Quizplus · Accepted Answer

The detection of anti-HBc total and anti-HBs in the absence of HBsAg and anti-HBc IgM suggests convalescent hepatitis B. This means that the patient previously had acute hepatitis B infection and has now recovered, as evidenced by the presence of both anti-HBc total and anti-HBs. The absence of anti-HAV IgM and anti-HCV rules out acute or chronic hepatitis A and C infections, respectively. The absence of HBsAg and anti-HBc IgM also rules out ongoing acute or chronic hepatitis B infections. Therefore, the most likely diagnosis for this patient is convalescent hepatitis B.
