What does it mean when you are not immune to hepatitis B?

surface antigen (HBsAg): This means a patient has the virus and is infected with hepatitis B and is infectious to others. If this test is positive it means that a person is immune to the hepatitis B virus and does not carry infection.

Also question is, what does HEP B non immune mean?

¦ Anti-HBs [sometimes written as HBsAb] (antibody to hepatitis B surface antigen): when this is “positive” or “reactive,” it means the person is immune to hepatitis B infec- tion, either from vaccination or from past infection. (This test is not done routinely by most blood banks on donated blood.)

What is the meaning of non reactive?

A non-reactive result means that no HIV antibodies were found. This would find any exposures which happened 6 weeks prior to test or before that. A non-reactive test does not mean that a person is immune to HIV in the future, only that they do not show the virus in their body at the time of the test.

What does it mean when a blood test is nonreactive?

If either rapid test is positive, the fourth-generation test is done (on a blood test) to confirm that the person is HIV positive. It's important to know there are three types of results that can come from a rapid test: non-reactive, invalid, and reactive. A non-reactive result means that no HIV antibodies were found.
