Thanx for your reply..
So I will go with HbsAb test for my wife...
It should be positive or negative?? To know whether she is immune or not...
may I ask how old are you?
Yes, you can infect your wife, even though your viral load is low.
Just get your wife tested for HBsAb, she may already have immunity against HBV. If not, she should be vaccinated. It is a very effective vaccine and everyone should have it.
