Producing a reliable, reproducible, accurate, timely, and correctly interpreted test results by clinical laboratory is very important, since physicians’ decisions mostly depends on it for screening, diagnosis and monitoring diseases. To provide quality report, routinely in all clinical laboratories internal quality control (IQC) and external quality assessment (EQA) programs are done which helps to evaluate and continuously improve analytical quality. Recently new quality assessment (QA) systems, six-sigma became more popular because it offers a different approach to problems. Sigma metrics allow comparison of different processes with each other and thus improving the quality of testing processes. This study was done to evaluate clinical chemistry laboratory performance using sigma metrics.

Keywords: Internal quality control, External quality assessment programs, Laboratory, Sigma metrics, Six-sigma.
