Hi,
Thanks for posting your query.
I am Dr.Ratnakar Kini and I am pleased to assist you.

HBsAg is marker for infection with hepatitis B virus. It is negative, then it indicates, your son is not having that infection.

Anti HBs is the antibody against HBsAg. Antibodies are protective substances in blood. They are naturally produced by the immune system when the virus enters your body or it can be acquired by getting vaccinated.

Your son's initial Anti HBs was too low to be protective. Hence a booster dose of the vaccine was given and now the antibody level has increased to the extent that it would protect him against Hepatitis B virus infection.

Let me know if I can assist you further.

Dr.Ratnakar Kini

Detailed answer given below.

Detailed Answer:
Hi,
I do not know why they said he cannot donate blood. If he is positive for HBsAg, then he cannot donate blood. But he is only negative for HBsAg.

Yes, you can ask questions about your husband.
