Abstract

Background: Six Sigma is a powerful tool which can be used by laboratories for assessing the method quality, optimizing internal quality control procedure, change the number of rules applied, and frequency of controls run. Objectives: To evaluate the quality and optimizing internal quality control procedure for some biochemical tests on the automatic biochemical analyzer Beckman Coulter AU480. Materials and methods: A cross-sectional descriptive study on the internal quality control and external quality assessment results of biochemical tests from 04/2023 to 12/2023 at Phuong Chau International Hospital. Results: The laboratory's  biochemical  tests  have  sigma  values >6 at  both  concentrations,  including:  Uric Acid and Trigylceride. The test has a value of 3<sigma<6 at both levels including: AST, ALT, Glucose and Cholesterol. Conclusions: All biomedical tests in the study achieved sigma values at “acceptable” standards or higher. Six Sigma metrics can be a more efficient way to control quality by matching the internal quality control rules to the analytical quality of each individual assay.
