Abstract

Discussed herein are methods and apparatuses to produce profiles for scientific measurement equipment, and to use those profiles for various purposes in using, designing, calibrating and managing such equipment, such as to carry out critical laboratory testing. In this approach, either the analyzers' quality control data or serial patient data are numerically reduced to generate graphical precision profiles. Precision profiles for serial patient data show increased (im)precision vs time implying increased patient variation over increased time. Precision profiles for quality control data, according to one implementation, can demonstrate three different zones: 1) increased imprecision for quality control determinations that are close spaced (implies the discovery of an error condition and rapid reanalysis, 2) the usual imprecision and 3) a zone of increased imprecision which indicates either a need for a quality control analysis or re-calibration.
