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

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.

Had 2 of 3 Hep B vaccine shots. HEPATITIS B SURFACE ANTIBODY QL is NON-REACTIVE. 3rd shot in June. Am I protected at all until final shot?

Had 2 of 3 Hep B vaccine shots. HEPATITIS B SURFACE ANTIBODY QL is NON-REACTIVE.  3rd shot in June. Am I protected at all until final shot?

Immune System: The Immune System is quite mysterious — it has layers and layers to it actually. One 'crude' way of measuring part of this immunity is through antibody testing. That only measures one branch of the whole thing, however. With Hep B vaccine especially, there is often good T-cell immunity generated, which is NOT routinely measured. You're not quite done with the series, so I would measure afterwards. ...Read more

Does a negative hep b surface antibody test mean I have no current infection?

Does a negative hep b surface antibody test mean I have no current infection?

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. ...Read more

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

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

Ag looks for virus: Unless checking to see if recently exposed, the hbsab is what the body makes in response to seeing the outer surface (/shell) of the hep b virus, so they can attack if ever see the virus. Should only need the ab test for titer / to confirm vaccine "take.". ...Read more

Hepatitis B: R u certain the positive test was surface antigen & not surface antibody? The data u give don't fit the typical test results (see image). Perhaps the results were incorrectly reported to u. Check with doc who ordered tests. ...Read more

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

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. ...Read more

When getting a hep b titer is it part of the procedure to get both a surface antibody and surface antigen test? What are they and what's difference?

When getting a hep b titer is it part of the procedure to get both a surface antibody and surface antigen test? What are they and what's difference?

Yes: Surface antigen tests for proteins present on the surface of the virus in your blood. Surface antibody tests to see if there are antibodies in your system produced by your white cells against the protein of hepatitis b virus. If a person has received hepatitis b vaccine, the surface antibody is positive and the antigen test is negative. If both tests are positive, it indicates a true infection. ...Read more

I had my Hep B surface antibodies checked and they 10 IU/L (3x childhood vaccinations). Am I protected as an adult?

Hepatitis B vaccine: Protection against hepatitis B is believed to be complete even if antibody levels are low or can't even be detected. You could speak to your physician about being revaccinated, but it probably isn't necessary. ...Read more

No: You may acquire delta agent (hep d) at the same time you are infected with hepatitis b but the vaccine will not show an antibody titer to this other virus. ...Read more

I got my blood drawn for a hep b titer. My doctor sent it in for a surface antibody test only. Is that enough or is their more tests needed?

Yes: I'm going to assume that acute or chronic infection is not a concern and you merely had to be shown to be immune. If you are not, you may be (re)immunized or get more testing. ...Read more

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

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. ...Read more

Boosting Hep B: If you had the primary series (3 shots) of Hepatitis B vaccine, and then you had an additional shot sometime later — this will 'boost' your immunity. The Hep B series is extremely good (immunogenic), so I suspect this booster shot revved things up and your immune system is now super charged. A lot of that shot administration is for record keeping/schools etc. A titre is helpful to 'prove' immunity ...Read more

Hi my hsbag positive, confirmatory test negative for hep b, also antibody and anticore negative. I did blood test 2 times, same results. Dr said its weird.

Hepatitis B: Not sure what the so-called confirmatory test was, but as a general rule having hepatitis b surface antigen means that you have the disease. You may be in the early window period before the development of antibodies, although anticore antibody usually happens early in the course of the disease and is confirmatory. You might go ahead and take the vaccine and see if the hepb ab becomes positive. ...Read more

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. ...Read more

Slight cut from used Shave Blade in Thailand had 2006 3 shots Hep B GP lost docs Gave me from Fresh shot Nov 2015 will antibody be accurate for test?

Hep B: Yes. If you had the 3 shot series of hep b in 2006 You should still have antibodies so you can check the blood test for hep b antibodies. If it is low you still could be immune with an amnestic response, meaning levels are low but when exposed you rev right up, when in contact with hep b. It is the best though not to rely on the amnestic response,but get a booster shot. if levels low ...Read more

Might it be that a mother vaccinated against hep b pass the antibodies on to an unborn child?

Might it be that a mother vaccinated against hep b pass the antibodies on to an unborn child?

Yes: Antibodies against hepatitis b virus (hbsab antibodies from being vaccinated) are transferred from mother to fetus through the placenta. Babies get vaccinated during their first month of life and begin making their own antibodies, which is very important because the antibodies they got from mom only last about 6 months. ...Read more

Not for Hep B: You are not at risk for Hep B. But Hep B is not the only infection transmitted through body fluids.
For good health — Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex. ...Read more

Been taking baraclude (entecavir) for 4months for hep b. I have now tested pos for the antibodies. Dr says that means I'm clearing the virus. Is that true?

Yes: The human bodies response to infection includes the development of antibodies. Complete cure of hepatitis b is documented by a test called hepatitis b viral load. This should become negative and remain negative when you are cured. ...Read more
