You tested positive for the antibody (HbsAb) because you were vaccinated against hbv and your immune system developed the antibodies to protect you.
Your institute will love you to stay :-)

All your friends test negative to the HbsAb because:
1. they were not vaccinated against hbv and they have never been exposed to the hbv virus; or
2. if they were HbsAg (antigen) positive, they were infected and are now chronic.

If a person was not vaccinated against hepatitis B and tested positive to the HbsAb. This means the person was infected by Hepatitis B in the past, but has completely recovered from the infection, and has developed protection (the antibodies) against future infection. In this case, the person will also test positive to HbcAB (the core antibody).

The vaccine for Hepatitis A is different to the vaccine for Hepatitis B. There is no vaccine for Hepatitis C. Hepatitis A, B, C are all different diseases caused by different viruses. It just so happens that the diseases all affect the liver and cause inflammation (hence hepatitis - inflammation of the liver).

My HBsAg Quantitative is 20,084 UI/ml and HBV DNA < 6 UI/ml.  How high is this HBsAg? I have been taking tenofovir for two years now. How fast can tenofovir lower HBsAg?

it is very high, are you hbeag positive?if hbeag positive it can be normal to have such high hbsag

tenofovir have almost no effect on hbsag unless hbeag positives, on hbeag pos about 20% respond lowering hbsag

hbsag ranges higher than 10000iu/ml have no response to interferon too, you should wait and see the new drugs like gs9620, myrcludex

in this case  it should get down slowly by time, hbsag ranges till 50.000iu/ml or higher on hbeag pos so your result can be normal
it is very important to have more tests every 6 months to see the pattern of decline
