A positive or "reactive" result on the HBsAb test means that you're immune to the hepatitis B virus. A negative or "non-reactive" result means that you're not immune to the virus. This article explains what the hepatitis B surface antibody test is for, when it is used, and how the ...
However, 48% of the sera from 58% of the 33 species were reactive for antibody to hepatitis B surface antigen. This reactivity was blocked by human serum positive for hepatitis B surface antigen but not by control human serum. The antibody to hepatitis B surface antigen was generally present...
All animals received the 3 dose ENGERIX-B® hepatitis B virus vaccine series, starting with the first dose given within 4 days of age, then 6 and 24 weeks of life, which mirrors the human infant vaccination schedule. All 10 of the animals produced a robust HBsAg-specific antibody response...
Hepatitis B surface antigen (HBsAg) indicates either acute or chronicHBVinfection. People with positiveHBsAgare infectious and can transmit the virus to others. The IgM subclass of antibody to thehepatitis B core antigen(IgM anti-HBc) indicates acute infection while total IgG anti-HBc is a nonspe...
Anti-HBc (antibody to hepatitis B core antigen), indicates current infection with HBV or the individual has been infected at some point in the past. A positive anti-HBs (antibody to HBsAg) result shows immunity to hepatitis B either from a resolved HBV infection or vaccination. Molecular ...
Project ECHO HBV monitoring for patients on HCV treatment. Abbreviations: HBV, hepatitis B virus; HCV, hepatitis C virus; HBsAg, hepatitis B surface antigen; anti-HBc, hepatitis B core antibody; anti-HBs, hepatitis B surface antibody; HBV DNA quant, quantitative HBV DNA; ALT, alanine aminotran...
The risk of hepatocellular carcinoma (HCC) increases in chronic hepatitis B surface antigen (HBsAg) carriers who often have concomitant increase in the levels of benzo[alpha]pyrene-7,8-diol-9,10-epoxide(±) (BPDE)-DNA adduct in liver tissues, suggesting a possible co-carcinogenesis of Hepatiti...
Hepatitis B virus (HBV) surface antigen (HBsAg) screening in blood banks reduced the risk of HBV transmission through transfusion. However, the detection of occult HBV infection among blood donors is imperative for improving blood safety. The aim of this study was to determine the frequency of ...
Anti-HBc IgG remains at high levels for the patient's lifetime, whereas anti-HBs antibody titers may fluctuate and become undetectable after several years. Quantitative HBsAg assessment may be useful during the course of acute hepatitis B, because if the HBsAg level does not rapidly decrease, ...
This novel humanized antibody will be useful in the im- munoprophylaxis of HBV infection. Keywords: antibodies, monoclonal; hepatitis B sur- face antigens; hepatitis B virus; Pan troglodytes; im- munization, passive; immunotherapy Introduction HBV infection is a worldwide public health problem ...
