Question in which having a table in the head comes out alone discarding options: Option 1: The acute infection would be HBeAg + and ANTI-HBe - . In addition the ANTI-HBec would be IgM type (only for this last data, we would have to discard it in a direct way). Option 2: the correct one. It complies with all the characteristics. Option 3: The vaccinated patient cannot have DNA of the virus (the only thing that positivizes in a vaccinated patient is the AntiBs. IgG type). Option 4: The option that could offer more doubts. In the asymptomatic carrier (chronic carrier / seroconverted) the difference is that there is no viral DNA.
