Quality Management
Want to know just how much your error detection is? What precisely your false rejection is? For all the methods in your laboratory? Critical-Error graphs are powerful tools that tell you quickly how well your method is performing.
Power Function Graphs are statistical tools. They reveal the performance of the statistical rules used in the laboratory. Why do those 12s rules have so many repeat runs? One power function graph will explain it to you.
How do you design quality? Not by throwing darts at a Levey-Jennings charts. You have to choose methods, numbers of materials and controls, control rules, and more. You need a design (or planning) process for your QC. Here's the one that Dr. Westgard recommends.
QC Validator is a software program that chooses control rules to meet any quality requirement you specify. Version 2.0, described in this lesson, has automatic QC selection with user-defined selection criteria and logic. If you want to know more about its features and possibilities, read this lesson.
