摘　　要：目的分析疟原虫病例血常规异常散点图特点,提高疟原虫检出率。方法采用Sysmex XE-2100全自动血液分析仪对本院发热患者进行血常规检测,DIFF散点图异常并符合复片标准规则的血样,进一步涂片染色显微镜镜检。结果经镜下检查确诊1例疟原虫感染病例,白细胞DIFF散点图显示单核细胞上方出现弥散细胞团,嗜酸性粒细胞比例增加且与中性粒细胞的间距减小,细胞碎片增多。经薄血膜推片瑞氏-吉姆萨染色发现疟原虫环状体和裂殖体。结论发热患者血常规DIFF散点图出现特征性异常改变时,需及时涂片镜检筛查疟原虫。Objective To analyze the abnormal characteristics of blood routine scatter plots of Plasmodium spp.cases and improve the detection rate.Methods Sysmex XE-2100 automatic blood analyzer was used to detect the blood routine of a patient with fever in liaohe Oilfield gem flower hospital.The blood samples with abnormal DIFF scatter plot would be conformed by the standard rules for reexamination and further observation under the microscope with smear staining.Results The DIFF scatter diagram of leukocytes showed diffuse cells appeared above monocytes.The proportion of eosinophils increased,the distance between eosinophil and neutrophils decreased,and the cell debris increased.The rings and schizonts of Plasmodium spp.were found by Wright-Gimsa staining on thin blood film.Conclusion In the case of the blood routine DIFF scatter plot of the fever patient presented characteristic abnormalities,smear microscopy should be performed to screen for Plasmodium.
