Test Results

Hi can someone help me interpret these blood result for Hep. B. I had a test done and it says Hep. B Core antibody Negative and a Hep. B Surface antibody value of 25.99. This was after 7.5 weeks after one time unprotected vaginal sex. Does this mean I don't have HBV and I am immune? Do I need to test again? Thanks.

Yes.

You've probably been vaccinated.

so anything that has a value greater than 1 for HBsAb means that I am immune to Hep. B? Since my value is 25.99.

Yes, that is what this means.

Here is an explanation of the test that I found -

The description of the hepatitis B blood markers and the chart below can help you better understand your hepatitis B test results.

The hepatitis B "surface antigen" (HBsAg) is part of the hepatitis B virus that is found in the blood of someone who is infected. If this test is positive, then the hepatitis B virus is present.

The hepatitis B "surface antibody" (HBsAb or anti-HBs) is formed in response to the hepatitis B virus or vaccine. If this test is positive, then your immune system has successfully developed a protective antibody against the hepatitis B virus. This can provide long-term protection against future hepatitis B infection. Someone who is surface antibody positive is not infected, and cannot pass the virus on to others.

The hepatitis B "core antibody" (HBcAb or anti-HBc) does not provide any protection or immunity against the hepatitis B virus. A positive test indicates that a person may have been exposed to the hepatitis B virus.

It looks like you have been vaccinated for hep B, which is a good thing.
