目的评价贝克曼库尔特LH750血细胞分析仪(LH750仪)的应用性能。方法按照国际血液学标准化委员会(ICSH)公布的评价方法,结合实验室仪器性能验证流程对LH750仪的精密度、携带污染率、线性范围、准确度、可比性等进行测定,并将其与XT-1800i血细胞分析仪(XT-1800i仪)进行对比。结果 LH750仪测定主要项目精密度CV值为0.93%~3.86%;总重复性CV值为0.61%~2.66%;携带污染率为0.00%~0.93%;准确度偏倚为0.80%~1.61%,分别两两t检验,差异无统计学意义(P>0.05);线性测定r值为0.996~0.999;对比检测结果,差异无统计学意义(P>0.05)。结论 LH750仪测定主要参数各项性能指标均在其要求范围,能满足临床诊治患者。
Objective To evaluate the performance of Beckman Coulter LH750 hematology analyzer (LH750). Methods According to the evaluation method published by the International Commission of Hematology Standardization (ICSH), the precision, carrying rate, linear range, accuracy and comparability of the LH750 instrument were measured and compared with the XT -1800i hematology analyzer (XT-1800i instrument) for comparison. Results The precision of LH750 was 0.93% ~ 3.86%. The total CV was 0.61% ~ 2.66%. The carrying rate was 0.00% ~ 0.93%. The accuracy was 0.80% -1.61% There was no significant difference between two groups (P> 0.05). The linear r value was 0.996-0.999. There was no significant difference between the two groups (P> 0.05). Conclusion LH750 instrument to determine the main parameters of the performance indicators are in its scope, to meet the clinical diagnosis and treatment of patients.
