What does it mean if anti-HBs is positive?
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. Total hepatitis B core antibody (anti-HBc):
What is the normal result of anti-HBs?
For hepatitis B surface antibody (anti-HBs), a level less than 5 mIU is considered negative, while a level more than 12 mIU is considered protective. Any value between 5 and 12 mIU is indeterminate and should be repeated.
What does anti-HBs non reactive means?
Normal results are negative or nonreactive, meaning that no hepatitis B surface antigen was found. If your test is positive or reactive, it may mean you are actively infected with HBV.
What is a positive Hep B titer value?
12.0 mIU/mL Positive Anti-HBs detected at >10 mIU/mL. Patient is considered to be immune to infection with HBV. It has not been determined what the clinical significance is for values greater than >12 mIU/mL, other than the individual is considered to be immune to HBV infection.
What does a negative Hep B antibody mean?
A negative test result indicates the virus may not be actively reproducing in the liver. In general, a person is considered very infectious when the test is positive, and less infectious when the test is negative.
Is Hep B an STD?
Hepatitis B is a sexually transmitted disease, but it is spread in other ways, too. This is a hardy virus that can exist on almost any surface for up to one month. You can get infected through contact with an infected person’s blood or body fluids.
What does low Hep B antibodies mean?
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.
Which hepatitis B marker is the best indicator of early acute infection?
Hepatitis B surface antigen (HBsAg) is the first serum marker seen in persons with acute infection.
Do you want Hep B antibody to be reactive or nonreactive?
If this test is positive or “reactive,” then your immune system has successfully developed a protective antibody against the hepatitis B virus. This will provide long-term protection against future hepatitis B infection. Someone who is HBsAb+ is not infected and cannot pass the virus to others.
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).
How often do you need hep B vaccine?

Protects other people from the disease because children with hepatitis B usually don’t have symptoms, but they may pass the disease to others without anyone knowing they were infected.
What does it mean if hepatitis B surface antibody is high?
A positive HBsAb test result indicates that a person has successfully responded to the hepatitis B vaccination or has recovered from an HBV infection. This suggests that the individual is immune and has protection from future HBV infections.
What are the 3 serological markers of early acute HBV?
HBV is a circular, partly double-stranded DNA virus with various serological markers: hepatitis B surface antigen (HBsAg) and anti-HBs, anti-HBc IgM and IgG, and hepatitis B e antigen (HBeAg) and anti-HBe.
What is normal range of HBsAg?
Laboratory tests
The dynamic range of HBsAg levels was 0.05-250 IU/mL. The samples were diluted to 1:500 or 1:1000 using ARCHITECT HBsAg Manual Diluent (Abbott Diagnostics) if the HBsAg levels were greater than 250 IU/mL.
How often do I need hep B vaccine?
How often do you need a Hep B booster?
The hepatitis B vaccine is an injection (or shot) that is generally given in the arm as a three-dose series on a 0, 1, and 6-month schedule.

What does it mean if Hep B surface antibody is reactive?
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. This protection can be the result of receiving the hepatitis B vaccine or successfully recovering from a past hepatitis B infection.
How many Hep B vaccines do adults need?
3-Dose Vaccine Series for Children and Adults
