Hepatitis B surface antibody (HBsAb) is an antibody that develops in response to the hepatitis B surface antigen (HBsAg), which is the outer shell of the hepatitis B virus (HBV). Positive HBsAb indicates past or resolving infection, and it remains detectable for life. ...
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 ...
Results Hepatitis B surface antigen (HBsAg) testing was transiently reactive following administration of G–CSF when examined using a test kit from one manufacturer, but not another. No other cause was found. Conclusion A false-reactive test for HBsAg using one manufacturer's test kit can occur ...
At our institution, we have been using the Roche Diagnostics hepatitis B surface antigen (HBsAg) assay (Elecsys HBsAg) (1) and the hepatitis B surface antibody (anti-HBs; also known as HBsAb) assay (2). A new generation of HBsAg assay was recently introduced-the Elecsys HBsAg II-that off...
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...
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...
A gold electrode modified by hepatitis B surface antibody covalently bound to self assembled thiourea monolayer has been fabricated to detect the hepatitis B surface antigen. 用硫脲在金电极表面自组装单分子层 ,然后通过戊二醛耦联乙型肝炎表面抗体 (抗 -HBs) ,得到电位型的乙型肝炎抗体膜免疫电极 ,用于检...
HBsAb (Hepatitis B Surface Antibody): This antibody is produced in response to the HBsAg. The presence of HBsAb can indicate either a past infection or immunity due to vaccination. HBeAb (Hepatitis B e Antibody): This antibody targets the "e" antigen of the hepatitis B ...
Hepatitis B virus has infected a third of the world’s population, and 296 million people are living with chronic infection. Chronic infection leads to progressive liver disease, including hepatocellular carcinoma and liver failure, and there remains no
In contrast to another hepatotrophic RNA virus, HCV, HAV has a high degree of genomic and resultant antigenic conservation. The spontaneous mutation rate of HAV is low and antibody-mediated immunity from previous exposure or vaccination is effective in preventing HAV infection. HAV is charac...
