BC-5500与SYSMEX XS-800i血液分析仪性能评价

目的：评价BC-5500与SYSMEX XS-800i全自动血细胞分析仪性能，以保证不同仪器测定结果的准确性和一致性。方法：按照国际血液学标准化委员会（ICSH）有关规定，对BC-5500和SYSMEX 800i全自动血细胞分析仪从精密度、携带污染率、线性、及ABX-120全自动血细胞分析仪相关性及白细胞分类准确性等方面进行评价。结果：BC-5500及SYSMEX 800i的批间、批内精密度及总精密度变异系数（CV％）均在可接受范围内；各分析参数的携带污染率均〈1．0％；与ABX-120对比分析，各项参数相关性良好；白细胞分类准确性符合要求。结论：BC-5500及SYSMEX 800i血液分析仪性能良好，检测结果准确可靠，在临床应用中可以互换。

The Evaluation of Performance of BC- 5500 Plus and SYSMEX XS - 800i Blood Cells Analyzer

Objective： To evaluate the main performance of BC - 5500 plus and SYSMEX XS - 800i automatic blood cells analyzer, to ensure the two instrument the veracity of test results and consistency. Methods ：According to international hematology standardization commission （ICSH） with the related regulations, the performances of BC -5500 and SYSMEX XS -800i hematology analyzer were evaluated in regards regard to precision, carry - over rate, lineality, thecorrelation between the ABX -120 Heamatology analyzer in detectin results and the accuracy of WBC classification. Results： The CV value of with - and between - Batch precision and that of the total precision of BC - 5500 and SYSMEX 800i were all within the designed range. The carry - over rate was lower than 1.0%. The correlation between ABX - 120 was satisfactory. The accuracy of WBC classification meets the require- ment. Conclusions： The performances of MINRAY BC - 5500 and SYSMEX XS - 800i hematology an- alyzer have proved to be accurate and reliable in test results.
