CLIN CHEM LAB MED:多中心对Alinity hq血液分析仪性能评价

Alinity hq (Abbott)是一款新型高通量血液分析仪,通过采用光学原理对血细胞进行检测和计数。该仪器报告了29个参数,包括六部分的白细胞(WBC)差异。这项多中心研究的目的是评估Alinity hq的分析和临床表现。

Alinity hq (Abbott)是一款新型高通量血液分析仪,通过采用光学原理对血细胞进行检测和计数。该仪器报告了29个参数,包括六部分的白细胞(WBC)差异。这项多中心研究的目的是评估Alinity hq的分析和临床表现。

研究人员对全血计数(CBC)结果和形态学标记与CELL-DYN Sapphire (Abbott)结果和2×200细胞手工鉴别结果进行了比较,这些结果来自荷兰三个不同临床实验室的明确定义的患者群体的1473个全血样本。此外,还评估了运行内和实验室内的精度、线性、定量限度、结转和样品稳定性。对外部质量评估样本也进行了评估。

数据分析表明,除了嗜碱性粒细胞外,所有CBC参数的碱度hq结果与CELL-DYN蓝宝石的结果具有很好的一致性。Alinity hq WBC的鉴别结果与手工鉴别结果的一致性较高,与CELL-DYN Sapphire相比,与手工碱基结果的一致性较好。Alinity hq Blast flag的敏感度为57.6%,与CELL-DYN SapphireBlast Alert的敏感度为57.6%。当考虑≥5%的样本时,Alinity hq Blast flag的灵敏度为70.0%。分析结果表明,碱度总部的性能与最先进(SOTA)的性能特征一致。

因此,Alinity hq的分析和临床性能特点使其非常适合临床实验室使用。
