Depends on 4 results: Once infected, a person keeps his EBV virus forever in his body. EBV is common. There are usually 4 antibodies tested. A patient should have a reason before being tested (he has some illness). If positive for past EBV, that just means a past infection. If positive for current EBV, that means a current infection. If both, it could be a re-activation of EBV, or a resolving "current" EBV infection.
