Anti-HBs question

[greenmoon]

Hello, please i have small question about HBV
I had HBV test 6 weeks post possible exposure (received an oral sex from CSW)

The result was:
Anti-HBs(CMIA)----- Positive
Anti-HBs Titer (CMIA)------ 200 mIU/ml
Anti-HBc (CMIA)  Negative

they did not checked the HBsAg at that time!. Afterwards, 6 months post exposure i had a routine test  for different STDs, when looking to the report i have noticed that they checked only the HBsAg and it was negative, they didn't know about my previous tests since i had this test in different lab.

I just want to interpret my result please , i am a bit paranoid.
does the Anti-HBs goes down to negative if some body get infected? since they did not check the Anti-HBs nor the Anti-HBc in my last test. i just want to be sure that my tests are conclusive because i get lost when reading on the internet.

I test negative for all other STDs (thanks GOD)

Thank you so much for your help and your understanding.

Thank you for your answer, actually i didnt understand this sentence ""after having hbsab it can enter liver cells and start a real infection"

i can say that i am protected + HBsAg negative 6 months post possible exposure + Anti-HBc negative 6 weeks after exposure, so i am protected and dont have HBV regarding this exposure?

maybe i am insisting for your answer, but really i need it? thank you

hbv is like water for you, after having hbsab it can enter liver cells and start a real infection

even if unvaccinated all adults clear hbv, so i am not saying inject hbv into your body but you cant do nothing to get infected by hbv, you are totally protected by 200miu/ml of hbsab

Thank you so much for ur help,i really appreciate it.

I had a Negative Anti-HBc 6 weeks after exposure, then i thought that maybe 6 weeks are not enough to get conclusive result, However, the Dr said that i am vaccinated, i remember that I had vaccination when i was kids and now i am 28 years old.
because of my obsessions after the exposure i was thinking that maybe the vaccination is not enough,this why i was trying to interrupt my test and look for all possibilities.

Now final question please to conclude every thing, i had  HBsAg negative 6 months post possible exposure plus Anti-HBs Titer 200 mIU/ml and Anti-HBc negative 6 weeks after exposure, that consider conclusive right? and no infection.

i hope that you understand my anxiety,i am deeply grateful for you.

you already had hbv somehwere in your life and now you are immune for life, also hbv gets cronic only on early childhood, babies at birth or immune suppressed, so it is not a concern at all for you

to make it more clear i am afraid form following case i found:
HBsAg :negative
anti-HBc positive
anti-HBs negative

Interpretation unclear; four possibilities:
1. Resolved infection (most common)
2. False-positive anti-HBc, thus susceptible
3. “Low level” chronic infection
4. Resolving acute infection

so i was thinking about the worse scenario, HBsAg negative and my anti-HBs become Negative after about 5 months (i dont know if that possible since i did not check )and assuming anti-HBc positive is that possible? or i am simply vaccinated so no need to worry??
