2种血常规分析仪检测结果的比较及其使用性能分析

Comparing the tested results of QBC Star and Sysmex XP-100 hematology analyzers and analyzing their operational performance

目的对QBC Star和Sysmex XP-100 2种血常规分析仪进行检测,并对使用性能进行比较分析,为野战应急条件下两者的合理选用提供指导。方法使用QBC Star和Sysmex XP-100血常规分析仪检测100例健康战士EDTA-K2抗凝静脉血样,并对其检测指标和检测时间及操作便捷性进行比较分析。结果 QBC Star和Sysmex XP-100检测血红蛋白(HGB)、红细胞压积(HCT)结果差异无统计学意义(P>0.05);平均红细胞血红蛋白浓度(MCHC)、淋巴细胞和中间细胞百分比(LYM%+MID%)、中性粒细胞百分比(NEUT%)、白细胞(WBC)、血小板(PLT)检测结果差异具有统计学意义(P<0.05)。其中,QBC Star检测的MCHC和LYM%+MID%显著低于Sysmex XP-100的检测结果(P<0.05),而其余3项指标则高于后者测定结果。QBC Star检测1个血样约5min,Sysmex XP-100检测1个血样约1min。结论除HGB和HCT外,QBC Star和Sysmex XP-100的检测结果不可互换。在野外应急条件下对散在个体健康查体时可用QBC Star血常规分析仪,批量个体的集中体检则选用Sysmex XP-100。

Objective Both QBC Star and Sysmex XP-100 hematology analyzers are convenient to carry,which can be used normally 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 methods（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 5minutes to complete a blood sample analysis with QBC Star,while about 1min 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 analyzer can be used for the batch medical examination.
