Measures IgG and IgA immune reactivity to 90 of the most commonly consumed raw and/or modified foods, including dairy and eggs, grains, beans, nuts and seeds, vegetables, fruit, fish and seafood, meats, herbs, spices, gums, brewed beverages, and additives. It can detect dietary-related triggers of autoimmune reactivity and monitor the efficacy of customized dietary protocols. These antibodies are detected in patients with broken oral tolerance, leaky gut, inflammation, and autoimmunity, and their detection can help in the monitoring of dietary protocols.
