A 33-year-old nurse suffered a needle stick injury. The patient used illicit intravenous drugs. One month later, the nurse developed jaundice. Which of the following finding would implicate hepatitis B as the etiology: (A) Positive antihepatitis A antibody, (B) Positive hepatitis B surface antigen, (C) Positive antihepatitis B-core antibody, (D) Positive antihepatitis B surface antibody
Answer is B. The presence of hepatitis B surface antigen means actively replicating virus, and in the context of the recent needle stick injury, this likely represents a hepatitis B infection. Ref:- Harshmohan textbook of Pathology
