随着医学科学的迅速发展,国内外已建立了灵敏的血清学检测技术,可检测与甲型和乙型肝炎感染相关的抗原和抗体,对甲型、乙型、非甲非乙型肝炎的诊断有一定的意义。在献血员中进行乙型肝炎表面抗原的检测,虽对控制输血后肝炎取得一些效果,但其意义仍尚难衡量,因为在某些地区似乎仅降低约30%。由于输血后肝炎病情轻或呈亚临床性质,许多 With the rapid development of medical science, sensitive serological detection techniques have been established both at home and abroad, which can detect antigens and antibodies associated with hepatitis A and B infection. For hepatitis A, B, and non-B hepatitis Diagnosis has a certain meaning. The detection of hepatitis B surface antigen among blood donors has some effect on controlling post-transfusion hepatitis, but its significance is still difficult to measure, as it appears to be only a reduction of about 30% in some areas. Due to post-transfusion hepatitis, mild or subclinical, many
