摘要:

目的 评价CellaVision DM96自动化数字图像分析系统(简称DM96)对异常红细胞形态分类的敏感性和特异性。方法 500份乙二胺四乙酸二钾抗凝外周血仪器制片染色后,分别作显微镜检查和DM96白细胞分类计数及红细胞形态分析,以人工显微镜检查结果为标准,比较DM96异常红细胞形态预分类结果的敏感性和特异性。结果 人工显微镜检查发现12种异常红细胞形态。DM96红细胞形态预分类结果的总准确性为94.9%,敏感性随异常红细胞类型而异(23.1%~89.7%),仪器识别各类型异常红细胞形态的特异性和一致性较高(均>90%)。结论 DM96对异常红细胞形态分类有较好的临床应用价值,但必要时需作人工复检。

Abstract:

Objective To evaluate the performance of CellaVision DM96 automated image analysis system for determining red blood cell morphological abnormalities. Methods A total of 500 ethylenediaminetetraacetic acid-K2anticoagulated peripheral blood samples were made into blood smears and stained,and they were determined by DM96 and manual microscopy. The results of manual microscopies were as standard. The sensitivity and specificity of DM96 were evaluated. Results By manual microscopy,there were 12 kinds of red blood cell morphological abnormalities. The overall accuracy of DM96 was 94.9%. The sensitivities ranged from 23.1% to 89.7% according to different kinds of red blood cell morphological abnormalities,while the specificity and consistency were >90% for all red blood cell morphological abnormalities. Conclusions CellaVision DM96 automated image analysis system plays a role in identifying red blood cell morphological abnormalities. However,positive samples should be verified by manual microscopy.
