Re: positive for ebv
EBV or Epstein-Barr Virus is a virus in the Herpes family which most famously causes the kissing disease or "Mono". Once you've been exposed to the virus, you will always test positive for it, though it depends on which test you do. When you are exposed to EBV, your body makes antibodies of different classes against the virus.
If you have active disease, you will have a certain type of antibodies present and these will test positive on the "Monospot" test. These acute antibodies are called "Heterophile antibodies"; however, once you get better, the heterophile antibody test will be negative BUT now you will have EBV IgG antibodies which will remain positive for life even though you don't have symptoms anymore.
