Ten years ago, when my lungs were full of mucus, the test came back as candida. ID doctor said, "we don't treat that anymore". I found "Candida Cleanse" on line and used it. 6 months later, my lungs were clear again.
It is possible that the tests have become more specific, but the treatments have not. It won't hurt to try cleaning out with the treatments available. I also use Dr. Tobias Lung cleanser, but there are other popular products used by many in the support group.
