A 16-yeаr-оld mаle exhibited the fоllоwing symptoms: fever, fаtigue, and a sore throat. He went to his primary care physician who ordered a rapid strep test and another for infectious mononucleosis. The rapid strep test was negative but the test result for infectious mononucleosis was weakly positive. The patient mentioned that he thought he might have had mononucleosis a few years earlier, but he was never officially diagnosed at that time. Now, his serum was sent to be tested against specific Epstein-Barr viral antigens. The results indicated the presence of only IgM anti-EBV antibodies. How do you know that this is a new and not a re-activated case of mononucleosis?
