输血后肝炎系指输入携带传染因子而得病。但其病原属性如何,过去一直是个迷,通常统称为血清型肝炎,也曾有人提出丙型肝炎病毒可能是该病的病原因子。70年代以来采用对供血员检测 HBsAg 及SGpT 作为筛选标准,要求 HBsAg 阴性和SGpT<40Korman 单位才可输血。无可否认自从用乙型肝炎表面抗原(HBsAg)阴性血以来,输血后肝炎的发病率已经减少。然而尽管采用乙型肝炎表面抗原阴性供血员的血,但受血者发生输血后肝炎的发病率仍然接近10%。日本从1970～1977
Hepatitis after transfusion means getting sick with the infectious agent. However, its pathogenic nature of the past has been a fan, usually collectively referred to as hepatitis, has also been suggested that hepatitis C virus may be the etiological factor of the disease. 70s since the use of blood tests for the detection of HBsAg and SGpT as a screening criteria require HBsAg negative and SGpT <40Korman units can be transfused. Admittedly, the incidence of post-transfusive hepatitis has decreased since hepatitis B surface antigen (HBsAg) -negative blood has been available. However, despite the use of hepatitis B surface antigen-negative blood donor blood, but the blood transfusion in recipients after the incidence of hepatitis is still close to 10%.
