Molecular and Serological Detection of Hepatitis B and C Viruses: Molecular and seroepidemiological

PCR should be introduced to screen blood donors negative by ELISA test to be sure that their blood is not infectious. Polymerase chain reaction will be suitable to monitor viral replication in spontaneous course and treated patients. In order to avoid unnecessary risk of HBV infection, patients who depend on recurrent transfusion should be vaccinated . Blood donors must be tested for HBsAg before transfusion to recipient. Haemodialysis patients positive to HBsAg, must have separate machine. Surgical and tattooing instruments must be well sterilized before each operation. Isolation of patients positive for HBV DNA could be beneficial for preventing the dissemination of HBV among haemodialysis patients. HBsAg carriers should be prohibited from donating blood for transfused. persons with antigen-positive hepatitis B should be considered infectious and control measures by taken with respect to potentially infectious material, such as blood and blood-contaminated secretions and body secretions.
