Your doctor would tell you this change is not clinically significant. Viral load fluctuate every day those numbers are only a snapshot of a moment in time.
as other members said hbvdna uop and down or undetectable means nothing it normally goes up and undetectable for long periods or all life in chronic carriers.hbsag quantity is the only parameter that tells if you are clearing actute or chronic infection, check it asap.and if you want to see if liver has any damage wait few months if ast/alt were levated and check fibroscan or if alt/ast were not very high you can also check it now
A high viral load is usually an indication of 2 things. 1.) This is an acute infection going to clear itself 2.) This is a very long term chronic infection that has been active for quite a bit of time. HBV DNA quantity tends to fluctuate. When mine when "active", it started to creep up a lot. 14,000.... 450,000..... 2 million... 14 million..... and right before I started treatment, it was going down on it's own. However, it does not mean you are clearing. It could go down and then back up and down again and back up, etc. You need more tests to determine if you are chronic or acute before anyone can answer anything. I'd suggest talking to the doctor first and ask for a full panel and if it's offered, get a hbsag in quantitive test as well.
