Sysmex XE2100血液分析仪异常报警信息在门诊患者中的应用评价

目的探讨全自动五分类Sysmex XE2100血液分析仪应用于门诊患者的筛查效果。方法对1 000例门诊患者的血液标本同时用Sysmex XE2100血液分析仪分析及显微镜复检,评价其报警系统的性能,并对出现解释性(IP)信息的标本进行分析,同时调查患者就诊科室的分布情况。结果 1 000例门诊患者血标本出现IP信息的比例为12.0%,白细胞分类报警系统的特异性为98.9%,灵敏度为100.0%,阳性预测值85.5%,阴性预测值100.0%,总有效率99.0%。红细胞假阳性率9.0%,以红细胞碎片及缺铁性贫血多见,血小板假阳性率16.0%,以聚集多见。出现IP信息的标本主要来源于急诊科、妇产科、呼吸科、体检中心、儿科。结论五分类血液分析仪在门诊进行血常规分析,覆盖面广,可以起到很好的筛检作用,可提高工作质量和效率。

Application of abnormal warning information of Sysmex XE-2100 hematology analyzer in outpatients

Objective To evaluate the screening significance of Sysmex XE-2100 hematology analyzer in outpa- tients. Methods 1000 blood samples of outpatients were tested by Sysmex XE-2100 analyzer and microscope. The performance of the warning system of XE-2100 analyzer was evaluate and samples with IP information were ana- lyzed. Results 12.0% blood samples were with IP information. For the while blood cell differential count, the speci- ficity was 98. 9%, sensitivity was 100.0%, positive indication value was 85. 5%, negative indication value was 100.0% and the total diagnostic efficiency was 99.0%. For red blood cell, the false positive rate was 9.0%. For platelet, the false positive rate was 16.0 %. The blood samples with IP information were mainly from Department of Obstetrics, Emergency Department, Medical Examination Center, Pediatrics and Respiration. Conclusion Usage of five differential hematology analvzer in outpatients could improve the screening quality and efficiency.
