What is the minimum length of time that the patient’s serum must remain positive for HBsAg before the individual is referred to as a chronic carrier?

• A. 3 Months
• B. 12 Months
• C. 6 Months
• D. 24 Months

Answer: (C)

In hepatitis B, chronic carrier status is defined by the persistence of HBsAg in the serum for six months or longer. If HBsAg remains detectable for six months or more, the infection is considered chronic, even if symptoms are absent. If it clears before six months, it’s viewed as an acute infection. So, six months is the minimum duration needed to label someone a chronic carrier. Shorter periods would fall into acute infection, while longer thresholds would not reflect the standard clinical definition.
