摘要 目的:观察不同标本处理方法对实时荧光定量聚合酶链反应(PCR-荧光探针法)检测乙型肝炎病毒(HBV)DNA结果的影响。方法:收集本院50例经临床确诊门诊病人血清及产科住院的HBV阳性的乳汁作为检测标本,采用不同处理方法(煮沸法、核酸纯化法、Chelex100树脂法)平行处理后,用PCR-荧光探针法测定HBV-DNA的含量,分析结果。结果:50例乙肝确诊患者标本采用煮沸法、核酸纯化法、Chelex100树脂法处理后定量PCR检测阳性结果分别为24例(48.0%)、50例(100.0%)、26例(52.0%);核酸纯化法处理标本定量检测结果均大于102copy/μL,与其他两种方法定量结果比较,差异具有显著性。结论:核酸纯化法提取标本进行FQ-PCR定量检测HBV-DNA,可保证标本的提取质量,对乙型肝炎的诊治具有重要意义。
