目的：分析全自动血液分析仪检测血常规的临床复检规则,评估其临床意义,提高血细胞分析结果的准确性。方法：根据国际实验血液学学会（ISLH）推荐的41条复检规则并结合本科实际情况,制定了本科血细胞分析仪的17条复检规则。对1492个门诊、住院和健康查体标本进行全血细胞分析,同时用SP-1000i制片、染色、镜检。结果：1492例标本,符合规则307例,复检率为20.57%（307/1492）,真阳性率、假阳性率、真阴性率和假阳性率分别为13.06%（195/1492）、7.51%（112/1492）、77.08%（1150/1492）和2.35%（35/1492）。结论：血细胞分析仪的复检规则有重要的临床意义,能有效地筛选出真正异常样本,提高工作效率,为临床诊治提供有价值的信息。

The blood retest rules and clinical application in HST302

Objective： To analyze the retest rules of blood routine test in full automatic blood analyzer. Assess its clinical significance. Improve the accuracy of analysis results. Methods： Made the retest rules about 17 pieces, combined the 41 retest rules recommended by ISLH with the actual situation in our laboratory. Analyzed the 1 492 blood samples from outpations, inpations and healthy persons. At the same time, smear films and stain them in SP-1000i, and examined them in microscope. Result： In the 1 492 samples, 307 cases conformed to the rules, retesting rate of 20.57% （307/1 492）. The true positive rate, false positive rate, true negative rate and false negative rate was 13.06% （195/1 492）, 7.51% （112/1 492）, 77.08% （1 150/1 492） and 2.35% （35/1 492）. Conclusion： The retest rules in blood analyzer has important clinical significance. It can effectively filter out the ture abnormal samples, impove the work efficiency and provide the valuable information for clinical diagnosis and treatment.
