Question 1

if i received the 3 hep b doses, and 2 hep a doses as a child, will i now at 19 y/o get positive hep a and hep b antibody titers?

Accepted Answer

See below: At 24yrs, given hep B and hep A vaccines as a child - you should still be immune -It is unclear how long hep A immunity lasts after vaccine - If you are concerned, get your doctor to check

Question 2

heb b antibody test hbsab+ after hairdresser used a used blade thailand hep b vac in 2006 result today >1000  
gp explained"fully protected"true?

Accepted Answer

No risk, no worries: Your GP is correct. Ignore and do not worry about any future exposures that might risk hepatitis B. There is no possible chance you will ever catch it. There is no need to ever again be tested for hep B.

Question 3

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 4

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 5

blood transfusion 2013  3 packs does this have any  change on antibodies levels in hep b vacc from 2006? a used cut throat blade shavethailand barber.

Accepted Answer

Wow!! Ouch!!: No, transfusion of 3 units should not change/dilute your hepatitis B antibody levels. Red blood cells survive and are replenished about every 120 days. So presuming that your red blood cells replenished normally after your transfusion, your hepatitis B antibodies should be stable. It is now 10 years since your vaccine; if you are at increased risk, consider asking for antibody check. Stay well:)

Question 6

had hep b , but don't carry antibodies. what does this mean. ?

Accepted Answer

How do you know...: You had hep b? Had to have positive antibodies at some point. However, some may wind down to normal over time.

Question 7

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 8

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 9

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.

Question 10

what does a reactive hep b surface antibody mean?

Accepted Answer

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