What result indicates someone is susceptible to hepatitis B?

• A. HBsAg: pos, Anti-HBc: neg, Anti-HBs: neg
• B. HBsAg: neg, Anti-HBc: pos, Anti-HBs: pos
• C. HBsAg: neg, Anti-HBc: neg, Anti-HBs: pos
• D. HBsAg: neg, Anti-HBc: neg, Anti-HBs: neg

Answer: (D)

The result indicating susceptibility to hepatitis B is when HBsAg is negative, Anti-HBc is negative, and Anti-HBs is negative. This combination means that the individual has not been exposed to the hepatitis B virus (as indicated by the negative HBsAg and Anti-HBc) and has not been vaccinated or developed immunity to the virus (as indicated by the negative Anti-HBs). In contrast, a positive HBsAg would indicate an active infection or carrier state for hepatitis B, while a positive Anti-HBc might suggest past exposure or an acute infection. A positive Anti-HBs would suggest immunity, either from vaccination or recovery from a past infection. Therefore, the specific combination of negative results in this scenario clearly denotes that the individual is susceptible to hepatitis B.
