摘　　要：目的:评估ABX Pentra DF 120血细胞分析仪对有核红细胞(NRBC)提示的可信度。方法:采集血细胞仪器白细胞分类栏有NRBC报警提示的样本170份及430份无NRBC报警提示的样本涂片进行镜检,并对其检测结果进行比较。结果:ABX Pentra DF 120全自动血细胞分析仪对NRBC报警提示的灵敏度为90.7%,特异度为93.2%,阳性预期值为76.47%,阴性预期值为96.28%,假阳性率为23.53%。结论:ABX Pentra DF 120血细胞分析仪对NRBC报警提示具有一定可信度,但其假阳性较高,因而该血细胞分析仪对NRBC报警提示仅可作为一种过筛作用,样本仍需显微镜检查。Objective：To evaluation the credibility of system ABX Pentra DF 120 Hematology Analyzer in detection of nucleated red blood cells （NRBC）. Methods： Collected 170 cases spcimens with abnormal prompt about NRBC in WBC column and 430 cases spcimens without abnormal prompt for smear test and compared. Results：The sensitivity of ABX Pentra DF 120 Hematology Analyzer to NRBC was 90.7%, specificity was 93.2%,positive predictive value was 76.47%, negative predictive value was 96.28%,false positive rate was 23.53%. Conclusion：The alarm to NRBC from system ABX Pentra DF 120 Analyzer has a certain credibility, the false positive rate is also higher, so abnormal prompt to NRBC from ABX Pentra DF 120 Hematology Analyzer could be used as an effective screening tool, but also could not completely replace the microscope detection.
