Ritchie Shoemaker, MD demonstrates the Visual Contrast Sensitivity (VCS) test which is used to detect the presence of neurotoxins and biotoxins in the human body. These compounds have been implicated in diseases sush as ADHD, CFIDS, Fibromyalgia, Mold Illness and Lyme Disease.
I do environmental testing and currently reading Dr. Shoemaker's book on Mold Warriors. Very interesting stuff. I recommend the book to fellow inspectors. The VCS test is a key component for determining biotoxin exposure.
