Blood Drug Testing

If I have had a hepatitis vaccination, should a hepatitis test on a blood test turn out positive?

Just for the sake of it, since the doctor had to take blood from me anyhow, I asked him to do me an AIDS test, which also includes hepatitis tests - I had had a hepatitis vaccination a year ago, and I'm not sure if it's the same type that came on positive, but is that the case, that if you've been vaccinated, the tests turn out positive?

1. Well there is more than one type of hepatitis so if you got a vaccine for Hepatitis A and you took a blood test that came positive it might be positive for hepatitis B. Also the purpose of a vaccine is to ready the body's immune system for an attack by the bacteria/virus so if you or if his is hypothetical, whoever had hepatits before they took the vaccine would return positive for hepatits Here in canada there is a twinrix vaccine which is the best protection against it although it is too late if you already have it anyways best of luck
2. No. When they vaccinate you they use 'weak' bacteria that kicks in your immune system to fight it. So, it would not show up positive. On another note, my Mother had Tuberculosis as a child, and passed the antibodies to me, so I react positive to a TB test. b
3. Yes it can turn up positive if you had the vaccine and your body did the job of producing antibodies. I am guessing you had the Hep B vaccine, so the test that tells them that you are positive is the anti-HBs test. It will also be positive if someone had the virus and their body also developed antibodies to the virus.
4. There's 5 different things that they test for. If you're looking at the paper yourself, the HBsAb should be positive if you've had the Hepatitis B vaccine. I think one of the others should be positive too if you've had the Hepatitis A vaccine, but I'm not sure if I'm right or which one it is. The rest should be negative.
5. The vaccine was for Hep B? I don't think there is a vaccine for Hep C and Hep A is pretty common and tends not to be very serious. So when they test you for Hep B, there is a test for antibodies and a test for the virus. If you had the vaccine, you should test positive for Hep B, this means that your immune system has responded to the vaccine as was expected. In your case, you should be concerned if the test for Hep B surface antigen was positive, this means you have the virus. You should also be concerned if you test positive for antibodies to Hep C, since this would not be due to the vaccine.
