Ok to take Chlorophyll, charcoal, probiotics before medical tests?

I'm going to see the doctor so he can run tests this week: Kidney, liver, thyroid, hormone, stool, etc. I'm not taking the TMAU test just yet so they can rule out other medical conditions. Can I continue taking the chlorophyll, charcoal, and probiotics? Will those three supplements impact my stool results? (Sorry if I'm blunt here but really need to know.)I'm also going to start watching what I eat to reduce the choline in my system.

The chlorophyll seems to help the bo and the probiotics helps with the BMs. As for the charcoal, I have to be careful that I only take one after a meal on my bad days because they make me nauseous.
