Sažetak
Sigma metrics have become a useful tool for all parts of the quality control (QC) design process. Through the allowable total error model of laboratory
testing, analytical assay performance can be judged on the Six Sigma scale. This not only allows benchmarking the performance of methods
and instruments on a universal scale, it allows laboratories to easily visualize performance, optimize the QC rules and numbers of control measurements
they implement, and now even schedule the frequency of running those controls.
