What does it mean if a titer is positive?
A titer may be used to prove immunity to disease. A blood sample is taken and tested. If the test is positive (above a particular known value) the individual has immunity. If the test is negative (no immunity) or equivocal (not enough immunity) you need to be vaccinated.

The three tests generally include HBsAg, antibody to HBsAg, and antibody to hepatitis B core antigen. This allows the doctor to know whether you could benefit from vaccination, or if you have active or chronic hepatitis B and need counseling, care, or treatment.
What does hepatitis B surface antigen ( HBsAg ) mean?
Hepatitis B surface antigen (HBsAg): A protein on the surface of hepatitis B virus; it can be detected in high levels in serum during acute or chronic hepatitis B virus infection. The presence of HBsAg indicates that the person is infectious. The body normally produces antibodies to HBsAg as part of the normal immune response to infection.

Hepatitis B surface antibody (anti-HBs): The presence of anti-HBs is generally interpreted as indicating recovery and immunity from hepatitis B virus infection. Anti-HBs also develops in a person who has been successfully vaccinated against hepatitis B.

HBsAg will be detected in an infected person’s blood an average of 4 weeks (range: 1–9 weeks) after exposure to the virus. About half of patients will no longer be infectious by 7 weeks after onset of symptoms, and all patients who do not remain chronically infected will be HBsAg-negative by 15 weeks after onset of symptoms (8).
