From what I have red, flukes will be reddish or brownish, what I saw was definitely white. It would ususally come out after a pectin intake (green apple- especially when I would forget to eat them for a day or two).
Please post your result if ever you test them!
What do you mean you have to take care of other healt issues. You are still on the diet right? What is it that is troubling y our health, might I ask?
