During the window period of Hepatitis B, which serologic markers are present?

• A. HB surface antigen and Anti-HB core IgG
• B. Anti-HB surface IgG and Anti-HB e IgG
• C. Anti-HB core IgM and Anti-HB e IgG
• D. Anti-HB core IgM and Anti-HB e IgG

Answer: (C)

During the window period of Hepatitis B, the serologic markers that are typically present include Anti-HB core IgM and Anti-HB e IgG. The window period refers to the time after an individual is infected with the virus and before the development of detectable Hepatitis B surface antigen (HBsAg) and before the production of Anti-HB surface antibodies (anti-HBs). At this stage, the individual may have cleared the HBsAg but has not yet developed enough anti-HBs. During this time, the immune response is producing Anti-HB core IgM, which indicates acute infection, and Anti-HB e IgG, which indicates some level of progression in the immune response to the virus. This combination reflects an ongoing immune response to the Hepatitis B virus while the person may not have fully transitioned to a state where protective antibodies (anti-HBs) are present. Understanding the window period is critical for diagnosing Hepatitis B infection accurately and interpreting serological tests correctly.
