Application of Sigma Metrics for Quality Improvement in OGH Laboratory's Analytical Chemistry

Dr. Swarna Latha, Dr. Sujatha Rani

Abstract: This study explores the application of sigma metrics as a tool for improving quality in the OGH laboratory?s analytical chemistry processes. The research uses IQC EQC data from Aug 2021 to Dec 2021, and the results show significant improvements in certain areas, with Uric acid and ALP showing world class quality results. The study concludes with recommendations for more stringent application of Westgard rules for analytes with ?<3.
