e
Unvaccinated and has no previous hepatitis B infection
QuestionChoice
Hepatitis B surface antigen (HBsAg) is a marker of acute or chronic hepatitis B infection. As HBsAg is negative in this case, there is no active infection present. Additionally, the hepatitis B core antibody (anti-HBc) is only IgG positive if there is a resolved infection or a chronic infection. There cannot be a chronic infection (as HBsAg is negative), meaning that a resolved infection is the most likely interpretation.
