Analyse of verification testing result of hematology analyzer

Objective To evaluate the accuracy and the consistency of the result which was got by different types of hematology analyzer in the routine work.Methods The Gen-s System2 hematology analyzer was used to determine 40 blood specimens,which included high,middle and low classes.Every specimen was parallelly determined two times by the same instrument.The mean value was used to analyze several parameters and the results,which were determined by other types of hematology analyzer,were evaluated in items including WBC,RBC,HGB,PLT,HCT got by Gen-s System2 hematology analyzer.Results(1)The accuracy of four Hematology analyzers was good.(2)The results of t-test in WBC,RBC,HGB,PLT and HCT showed that there are no statistical differences(P0.05).(3)Compared to instrument parameter,the correlation coefficient of each instrument were good(r0.975).(4)Compared with the regression curve and the regression equation,the error of each instrument system was known.Conclusion(1)The system error between instrument is promptly found through the test of evaluating the fresh and whole blood by hematology analyzer.(2)The accuracy and the consistency of the result,got by hematology analyzer in the identical laboratory,can be enhanced and guaranteed with the verification testing of hematology analyzer in determining the fresh and whole blood specimen in the identical laboratory.
