乙型肝炎病毒(HBV)核酸扩增检测(NAAT)对HBV感染的诊断和治疗非常重要。研究人员在cobas 4800系统上评估cobas HBV NAAT(Roche Diagnostics GmbH,Mannheim,Germany)的分析性能,并与COBAS AmpliPrep / COBAS TaqMan HBV Test(CAP / CTM HBV)进行比较。 研究人员使用三种水平的co

乙型肝炎病毒(HBV)核酸扩增检测(NAAT)对HBV感染的诊断和治疗非常重要。研究人员在cobas 4800系统上评估cobas HBV NAAT(Roche Diagnostics GmbH,Mannheim,Germany)的分析性能,并与COBAS AmpliPrep / COBAS TaqMan HBV Test(CAP / CTM HBV)进行比较。 研究人员使用三种水平的cobas HBV / HCV / HIV-1对照试剂盒评估,并使用临床样品在7个水平评估整个预期测量范围(10.0-1.0×10 9 IU / mL)的线性关系。采用第4版WHO国际HBV标准(NIBSC代码:10/266)对检测能力进行了验证,包括空白限度(LOB),检测限(LOD)和定量限(LOQ)。使用205个临床样品(102个血清和103个EDTA血浆)比较两个系统之间的相关性。 结果显示,重复性和总体不精密度(变异系数)的范围分别为0.5%至3.8%和0.5%至3.5%。线性关系(决定系数R 2)为0.999。在观察到的比例率(85%)内,LOB,LOD和LOQ均可接受。在血清和血浆样品间两个
