目的 将全自动血细胞分析仪联合血涂片细胞形态学检查应用在血常规检验中并分析联合检验的价值。方法 在2019年1月至2021年8月我院检验科当中进行常规检验的血常规检验标本当中抽取1000份血液样本作为本文的调查对象，对所有的抽取血液样本均常规进行血涂片检验，并同时开展全自动血细胞分析仪检测，总结2种检验方法联合在一起所发挥的检验作用。结果 ①1000份血液样本中经过复检，存在异常血液样本（阳性）992份，而经过血涂片检出异常样本971份，全自动血细胞分析仪检出异常样本966份，血涂片联合全自动血细胞分析仪“,”Objective The automatic blood cell analyzer combined with the cytomorphological examination of blood smear was applied in the routine blood test and the value of the combined test was analyzed.Methods From January 2019 to August 2021，1 000 blood samples were drawn from the routine blood test specimens for routine testing in the laboratory of our hospital as the investigation objects of this article.At the same time，the automatic blood cell analyzer test was carried out，and the test function played by the combination of the two test methods was summarized.Results(1)Among the 1，000 blood samples that were re-examined，there were 992 abnormal blood samples(positive)，while 971 abnormal samples were detected by blood smear，966 abnormal samples were detected by automatic blood cell analyzer，and blood smear combined with automatic blood cell The analyzer detected 990 abnormal samples，and there was no difference with the re-examination results(P＞0.05).(2)The automatic blood cell analysis combined with the blood smear cytomorphological test in terms of negative predictive value，specificity，Youden index，and misdiagnosis rate of the two methods was significantly better than that of the two methods alone，and the difference was statistically significant(P＜0.05).There was no statistically significant difference(P＞0.05).(3)The positive rate and re-examination results of neutrophils，lymphocytes，eosinophils，monocytes and basophils in blood routine samples detected by automatic blood cell analyzer The consistency of the blood smear test was the lowest，the consistency of the blood smear test was the second，and the consistency of the combined test was the highest，and the difference was statistically significant(P＜0.05).Conclusion The application of automatic blood cell analyzer combined with blood smear cell type blood test in blood routine test can improve the quality of the test，and can provide scientific reference for the diagnosis and treatment of clinically related diseases.
