采用酶联免疫法（ELISA）对270例慢性肝病和对照组103例非肝病患者进行了HBV标志物及抗－HCV的检测。结果显示；慢性肝病HBV感染率为85．2％，抗－HCV阳性率为23．7％，HBV和HCV双重感染率为17．8％，单纯抗－HCV阳性率为5．9％。对照组HBV感染率为14．6％，抗－HCV阳性率为5．8％。126例有输血史的慢性肝病患者抗－HCV阳性率（42．1％）明显高于144倒无输血史者（7．6％），两组差异有显著性（P＜0．01）。提示HBV感染是引起慢性肝病的主要病因，HCV次之。HCV感染与输血有密切关系。
Enzyme-linked immunosorbent assay (ELISA) was used to detect HBV markers and anti-HCV in 270 cases of chronic liver disease and 103 cases of non-liver disease in the control group. The results showed that the infection rate of chronic hepatitis was 85.2%, the positive rate of anti-HCV was 23.7%, the double infection rate of HBV and HCV was 17.8%, the positive rate of anti-HCV was only 5.9%. The control group HBV infection rate was 14.6%, anti-HCV positive rate was 5.8%. The positive rate of anti-HCV (126.1%) in 126 cases of chronic liver disease with blood transfusion was significantly higher than that of 144 cases without blood transfusion (7.6%). There was significant difference between the two groups (P <0.01). Prompt HBV infection is the main cause of chronic liver disease, HCV second. HCV infection and blood transfusions are closely related.
