【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(MCV)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.
