I had similar results from an EB panel. I had mono a little over a year ago and suspected a reactivation a month ago. The doctor I went to only took the heterophile test so there was no way to know if I tested positive because of antibodies or active infection. I recently asked my primary care physician for an EBV antibody panel because I have a recurrent sore throat, post nasal drip and fatigue and was suspecting ME/CFS. In the results of my EBV panel, the Capsid IgG was 133 and the nuclear IgG was >600. My primary care seems unconcerned and just said it means I had it in the past but don’t have an active or recent infection. Does the super high nuclear IgG mean anything? Does this signify CFS? Can CFS be mild? I do feel fatigue very often and I feel like I hit a wall of tiredness sometimes and I just can’t do anything. I am pretty much able to hold down a full time job but I have to take many days off and my employer has expressed concern about that. I might just be paranoid but I feel like something is off here. Thank you to anyone who reads and replies!
