My Bloodwork

The PA-C from my doctor's office called me just now to let me know the results of the bloodwork they had done last week. Everything came back basically normal. My potassium is low so she told me to eat more bananas (haha) and also, she said that it looks like I have had mono in the past. I haven't the faintest clue as to when I could've had it...but she said that's a good thing because you can only have it once so now I'm immune. She also said the strep throat that keeps coming back must just be that, strep throat.
