Got my wife's cold and liver or kidney #'s

I happened to get my wife's summer cold. I can't sing or talk normal. Just a setback. 

My dr office called my wife when she was at work and I'm completely off any antibiotics and need to go in for labs for my liver or kidney numbers. Idk how I'll find out since,  if your bloodwork if fine, they don't call. I'm sure I'll get a call. I hope whatever infection I have in my toe is healed up. We cant afford another time off from work for another amputation. We just can't afford it.
