1. I want to get a complete Hepatitis B exam again. If my Anti HBe and/or anti-HBs are still reactive, does that mean that I have developed immunity from Hepa B (lifelong?) and I don't need vaccination anymore? Is the immunity "forever" or can I lose it?
--If you are anti-HBs reactive, HBV will be cleared when entering your body.
2. Is it possible that I don't have Hep B right now but I also don't have antibodies? I only had 1 lab test were I had antibodies and I didn't undergo any additional tests after that although my HBs antigen was non-reactive on my last 2 tests. Should I take another exam to reconfirm it?
--If your test showed anti-HBs non-reactive then it is possible "that I don't have Hep B right now but I also don't have antibodies".
3. What happens if I come in contact with Hepa B carriers through stuff like needles and unprotected sex? Can I get infected again if I have antibodies?
--Not if you are immune.
To be safe, test the value of your anti-HBs.
Thanks for the reply.
Is there any difference with regards immunity with the anti-HBs value?
From what I've read, once someone clears acute Hep B, he/she develops lifelong immunity right? Is it possible that someone can still "lose" the antibodies even if they've already cleared Hep B and it results in another infection?
Thanks.
I have never read anything in the literature about that. Natural clearance seems to confer permanent immunity.
I've got a negative results after 2 times Borderline, could it be possible that I've got lifelong immunity after the negative result?
Thanks for your time, my dear..
Positive or reactive anti-HBs usually means immunity against HBV. However, there is also the state of weak positive/reactive anti-HBs, which is why the booster shot that you read about.
