Question 1

if my titer level to the hep b surface antibody comes back low (less than 5), should i get a booster or repeat the hep b series (3 shots)?

Accepted Answer

Yes: Especially if you are a healthcare worker or other risks for exposure.

Question 2

what does a reactive hep b surface antibody mean?

Accepted Answer

Immunity: It means you're immune, either from past infection or vaccination.

Question 3

hep b surface antibody result :borderline range non reactive verified by analysis what's this mean ? dr say wrong test vaccinated probably childhood

Accepted Answer

Other tests: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, it would have been helpful to have all the results, e.g., Antibody to Hep B core? If that was negative, your doctor is likely to be correct. See this site for info.

Question 4

does a negative hep b surface antibody test mean i have no current infection?

Accepted Answer

No: There is a lag time between when a person becomes infected with a virus (or other invader) and when antibodies begin to appear in the blood. So you can be ifected without any antibody evidence of infection early in any disease.

Question 5

what does this mean: hep b surface antibody borderline, hep b surface antigen non-reactive, hep b core ab non-reactive? all other labs normal.

Accepted Answer

Vaccinate: Consider Hepatitis B booster vaccination to protect yourself from Hepatitis B infection.

Question 6

is it required to get both a hep b surface antigen and hep b surface antibody test for a hep b titer?

Accepted Answer

Hep B Titer: A hep b titer generally refers to the hepatitis b surface antibody test. This test is used to check for immunity to hepatitis b for healthcare workers. Occasionally, a hep b titer will refer to the hepatitis b surface antigen test, a test which is used to check for the presence of the hepatitis b disease.

Question 7

i have had the hep b vaccine many years ago and have always tested nonreactive to all tests for it, but today i got a result of reactive to the hep b surface antibody qualitative. does this mean i have hep b?

Accepted Answer

: Presence of the ANTIBODY usually means you are immune to the disease, whether from vaccine or natural exposure.  Presence of ANTIGEN would mean you have the disease - if the ANTIBODY is positive now but never was before it would be good to have ANTIGEN checked &amp; also liver function tests. If those are normal &amp; no symptoms you are likely immune now

Question 8

can you tell me what can affect my level of antibodies for hep b?

Accepted Answer

Genetics: Our genetic make up controls our immune response and we all respond to antigens differently. If the antibody is low following vaccination, you should discuss getting an extra dose, with your doctor.

Question 9

what does these mean? 
negative hepatitis b, core antibody hep b core ab, tot
reactive hepatitis b, surface
antibody?

Accepted Answer

: Your statement is not clear. You probably mean: negative Hepatitis B core antibody and total reactive Hepatitis B surface antibody. If what I say is correct, you have vaccination for Hepatitis B in the past (most of Americans at you age have been vaccinated with Hep B vaccine in childhood) and you were never infected with Hepatitis B. I hope total reactive means Ab titer is above 10.

Question 10

hi please help, hepb surface antigen positive, hep b surface antigen confirmatory negative, antibody negative and anti core negative.what does it mean?

Accepted Answer

Hepatitis B testing: You should have it rechecked. Hbsag or surface antigen tests are the same, not like in HIV which has screening and confirmatory test. Normally, in the window period after an acute infection, all test for surface antigen or its antibodies are negative except for antibody to core antigen. Hbsag or surface antigen appears right after infection or exposure and disappears in recovery.
