Comparing the tested results of QBC Star and Sysmex XP-100 hematology analyzers and analyzing their operational performance / 国际检验医学杂志

ABSTRACT

Objective Both QBC Star and Sysmex XP-100 hematology analyzers are convenient to carry,which can be used nor-mally under the condition of the field(emergency).This study would compare their test results and operating performance,so to provide guidance for rational use of the instruments.Methods 100 fresh blood samples of 100 health soldiers anti-coagulated by EDTA-K2 were detected by QBC Star and Sysmex XP-100 haematology analyzers respectively,the results of two analyzers were comparatively analyzed and their test time and operating convenience were analyzed.Results There was no significant difference in the results of hemoglobin concentration (HGB),hematocrit (HCT)tested by the two methods (P >0.05).There were significant difference of the mean corpuscular hemoglobin concentration (MCHC),the sum of lymphocyte percent and middle type cells (LYM%+MID%),neutrophil percentage(NEUT%),white blood cell count(WBC),platelet count(PLT)tested by the two meth-ods(P <0.05).The values of MCHC and LYM%+MID% tested by the QBC Star were significantly lower than that detected by Sysmex XP-100(P <0.05),while the rest indicators tested by the former were higher than that of the latter.It took about 5 minutes to complete a blood sample analysis with QBC Star,while about 1 min was needed for Sysmex XP-100.Conclusion The test results of QBC Star and Sysmex XP-100 hematology analyzers couldn′t exchanged except for that of HCT and HGB.Under the condition of field(emergency),QBC Star hematology analyzer is suitable for individual medical examination,and Sysmex XP-100 hematology an-alyzer can be used for the batch medical examination.
