Which of the following markers in the blood is the most reliable indicator of recent hepatitis Binfection?: (A) HBsAg, (B) IgG anti - HBs, (C) IgM anti - HBc, (D) IgM anti - Hbe
Answer is C. Answer is C (IgM anti-HBc): Hbs Ag is present in recent hepatitis B infection but it is not specific to acute infection (it may also be seen in carriers). IgM anti- HBc is specific for acute or recent hepatitis, and hence is the answer of choice.
