Abstract:
Objective To evaluate the performance of the main indicators in the blood analysis of an occupational health exam ination agency by Sigma verification of performance chart and guide quality improvement.Methods Collected blood testing laboratory internal quality control (IQC) data in October 2016 and 2016 second national external quality assessment (EQA) results of the blood analysis laboratory in the agency.Regarded the accumulated coefficient of variability as the estimation value of imprecision.Used the percentage difference in EQA results as the estimation value of bias (％) of the laboratory.The total allowable error in health industry standard WS/T406-2012 was adopted as the quality specification (％).Sigma verification of performance chart of the main eight projects in the blood analysis were drawn with professional software.Results The sigma value of WBC reached σ≥6 level,as the first-class performance,and the sigma values of HGB in the 4≤σ ＜5 level,test performance was good.The sigma value of Hct,HCV and MCHC all were in the 3≤σ＜4 level,as the critical level,and the sigma values of RBC,platelet and MCH in the 2≤σ＜3 level,as poor performance.Conclusion Sigma verifica tion of performance chart could reflect the level of the laboratory testing performance on different test items of blood count,promote the quality improvement.
