She will find both mundane and exotic pathogens. She found Q-virus in me, which is transmitted by working around cattle. I haven't spent time around cows, but I spent a long time in the third world, so she said it could have been from that. Plus the usual reactivated EBV. And if you feel truly "sick", she can track it down to the exact cytokine (ie, IL-6, TNF-a, etc etc). It is all very certain, no question.
