两种全自动血细胞分析仪报警信息功效率的比较

目的评价Sysmex XE-5000全自动血细胞分析仪（简称XE-5000）和Sysmex XS-1000i全自动血细胞分析仪（简称XS-1000i）报警信息的功效率,证明XE-5000在常规血细胞检验中可提高实验室的工作效率。方法对1 028份全血标本分别采用XE-5000、XS-1000i和显微镜镜检进行形态学特征分析,以镜检作为形态学定性金标准,采用配对资料χ2检验对前两组结果进行统计学分析。结果 XS-1000i原始细胞报警有23个假阳性、3个真阳性和1个假阴性;而XE-5000有5个假阳性、3个真阳性和0个假阴性。XS-1000i异型淋巴细胞和异常淋巴细胞的报警有103个假阳性、30个真阳性和0个假阴性;XE-5000有28个假阳性、33个真阳性和0个假阴性。结论XE-5000报警信息的功效率显著高于XS-1000i,可以有效减少实验室镜检复查率,提高实验室的日常工作效率。

Comparison of the efficiency of flags of two kinds of automatic blood cells analyzer

Objective To evaluate efficiency of flagging rates of Sysmex XE-5000and Sysmex XS-1000i.Methods A total of 1 028whole blood samples were detected by for morphological characteristics by using XE-5000,the XS-1000iand microscopic method.Results of the former two methods were compared with microscopic method by using chi-square analysis.Results Of XS-1000i,the blast flag demonstrated 23false positive,3true positive and 1false negative,and of XE-5000,there were 5false positive,3true positive and 0false negative.Of XS-1000i,the abnormal lymphocyte and atypical lymphocyte flag showed 103false positive,30true positive and 0false negative,and of XE-5000,there were 28false positive,33true positive and 0false negative.Conclusion XE-5000might be more efficient than the XS-1000i,which could reduce the review times and improve the efficiency of daily work in laboratory.
