hmmmm... usually it takes a month before hbsag to register in the blood so maybe when u had your test u were just recently exposed so come feb 2011 it was now detected because it was already in your system for quite sometime already.
I had the first shot of vaccine feb 2011 and i tested positive to hbsag 27th july 2011 before my second shot..my partner tested negative and his taking the vaccine at the moment...does that mean i have chronic hbv..what is the way to go?
OCTOBER 2010 - BOTH HBSAG-
FEB 2011- 1st SHOT
JUL 2011- HBSAG+ (you), HBSAG- (him)
usually it takes 3-6 months for HBSAG to register in your blood, so most likely you're having an acute infection, but your info is incomplete, you should have others like HBEAG, IGM, IGC, etc in those tests. if he again tested negative then you may have gotten it from another source.
Im hbeag +, igm -, hbcore total + alt 14, ast 18. he tested negative to hbeag,hcv and hiv..we've been dating for 3yrs
