Oh my gosh, Tristen, you poor kid. You must be really poisoned. I think the theory behind these tests is that neurotoxins affect microcirculation, which affects our eyes' ability to see contrast. But the visual tests could be an indication of any kind of neurotoxins. For example, people with Lyme infections or other tick borne infections have all those bacteria acting like neurotoxin factories inside them. So it could help to get the HLA-DR genetic test, which can be a clue pointing you toward which neurotoxins are getting you. The online VCS test was one of the first things I did after reading "Mold Warriors". Coming out positive for neurotoxins on it encouraged me to do the blood tests and to send a sample of my carpet fibers to Mouldworks. A year and a half later I did the VCS test in a doctor's office with cards, and the results were very similar to the online test.
