The Quality Control Level Analysis of FAPAS Examining Lab's Performance Assessments

[Objective] To analyze the result of international performance assessment,which comparing our laboratory of chemical test with FAPAS,and discuss the efficient quality control measure in performance assessment.[Methods]In order to evaluate and dominate fully any uncertain factors,some certifiable testing methods were chosen,and reasonable testing technology was used in our performance assement scheme.|Z| value is an index for evaluating performance assessment of our lab.[Results] Through the effective quality control measures,in the 10 performance assessments,the qualified rate of the fixed quality parameters has reached 100% in our testing lab,and the qualified rate of the fixed quantity parameters has reached 94.2%.[Conlusion] In our lab these testing results would have been awarded a Satisfactory Z-score with FAPAS.Quality control measures played an important role in the proficiency test.
