Abstract: Objective To analyze the positive rates of HBV and HCV to provide effective precautionary measures and select low-risk donor. Methods To analyze the positive rates of HBV and HCV from blood donor specimens from 2011 to 2015. Results The positive rates of HBV and HCV declined from 0.9% to 0.6% and from 0.2% to 0.1%,respectively （P<0.05）. No statistical difference was seen of positive rates of HBV and HCV between males and females （P>0.05）. However,the positive rates of HBV and HCV in planned blood donors were higher than in personal blood donors. Conclusions HBV and HCV infections were decreasing in voluntary blood donors. The positive rates of HBV and HCV in planned blood donors were significantly higher than in personal and co-operative blood donors. It is necessary to choose the regular blood donors,and improve sensibility and specificity of detection to ensure blood safety.
