全自动血细胞分析仪与血细胞形态学检验在血常规检验中的应用价值

目的比较全自动血细胞分析仪和血细胞形态学检验在血常规检验中的应用价值。方法选择2019年6月至2019年7月在本院进行血常规检验的3 000例患者为研究对象,将所有患者的样本均分为A、B两份,分别采用全自动血细胞分析仪和全自动血细胞形态学数字图像分析仪检查。以人工显微镜检查结果作为金标准,比较两种检验方式的白细胞异常检测结果。结果 A组检测结果显示,3 000例患者样本的阳性率为3.67%,灵敏度为90.99%,特异度为99.69%;B组检测结果显示,3 000例患者样本的阳性率为3.67%,灵敏度为97.30%,特异度为99.93%。B组检测的灵敏度高于A组(P<0.05)。结论全自动血细胞形态学数字图像分析仪在白细胞异常检测中的灵敏度高于全自动血细胞分析仪,具有效率高、速度快的优势,但仍不能替代人工镜检。

Application value of automatic blood cell analyzer and blood cell morphology examination in routine blood test

Objective To compare the application value of automatic blood cell analyzer and blood cell morphology examination in blood routine test. Methods From June 2019 to July 2019, 3 000 patients who underwent routine blood test in our hospital were selected as the study subjects. The blood samples of all patients were divided equally into group A and B,and were examined by automatic blood cell analyzer and automatic blood cell morphology digital image analyzer respectively.The result of artificial microscope was taken as the gold standard, and the results of leukocyte abnormality detection in the two methods were compared. Results The results of the group A showed that the positive rate of samples in 3 000 patients was 3.67%, the sensitivity was 90.99%, and the specificity was 99.69%;the results of the group B showed that the positive rate of samples in 3 000 patients was 3.67%, the sensitivity was 97.30%, and the specificity was 99.93%. The sensitivity in the group B was higher than that in the group A(P<0.05). Conclusion The automatic blood cell morphology digital image analyzer in the detection of leukocyte abnormalities has higher sensitivity than the automatic blood cell analyzer, it has the advantages of high efficiency and fast speed, but which can not replace the artificial microscopy.
