[2025-09-30T02:54:12.385096] [PI reasoning] **Determining Hepatitis B Markers**

I need to find the correct marker for a patient with a Hepatitis B infection. From the options, HBsAg is the one that will be increased during an active infection. HBcAg isn't detectable in serum, while Anti-HBsAg IgG appears after clearance or vaccination. Anti-HBc IgG indicates prior exposure. Given these details, I conclude that the answer is A: HBsAg. I'll look for citations to support this. Let's search for "HBsAg acute infection marker."
