摘　　要：目的为预防医院感染和提高输血安全性,评估乙型肝炎病毒DNA和血清标志物联合检测的价值。方法采用免疫吸附试验(ELISA)和荧光定量PCR技术分别对医院患者和献血员的标本进行乙型肝炎病毒血清标志物和DNA含量检测。结果经ELISA法检测,346例医院患者中乙型肝炎病毒标志物阴性62份,其中呈HBV DNA阳性1例(1.6%);在300份初筛合格的献血员标本中,6例呈HBV DNA阳性(2%),其中222份ELISA法全阴性的标本检出HBV DAN阳性2例(0.9%)。结论本地区人群存在HBsAg阴性的HBV感染;乙型肝炎病毒DNA和血清标志物的联合检测,对预防医院感染和提高输血安全性有重要意义。OBJECTIVE To prevent nosocomial infection and increase the safety of blood supply so as to evaluate the feasibility of routine detections in screening blood donations for HBV DNA and HBV markers. METHODS Three hundred blood donors and 346 cases were detected by ELISA for HBV markers, and then performed by LightCycler for HBV DNA. RESULTS One （1.6%） of 62 negative samples of HBV markers in 346 cases was positive for HBV DNA. Out of 300 qualified donors in screening tests,six （2%） were positive for HBV DNA. And two （0. 9 %） of 222 negative samples of HBV markers were positive for HBV DNA. CONCLUSIONS This study shows that there are HBV infections with negative hepatitis B surface antigen（HBsAg） in population of Qingdao area and that incorporating fluorescence quantitative PCR into ELISA in screening blood donations for HBV infection will further increase the safety of blood supply and prevent nosocomial infections.
