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 ...
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. ...

HBs generally means the conclusion of and immune to HBV infection. Principle of the Assay Hepatitis B surface antigen antibody ELISA kit adopts the sandwich principle as the basis of the assay. The wells of polystyrene mcroplate have been coated with HBsAg. When the test sample containing...
What is a Surface Antibody Titer? This is the blood test that checks for immunity to Hepatitis B. A “positive” or “reactive” anti-HBs (or HBsAb) test result indicates that a person is protected against the hepatitis B virus. This protection can be the result of receiving the hepatitis...
This strategy was leveraged to produce the first World Health Organization endorsed malaria vaccine, RTS,S/AS01, which uses hepatitis B surface antigen (HBsAg) as a carrier and a means to provide structural support for virus like particle formation to display the antigenic domains of the malaria...
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...
Conclusions Our study suggests that the level of serum M2BPGi would be a simple and reliable diagnostic tool for identi- fying liver fibrosis stage in Chinese patients with chronic hepatitis. Abbreviations ALT: Alanine aminotransferase; anti-HBc: Antibody to hepatitis B core a...
Hepatitis B antigens and markers of infection. 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...
Donors had been vaccinated one to 10 years earlier with at least two doses of recombinant hepatitis B vaccine. All had responded well to the vaccination, showing anti-HBs antibody titers from 29 mU/ml to >500 mU/ml (see Table 3). PBMC were cultured with HBs-derived HTL peptides at 20...
