C Diff PCR results

Hi all, my GI tested me (PCR only) and it came back positive. He does not preform EIA (toxins) testing. I have no loose stools but still have fatigue, stomach feeling super full after eating and most of the time no appetite although I still push myself to get in at least 1500 calories a day (sometimes 2000 by the hardest). I actually went from 96-100 pounds in a couple of weeks but I’m now fluctuating between 98-99lbs.

How am I supposed to know if I require further treatment without toxin testing? How do I know that I do not have an active infection? I’m so anxious with all of this. I’ve read many times people are active but do not have diarrhea and need treatment.

Thanks
