改进血常规单纯以血细胞计数结果作为自动审核的规则，以提高检验报告的正确率。

设定3种血常规自审规则，以单纯血细胞计数结果为自审规则A、以血细胞计数结果和血细胞散点图异常报警信息为自审规则B、以血细胞计数结果和血细胞散点图异常报警信息及临床初步诊断为自审规则C。对山东省泰安市中心医院检验科2017年2月份10 000份血常规标本分别按3种自审规则进行审核，比较3种自审规则的标本周转时间(turn around time, TAT)、假阳性率和假阴性率。

改进的自审规则C的TAT为16.6 min，与自审规则A的TAT(15.9 min)比较，差异无统计学意义(q=2.11，P>0.05)，而自审规则C与自审规则A相比，假阳性率由8.23%(706/8580份)减少到5.96%(706/8580份)，且差异有统计学意义(χ²=4.89，P<0.05)，假阴性率由3.94%(56/1420份)减少到1.91%(27/1420份)，差异亦有统计学意义(χ²=5.68，P<0.05)。自审规则B与自审规则A比较，假阳性率由8.23%减少到7.46%，假阴性率由3.94%减少到2.89%，而差异均无统计学意义(χ²值分别为0.41、1.07，P均>0.05)。自审规则C审核一致性为94.62%，均高于自审规则A(92.38%)和自审规则B(93.19%)；改进后的自审规则C，可检出部分血象几乎正常，但存在血液系统寄生虫或血液系统疾病的结果。

通过增加血细胞散点图异常报警信息和临床初步诊断的血常规自审规则的改进，降低了检验报告的假阳性率和假阴性率，提高了检验结果的准确性和检验报告的质量。

To increase the accuracy of routine blood test report by improving the auto-verifying system.

Three auto-verifying rules of blood routine examination were established. The rule A contains pure blood count results, the rule B contains pure blood count results and blood cells scatterplot abnormal alarm information, and the rule C contains blood count results, blood cells scatterplot abnormal alarm information and clinical preliminary diagnosis information. Ten thousand blood specimens were verified by the three self-verifying rules, respectively. The turn around time (TAT), false positive rates and false negative rates were compared.

There were no significant differences between the rules C and the rules A in TAT time (16.6 min vs 15.9 min, q=2.11, P>0.05). However, compared with rules A, the rules C lead to significantly reduction of the false positive rates (8.23% vs 5.96% χ²=4.89, P<0.05), and significantly reduction of the false negative rates (3.94% vs 1.91% χ²=5.68, P<0.05). Meanwhile, there were no significantly different false positive rates between the rules C and the rules B (8.23% vs 7.46%, χ²=0.41, P>0.05), as well as significantly different false negative rates (3.94% vs 2.89%, χ²=1.07, P>0.05). The audit consistency of the rules C was 94.62%, and was higher than that of the rules A (92.38%) and the rules B (93.19%). The improved rules C could detect parasites or malignant hematopathy in the blood but the hemogram of which was almost normal.

The improved auto-verifying system increased the accuracy of the test results and ensured the quality of the report.
