目的：探讨SYSMEX XN-1000全自动血液分析仪（简称XN-1000）计数有核红细胞（NRBC）的准确性。方法应用XN-1000对66例外周血标本进行NRBC检测，同时用流式细胞仪（FCM）和显微镜（镜检法）对同一份外周血的NRBC百分率进行计数。以镜检法为金标准，比较不同方法的计数结果。结果 XN-1000与镜检法检测NRBC有较好的相关性（r＝0．927），但低于FCM与镜检法NRBC的相关性（r＝0．956），XN-1000与FCM检测NRBC的相关性较高（r＝0．994）。XN-1000、FCM计数结果与镜检法的结果间差异均无统计学意义（P＞0．05）。XN-1000检测NRBC％较FCM法有更高的诊断特异性（95．7％）。结论 XN-1000能快速、准确、有效地自动计数外周血NRBC。

Objective To investigate the accuracy of nucleated red blood cell (NRBC)count determined by SYSMEX XN-1000 automatic hematology analyzer(XN-1000).Methods A total of 66 peripheral blood samples were collected and determined for NRBC by XN-1000,and the results of NRBC%were compared with those by flow cytometry (FCM)and manual microscopy for the same sample.The manual microscopy was as golden standard.Results There was a good correlation for NRBC between XN-1000 and microscopy (r =0.927 ),but the correlation was lower than that between FCMand manual microscopy (r=0.956).The correlation between XN-1000 and FCMwas the best (r=0.994). The results of XN-1000 and FCMwith manual microscopy had no statistical significance(P>0.05).XN-1000 for NRBC%had a better specificity (95.7%) than FCM.Conclusions XN-1000 automatic hematology analyzer has good performance for detecting NRBC in peripheral blood rapidly,accurately and effectively.
