Abstract:
Objective The performance characteristics of statistical quality control procedures in Westgard sigma rule are analyzed by using the power function graph.Methods According to the drawing principle of power function graph,the internal quality control program design software of clinical laboratory quantitative measurement was developed.and the Westgard sigma rule quality control procedures were simulated with power function graph.The performance of the quality control procedures recommended by Westgard sigma was analyzed by combining different sigma quality levels.Results The rules recommended by Westgard sigma were relatively simple rules that can meet the requirements of error detection probability and false rejection probability.Conclusion The internal quality control procedure design software for quantitative clinical testing has verified the performance of Westgard sigma recommendation rules.The Westgard sigma rule diagram is intuitive and convenient,the laboratory can use the Westgard sigma recommendation rules for internal quality control.
