尽管无法检测到HBV DNA或病毒载量降低是好消息,但这并不意味着可以保证患者已经没有或不会出现肝损伤。毕竟,乙型肝炎病毒是一种棘手的病毒。 【参考文献】 [1]Diagnosed With Chronic Hepatitis B? What Does Your HBV DNA Test Tell You? HepB Blog. 2016....
解析 HBV-DNA斑点杂交试验(-hybridizationtest)在被检查患者血清 中加抗-HBs后离心之沉淀物点在硝酸纤维素膜上使之成为斑点,然后与核酸探针进行杂交反应,若存在同源碱基互补,经放射自显影或酶底物反应即可呈现斑点(显影或显色)为阳性,本法简便、特异性和灵敏性高,可用于大量标本的检测。
Finally, the results of the HBV DNA test are reported. The viral load is typically expressed as a number of copies per milliliter (copies/mL) or as an international unit per milliliter (IU/mL). The results can help determine the stage of the infection, monitor the effectiveness of treatme...
