A breakthrough technology that identifies immune responses to chemicals bound to human proteins. This is the first test to measure the actual immune response to chemicals, instead of simply detecting the level of chemical exposure/load which excretes from the body. Levels Indicate Exposure. Antibodies Indicate Body Burden. Toxic heavy metals and chemicals are all around us, in our environment and in our foods. When chemicals enter the body, they can bind to human tissue proteins. When this happens, it can misfold the protein into a structure that is similar to amyloid-beta. This creates antibodies against the chemicals bound to the human tissue and actually target the amyloid-beta peptide, potentially leading to amyloid plaque formation, a major contributor to the development of Alzheimer's disease. Array 11 measures an expanded range of environmental chemical toxins that bind to human tissues versus other laboratory tests that only identify chemical exposure.
