Hep a versus hep b antibodies
I’m I correct in thinking that hep B antibodies can differentiate between having a past infection versus being vaccinated, whereas hep A antibodies cannot differentiate?
(I think it has something to do with the core antibodies test and the way the vaccine was created?)
Comments
For a really short answer, the hep B vaccine would give you what is called “surface antibodies” and an infection would give you “core antibodies.”
For hep A, you would see IgM and IgG antibodies. IgM are the antibodies your body makes at the beginning of the infection which fade as you recover. The IgG are the enduring ones your body makes in response that signal past infection on testing.
