背景 要理解经输血途径传播病毒感染的风险,很重要的一点是正确地评估输血而后发生感染的病例。研究设计与方法 对于1997、1998和1999年期间发生输血后HBV感染的记录进行分析。在当时所有这些输血病例输血前均未将核酸检测技术(NAT)引入供者血液筛选方案中。本项研究所涉及的每一份供者标本均贮存于冰冻状态,为明确病毒性感染,回顾性研究采用了HBV PCR及血清学实验。对于HBV阳性标本另作HBV
Background To understand the risk of transmitting a viral infection by the transfusion route, it is important to correctly assess the transfusion and subsequent infection. Study Design and Methods Analysis of records of post-transfusion HBV infection during 1997, 1998 and 1999. None of the blood transfusions prior to transfusion introduced nucleic acid detection technology (NAT) into the donor blood screening program at that time. Each donor specimen involved in this study was frozen in order to clarify the viral infection. Retrospective studies using HBV PCR and serological tests were performed. HBV-positive specimens for another HBV
