XE-2100全自动血细胞分析仪检测有核红细胞的评估

Evaluation on nucleated red blood cell detection by XE-2100 automatic blood cell cytoanalyze

目的：对Sysmex XE-2100全自动血细胞分析仪检测有核红细胞的性能进行评估。方法：以XE-2100血细胞分析仪测定含有有核红细胞的标本观察其重复性，线性范围，携带污染率，结果的稳定性及与手工法的比较。结果：XE-2100血液分析仪测定有核红细胞的重复性好，有核红细胞在（0-33．1）×10^9／L范围内线性良好，在室温条件下有核红细胞数值在48h内变化差异无显著性，携带污染率较低，与显微镜计数结果之间有良好的相关性（r=0．967）。结论：XE-2100血液分析仪测定有核红细胞具有快速，客观，结果较准确，精密度高等特点，适合临床检测有核红细胞。

Objective： To evaluate the performance of sysmex XE- 2100 automatic blood cell cytoanaiyze on nucleatod red blood cell detection. Methods：To observe the reproducibility,linear range, carry over rate of XE -2100 automatic blood cell cytoanalyze on nucleated red blood cell detection, and compare with handmethods. Results：This method has a fine reproducibility, and a fine linear range （0 - 33. 1 × 10^9/L）, under room temperature the results have no significance difference within 48 hours. Carry over rate was lower than hand method, and had good correlation with microscope counted number（ r =0. 967 ）. Conclusion：The methods of XE-2100 automatic blood cell cytoanalyze detection on nucleated red blood cell was quick, objective, accurate and high precision which is suitable for clinical detection on nucleated red blood cell .
