What are the markers of hepatitis B?

The serum markers of hepatitis B virus (HBV) infection are complex, mainly including HBV surface antigen (HBsAg) and antibody to HBsAg, HBV e antigen (HBeAg) and antibody to HBeAg, antibody to HBV core antigen.

What marker indicates immunity to hepatitis B infection?

Anti-HBs: Antibody to hepatitis B surface antigen is a marker of immunity. Its presence indicates an immune response to HBV infection, an immune response to vaccination, or the presence of passively acquired antibody.

What does reactive hepatitis B antibody mean?

anti-HBs or HBsAb (Hepatitis B surface antibody) – 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 B vaccine or successfully recovering from a past hepatitis B infection.

What are the most frequent serological markers for hepatitis B?

Hepatitis B surface antigen (HBsAg) is the hallmark of HBV infection and is the first serological marker to appear in acute hepatitis B, and persistence of HBsAg for more than 6 months suggests chronic HBV infection.

What are the viral markers?

Viral Markers Test (HIV, HBsAg, Anti HCV) It is a Screening test for HIV, Hepatitis B and Hepatitis C.

What are the 3 serological markers of early acute HBV?

Serological markers for HBV infection consist of HBsAg, anti-HBs, HBeAg, anti-HBe, and anti-HBc IgM and IgG.

What does anti-HBs positive mean?

■ Anti-HBs [sometimes written as HBsAb] (antibody to hepatitis B surface antigen): when this is “positive” or “reactive,” it means the person is immune to hepatitis B infec- tion, either from vaccination or from past infection.
