目的:对Sysmex XT-2000iv型动物血细胞分析仪进行性能验证。方法:对该仪器的准确度、精密度、携带污染率和线性进行验证,并与其他仪器测定结果及人工白细胞分类镜检结果进行比较。结果与结论:该仪器的准确度、精密度、携带污染率和线性均在允许范围内;与JT-IR血细胞计数仪测定结果相关性良好;白细胞分类测定结果与人工显微镜分类比较,中性粒细胞、淋巴细胞和嗜酸性粒细胞相关性较好,单核细胞和嗜碱性粒细胞相关性较差。Sysmex XT-2000iv动物血细胞分析仪各方面性能良好,测定结果准确可靠,可以满足GLP安全性评价课题动物血液样本分析的需要。
Objective: To verify the performance of Sysmex XT-2000iv animal hematology analyzer. Methods: The accuracy, precision, carrying rate and linearity of the instrument were verified, and compared with the results of other instruments and the classification results of artificial leukocyte. RESULTS AND CONCLUSION: The accuracy, precision, carrying rate and linearity of the instrument were all within the allowable range. The results were in good agreement with the results of JT-IR hemocytometer. The results of leukocyte classification were compared with those of artificial microscope. Correlation of cells, lymphocytes and eosinophils is better, and the correlation between monocytes and basophils is poor. Sysmex XT-2000iv animal hematology analyzer has good performance in all aspects, the measurement results are accurate and reliable, which can meet the needs of animal blood sample analysis of GLP safety evaluation subject.
