摘　　要：目的:对SysmexXT-2000i血细胞分析仪性能概况和运用进行综合评价。方法:用SysmexXT-2000i和ACTdiff常规检测标本,对结果进行统计学分析。结果:批内和批间精密度,除PLT的CV值为10.8%外,WBC、RBC、Hb的CV值为均小于4.5%;携带污染率均小于1.5%;准确度与定值比较P>0.05;线性,r>0.9998;比较试验,与ACTdiff比较试验中除PLT外,WBC、RBC、Hb的P>0.05;分类,中性粒细胞和淋巴细胞CV<5.8%,与人工分类相关系数r>0.9905,单核细胞、嗜酸性细胞、嗜碱性细胞分类情况较差。结论:SysmexXT-2000i血细胞分仪的批内精密度、批间精密度、携带污染率、准确度、线性、比较试验,除PLT外,其他WBC、RBC、Hb均较好,报告结果准确可靠;分类试验,中性粒细胞、淋巴细胞和嗜酸性细胞与人工分类相关性好,单核细胞、嗜碱性细胞分类与人工分类相关性一般。Objective To evaluate the performance characteristics and the use of Sysmex XT-2000i automated hematology analyzer. Methods Blood samples were routinely detected by the Sysmex XT-2000i along with the ACT diff analyzer. The performance characteristics of the Sysmex XT-2000i were compared with those of the ACT diff and the data was analysed statistically. Results Within-and between-batch precision: the CV value of the WBC, RBC, or Hb was less than 4.5%while the PLT CV was 10.8%; Carry-over rate: less than 1.5%; Accuracy: comparison with the setting value P >0.05; Linearity: r >0.999 8; Comparison test: P was greater than 0.05 in WBC, RBC, or Hb but not in PLT; Classification: The CV of both neutrophil and lymphocyte was less than 5.8%and the manual classification-related coefficient r was greater than 0.990 5, but a relatively poor classification was present in monocyte, eosinophil, and basophil. Conclusion The Sysmex XT-2000i hematology analyzer is better in within-and between-batch precision, carry-over rate, accuracy, linearity, and comparison test for WBC, RBC, and Hb and its analytical results are accurate and reliable; Neutrophil, lymphocyte and eosinophil in the classification test have a good correlation with those in the manual reference method while monocyte and basophil only have a moderate correlation.
