Related to this, Anti HBSAg indicates immunized against Hepatitis B
If you test negative HBSAg, you don't have the disease.
What's next if you test positive for HBSAg, order HBE Ag and anti-HBE Antibodies !

Yes you can be antigen (+) without fever and jaundice...if you received the vaccine a short while ago. Even in desease the HBsAg will disappear after the acute fase to give rise to the HBeAg (marker for infectivity in the window period). The difference between immunity after disease and immunity after vaccination is that after vaccine you have HBsAb, and after disease you have HBsAb and HBcAb (core antibody).
To AAAAA: HBsAG does not confer immunity. It states the presence of capsule ID tags, if you will, in the blood stream. It is HBsAb (antibody) that indicates that your body has developed a defense against the Ag. There is no HBeAb to my knowledge, and if there were, there is no practical use for it. You may have the disease even if you test (-) for the Ag IF you are in the afford mantioned window period.
Hepatitis serology is complicated until you apply the basic concecpts that an Ag is what the body looks for and an Ab is what the body produces against the Ag.

You can not learn medicine by reading the book !!!
There are Hepatitis B e antigen and also
Hepatitis B e antibodies.
Hepatitis B serology is not complicated at all !
If you test positive for HBSAg , HBeAg (-) negative, and positive for HBe antibodies and normal liver function , and the Hepatitis B viral load is less than 10 to the 5th (100,000) , you are in an immunotolerant state .
Most family doctors have no experience in
dealing with so-called different states of hepatitis B !
You have to read the most up-to-date
information from teh hepatology journals and see real patients!

Anti HBSAg does confer immunity.
Anti HBS Ag means antibodies against BBS Ag !!!!

I'm really sorry dood, but Ag means antigen and Ab means antibody until proven otherwise to me. Please state your source.

I would also REALLY appreciate it if you could explain to me a bit more about the immunotolerant state and the way it is managed. It is something new to me and I'm interested.

guayoman...if you look at AAAA's post he mentions AntiHBsAg...which is the antibody and so does confer immunity.
In other words...AntiHBsAg is the antibody against HBsAg.

Dr. Guayoman,
I had a hard time when I took three different exams.
The British, American and Canadian medical exams.
They are all slightly different !
The American used their units, the British sometimes
penalizes you if you makes a mistake.
And the Canadian has both English and French !
So I learn there are so many different minor
versions.
There are actually many different genotypes of
Hepatitis B. Also the neonatal transmission of
Hepatitis B is a totally different subsets.
Anti HBSAg = you develops antibodies against HBSAg
So you are imune to the hepatitis B !

Dr G,
HBeAg is a very important marker
In Hepatitis B, we follow the
seroconversion of HBeAg to
Anti-HBeAg or if you prefer
(HBe Antibodies) , liver function
test, and also ultimately, biopsy
of the liver if indicated !
