5 years ago after i tested positive for HBV, my wife tested negative, but she had antibodies: 511 UI.
She had no vaccine at least 5 years prior to that test, so we just assumed she got it from me
Last year her antibodies came back around 70 UI.
Now, i thought that she was suppose to be immunised for life if she contacted the virus from me, is it normal for the antibodies to be that low ?
The doctor never mentioned her to have a vaccine.
For people who had this issue brought up, what did your doctor said ?
