Background: In spite of available, and sensitive screening assay for detection of hepatitis B virus surface antigen (HBsAg), occasional cases of post-transfusion hepatitis B virus infection are still observed. The aim of the present study was to assess the prevalence of positive anti hepatitis B core (anti-HBc) and presence of HBV-DNA in serum sample of healthy blood donors negative for both HB...
background: the outcome of hepatitis b virus (hbv) infection is chronic or resolved hbv infection. over the time, the levels of hbsag or anti-hbs declined and were not detectable in their sera and was named as isolated anti-hbc. the purpose of this study was to assess the prevalence of isolated anti-hbc in previously hbv infected individuals.methods: from april 2000 to september 2008, the resul...
Abstract Background and Objectives Use of kits with high sensitivity and specificity to determine the prevalence of antibodies against hepatitis B virus (anti-HBc) core antigen is important. The aim of this study was to determine the prevalence of hepatitis B virus antibody in HBsAg negative blood donors using two anti-HBc enzyme immunoassay kits (DIA.PRO and SIEMENS). Materials and Methods...
Two antigen-antibody systems were Out of 42 sera from patients with acute viral hepatitis 33 were positive for HBsAg,all HBsAg positive individuals possessed anti-HBc. From 11 blood donors sera 8 were positive for HBsAg and 9 were Positive for anti-HBc;2 leprosy sera were tested,both of them were positive for HBsAg and anti-HBc. 5 miscellaneous samples,z·were positive for HBsAg and anti-HBc...
Background and Objective: Presence of hepatitis B core antibody (anti-HBc) in the absence of hepatitis B surface antigen (HBsAg) and hepatitis B surface antibody (anti-HBs) is defined, as isolated anti-HBc. little is known about the clinical significance of the isolated anti-HBc in hepatitis B virus (HBV) infections. The aim of this study was to assess the significance of anti-HBc as the onl...

پیش زمینه و هدف: بیماری هپاتیت b به عنوان یک معضل سلامتی در سراسر جهان شناخته می شود. آلودگی ویروسی هپاتیت b و پیامد آن یک مشکل بهداشتی عمده است. این ویروس یک مخاطره شغلی برای پرسنل بهداشتی محسوب می شود.از آنجائی که بر روی عملکرد سیستم ایمنی عوامل مختلفی دخیل می باشند، در این تحقیق میزان تیتر آنتی بادی دانشجویان با گروه های خونی به عنوان به عنوان یک متغیر متفاوت در عملکرد ایمنی مورد بررسی قرار ...
چکید ه سابقه و هدف رایج‌ترین مارکر مورد استفاده جهت تشخیص عفونت HBV در اهداکنندگان خون، غربالگری HBsAg است که عدم شناسایی آن، به عللی مانند دوره پنجره، موتاسیون در ژن S و یا کاهش ساخت این Ag ، ممکن است در گیرندگان این فرآورده‌ها ایجاد بیماری نماید. از آن جایی که شیوع anti-HBc در جمعیت‌ها با شیوع HBsAg متناسب است، بنابراین لازم است در مناطقی با شیوع بالای HBV ، مطالعه‌هایی در زمینه ارزیابی...
An enzyme immunoassay (EIA) for anti-hepatitis B core (HBc) immunoglobulin G1 (IgG1) was compared with a commercial radioimmunoassay (RIA) for anti-HBc antibody (Corab: Abbott Laboratories, North Chicago, Ill.). In parallel tests of 445 consecutive samples, discrepant results were obtained with 2 samples, 1 of which was positive only by the RIA and the other of which was positive only by the EI...
