Tóm tắt Tiếng Anh Hepatitis causing by hepatitis C virus is the dangerous and difficult treatable disease, left the heavy consequences to the patients, and there isn't the available vaccine. Therefore, the determination, qualification, as well as typing of HCV are the necessary parameters to meet the requirement of physicians while they select the most propriety regime to treat and follow up the infected patients. In this study, we have carried out the immunoassay to detect anti HCV and serotype of HCV from patients'sera; performed the molecular biology assay to detect HCV-RNA (using RT-PCR target the 5'UT region of viral genome), and to quantify the HCV in the patients' blood (using bDNA). The received results have demonstrated that 70% HCV-RNA(+) among 319 cases with anti HCV(+). With 169 cases that have been done the serotyping, the most common serotypes detected are type 6 (44.6%) and type 1(37.3%). Type 1 is referred as the most difficult to response to the specific treatment. From the quantitative assay, the results have also received that type 1 and type 6 infected patients with high quantity of viremia. From this study, the role of the molecular biology assays are defined as the very necessary laboratory tool to help physicians in diagnostic as well as treatment of patients with HCV infection.
