血清中有乙型肝炎表面抗原(HBsAg)的存在。表明其被乙型肝炎病毒感染,也表示活病毒继续影响宿主的肝细胞复制 HBsAg。抗原血症目前认为可能是有传播危险的最有效的指标。抗原血症同样说明肝脏存在着疾病。持续性抗原血症伴有肝脏疾患这是常见的,也可见于部分献血者。乙型肝炎住院病人中,抗原血症很少有持续3个月以上的。但 Nielsen 等从112例中发现有11例(9.8%)持续13周后出现急性肝炎症状。且11例病人在6个月时均有 HBsAg 存在。Red(?)ker从429例急性黄疸型乙型肝炎随访观察1～5年发现有10%的病人持续有 HBsAg。一个无 HBsAg 抗体
Serum hepatitis B surface antigen (HBsAg) exists. Indicating that it is infected with the Hepatitis B virus, also indicates that the live virus continues to affect the host’s hepatocyte replication HBsAg. Antigenemia is currently considered the most effective indicator of risk of transmission. Antigenemia also shows the existence of liver disease. Persistent antigenemia associated with liver disease This is common, but also found in some blood donors. Inpatients with hepatitis B, anti-hyperlipoproteinemia rarely last more than 3 months. However, Nielsen et al. Found that 112 (9.8%) of 112 patients developed acute hepatitis symptoms after 13 weeks. And 11 patients had HBsAg at 6 months. Red (?) Ker from 429 cases of acute jaundice hepatitis B follow-up observation of 1 to 5 years found that 10% of patients with persistent HBsAg. One without HBsAg antibody
