Abstract
Objective To evaluate the major performance of the five categories Coulter Gen S hematology analyzer introduced in our hospital.Methods By matching with the original quality control materials and patient specimens,to evaluate the performance of repeatability,carrying contamination rate,linear and leukocyte classification.Results The mean intra-precision(CV)and total Mutation rate(TCV)of white blood cell (WBC),hemoglobin(Hb)and mean corpuscle volume(MC V)were less than 2 %,the CV and TCV of platelet (PLT)was less than 3 %,carrying contamination rate was close to 0,parameters of linear correlation coefficient r =0.988-0.998.With the correlation comparison of leukocyte classification and microscopic examination,r = 0.988 in neutrophil,r =0.979 in lymphocyte,r =0.912 in eosinophil,r =0.827 in basophil,r =0.856 in monocyte.Conclusion The main performance of the five categories Coulter Gen S hematology analyzer introduced in our hospital were very good.It was full-automatic hematology analyzer which could be used in the effective screening of Blood cell count and classification of whole blood samples in clinical laboratory,and could meet clinical requirements. Key words: Hematology analyzer; Blood corpuscle counting; Evaluation
