What type of infection can a positive result in Hep A AB Total indicate?

• A. Current infection only
• B. Past infection only
• C. Both past and current infections
• D. No infection

Answer: (C)

A positive result for Hep A AB Total indicates the presence of antibodies to the hepatitis A virus. This means that the individual has been exposed to the virus at some point, developing an immune response. The presence of these antibodies can result from either a past infection or a current infection, as the body produces antibodies in response to the virus regardless of how long ago the infection occurred. In the context of hepatitis A, the total antibodies (IgM and IgG) do not differentiate between a current and past infection. If the individual had a recent infection, IgM antibodies would also be present, but the total antibodies indicate that there is a history of exposure and immune response to the virus. Thus, the correct interpretation is that a positive Hep A AB Total result can indicate both past and current infections, explaining why this choice is accurate.
