摘要:

目的评价SYSMEX XN-3000血液分析仪(简称XN-3000)计数外周血有核红细胞(NRBC)的方法学特性和临床应用价值。方法分别用XN-3000与人工显微镜镜检法对96例血液标本进行检测,采用SPSS 11.0统计软件分析其相关性。结果XN-3000检测NRBC的敏感性为98.41%,特异性为93.94%,假阳性率为3.13%,假阴性率为3.13%,检测结果重复性好,低值变异系数(CV)为6.5%,中、高值CV均<5%。与显微镜镜检法计数外周血中NRBC数量有极好的相关性(r2>0.867),且两者差异无统计学意义(P=0.019)。结论使用XN-3000进行外周血NRBC计数,方法可靠,操作简便快速,准确性高,可替代显微镜法,有一定的临床应用价值。

Abstract:

Objective To evaluate the methodology characteristics and clinical application significance of SYSMEX XN-3000 automatic blood cell analyzer(XN-3000) for the determination of peripheral blood nucleated red blood cell (NRBC). MethodsBy XN-3000 and manulal microscopy, 96 blood specimens were determined, and the correlation was analyzed by SPSS 11.0 statistical software. ResultsBy XN-3000, the sensitivity was 98.41%, the specificity was 93.94%, the false positive rate was 3.13%, and the false negative rate was 3.13%. The repeatability was good, the low coefficient of variation (CV) was 6.5%, and the middle and high CV were <5%. There was a good correlation for NRBC and manual microscopy (r2>0.867). Comparison of 2 methods showed no statistical significance (P=0.019). ConclusionsUsing XN-3000 for peripheral blood NRBC is reliable, simple and rapid with high accuracy, which can take the place of microscopy, and has certain clinical application significance.
