The generally accepted titer level associated with the minimal level of protection against HBV is 10 International Units/L, although this is debatable. A titer level between 10 and 100 International Units/L may be an indication for revaccination of immunocompromised patients.

What is a normal Hep B titer?
The generally accepted titer level associated with the minimal level of protection against HBV is 10 International Units/L, although this is debatable. A titer level between 10 and 100 International Units/L may be an indication for revaccination of immunocompromised patients.
What does a high Hep B titer mean?
A positive HBsAg test result means that you are infected and can spread the hepatitis B virus to others through your blood. anti-HBs or HBsAb (Hepatitis B surface antibody) – A “positive” or “reactive” anti-HBs (or HBsAb) test result indicates that a person is protected against the hepatitis B virus.
How many Hep B titers do you need?
If you are at risk for occupational exposure to Hepatitis B Virus (HBV) and you cannot provide documentation of receiving 3 doses of Hepatitis B vaccine in the past, the recommendation is to repeat vaccination with the complete 3-dose vaccination series, with post-vaccination antibody titer testing 1 to 2 months after …
What does it mean to be HBeAg positive?
The hepatitis e antigen, or HBeAg, is a marker of an actively replicating HBV virus infection. Those with a positive HBeAg have active replication in their liver cells, more of the virus circulating in their blood, and as a result, they are more infectious, with a higher likelihood of transmitting HBV to others.
What does a positive hepatitis B core IgM mean?
IgM antibody to hepatitis B core antigen (IgM anti-HBc): Positivity indicates recent infection with hepatitis B virus (<6 mos). Its presence indicates acute infection.
What if my hep B titer is low?
If the test shows the titer is less then 10 mIU/mL the general recommendation is to complete the series again using a different brand of vaccine (e.g. if you received Engerix B, the first time, switch to Recombivax the 2nd time or vice-versa).
What if my hep B titer is negative?
A Word From Verywell. If all of your hepatitis tests are negative, it indicates that you have not been exposed to the virus and are not immune. If this is the case, talk to your healthcare provider about getting vaccinated whether or not you are at risk of hepatitis B.
Does Hep B viral load fluctuate?
Conclusion: Treatment naive CHB patients in immune clearance phase show short-term spontaneous fluctuation of HBV DNA, and nearly 25% of the patients have HBV DNA fluctuation >0.5 Log IU/ml. Such fluctuation is related to liver inflammation and quantity of HBV DNA.
What does positive titer mean?
Titers are blood tests that check your immune status to vaccinations or diseases you may have received in the past. If you’re titers results are positive, it means that you have adequate immunity to a particular infectious disease. Therefore, you do not need to get that particular vaccine.
