Maybe the Lerner patients can answer this... I am wondering why it is that when Dr. Lerner tests for HHV-6 and CMV, he runs IgM AND IgG tests; but when he tests EBV, he tests only IgM and not IgG (at least this is true for me). My HHV-6 is positive for IgG antibodies, but initially (including when I first had mono a year ago), my EBV tested positive on IgM. But for the last 4 months, my EBV has been negative on IgM. But, in Montoya's article they tested patients for EBV IgG antibodies-- why does Lerner not do that?
