Abstract:
Objective To evaluate the analytical performance of lipid testing with six sigma(a) in order to promote the quality improvement.Methods Sixty-four Laboratories participated in trueness verification program and Internet-Based Interlaboratory Comparison of Internal Quality Control Data program lipid testing in 2012 were included in this study.The CVs and Bias of TC,TG,HDL-C,and LDL-C for each laboratory were evaluated from the reporting data.The sigma metrics based on the Tea from National Cholesterol Education Program according to the formula:σ =(TEa-Bias)/CV for each analyte.Quality goal index (QGI) was also calculated to investigate the reason for dissatisfied performance as follows:QGI =Bias/ (1.5CV).Results The rates for σ≥6 of TC,TG,HDL-C,and LDL-C were 21.9%,34.4%,9.38%,and 18.8%,respectively.The corresponding rates for 3 ≤ σ < 6 were 31.3%,29.7%,29.7%,and 34.4%,while the rates for σ < 3 were 46.9%,35.9%,60.9%,and 46.9%,severally.For analytes which σ were less than 3,91.3%-100% of the laboratories should improve the trueness first,0.00%-8.75% of the laboratories should improve the precision,and 0.00%-2.08% should improve both.Conclusions Six sigma is an effective tool for quality control in clinical laboratory,which can help improve the quality level for laboratory testing.The analysis of performance of the lipid testing shows that further effort is acquired to enhance the supervision of the trueness verification.
