Which markers are present in the laboratory findings for an active Hepatitis B infection?

The presence of HBsAg (Hepatitis B Surface Antigen) and HBeAg (Hepatitis B e Antigen) in laboratory findings indicates an active Hepatitis B infection. HBsAg is the primary marker used for diagnosing Hepatitis B virus infection and signifies that the virus is present in the bloodstream. The detection of HBeAg indicates higher levels of viral replication and infectivity, often associated with a more severe disease course.

In contrast, Anti-HBc + IgG would signify past infection, as IgG antibodies develop after the initial exposure to the virus. The presence of Anti-HBsAg + IgM would indicate recovery or immunity following an infection rather than an active infection. Lastly, anti-HAV + IgM pertains to Hepatitis A, not Hepatitis B, highlighting that it is not relevant when discussing markers specific to an active Hepatitis B infection.
