In this CME we will look at new and old data regarding testing and clinical assessment, the implications and limitations of that data, and how it fits real world case management. We will look at the other testing and assessment involved in treating the whole person as well as how mold – mycotoxin illness is a core (but not every) factor in a complex chronic illness case.
