You may also want to have your feces checked to see if you have different types of yeast in your digestive track, already lurking around.
My doctor had a special box that had to be sent to Great Smoky Mountain Labs or something similar. I went on a yeast free diet (as close a possible. Mainly got rid of carbos and certain sugars) for 6 months, and I had quite a bit of candidas in my system.
The lab even said that the strain of yeast, which is usually easily killed by nystatin, was resistant to it, and so I had to take Diflucan and have blood tests to make sure my liver is okay.
Just thought you may want to touch all the bases after you go on a yeast free diet.
