摘要
目的利用瑞美检验网络管理系统（LIS）制定SysmexXT2000全自动血液分析仪血涂片显微镜复检标准，保证血液分析仪结果的准确性。方法根据“41条复检规则”，利用瑞美检验网络管理系统对11720例血常规结果进行数据分析，制定血涂片复检标准，通过对4320例结果分析评价标准的可行性和应用性。结果LIS可自动筛选需要涂片复检的阳性血常规结果，复检标准与显微镜镜检阳性评价结果为：真阳性率20．11％、假阳性率4．24％、真阴性率72．66％、假阴性率2．99％。结论LIS系统血涂片复检标准的制定节约了人工判断的时间，避免了人为因素引起的判断错误和遗漏，保证了血常规检查的准确性。2．99％的假阴性率符合国际血液学复审协作组关于假阴性低于5．0％的规定。
Objective To establish the standard of slide smear review criteria for Sysmex XT2000 Automated Heamatology Analyzer with LIS,and ensure the analytic results exactly. Methods Based on 41 review rules,the construction of the standard of review was estimated by data analysis of 11 720 blood samples with anticoagulation of EDTA-Kz,and the statisties on the data of 4 320 samples were made to find out the reliablitity of the standard. Results LIS could choose the results that need slide smear review,the evaluational results of review criteria and microscopic examination were the true positive rate 20. 11% ,false positive rate 4.24% ,true negative rate 72.66% and false negative rate 2.99%. Conclusion To establish the standard of slide smear review criteria with LIS could save the human judgement time,avoid human-induced errors and ommissions,and could insure the accuracy of blood analysis. 2.99% of false negative rate was less than 5%, which was consistent with the criteria instituted by International Society for Laboratory Hematology.
