摘　　要：目的制定科学合理的血液复栓规则并对其进行评价。方法以国际血液学41条复捡规则为参考，结合Beck—man-coulterAC．T5diff血液分析仪的-测试性能及报警系统，自定复检规则。对1400例门诊和住院病人的标本进行全自动血细胞分析并同时涂片镜检，观察细胞数量和形态学变化。比较二者结果，对各务自定复检规则进行统计学分析。结果各条规则中假阳性率最高的是异常淋巴细胞，其次是巨大不成熟细胞及单核细胞。真阳性率最高的是粒细胞相对计数。自定复检规则形态学评估真阳性率12．3％，假阳性率2．7％，真阴性率83．O％，假阴性率2．0％。结论制定适合Beck—man-coulter AC．T 5diff血液分析仪的15条复检规则，照此执行，既可保证工作质量又提高工作效率，为临床提供更具参考价值的信息。Objective To establish the microscope review criteria for the Beckman-coulter AC. T 5diff hematology analyzer. Methods Totally 1 400 blood samples were tested by using the Bckman-coulter AC. T 5diff hematology analyzer and smeared for microscopic examination. True positive rate, false positive rate, true negative rate and false negative rate were e- valuated and calculated according to the 41 rules suggested by the International Consensus Group for hematology review as well as the particular alarm system of the Beckman-coulter AC. T 5diff hematology analyzer. Results The most cases show- ing false positive rate were abnormal lymphocytes, large immature cells and monocytes. The most case showing true positive rate was relative granulocyte count. Microscopic examination results：true positive rate, false positive rate, true negative rate and false negative rate were respectively 12.30//00,2.70//00,83. 0% and 2.0%, respectively. Conclusion Establishment of rea- sonable microscope review criteria is beneficial to improving work efficiency, reducing probability of missed diagnosis and providing more useful information for clinical.
