization for Standardization (ISO) that provides guidance for medical laboratories on how to estimate and express the measurement uncertainty (MU) of their quantitative results. It also applies to qualitative methods that involve a measurement step. Essentially, this standard helps laboratories understand how their results might vary and how to communicate that variability to users, particularly in clinical settings.
