IgG Food Explorer™ (250+ Foods)
Immunoglobulin G (IgG) is a class of human antibodies, normally activated to fight parasitic infections. In food-sensitive individuals, these IgE antibodies are misdirected to mistake common foods for harmful antigens. This comprehensive test measures IgG antibodies to over 250 food allergens in just a few drops of blood, making it one of the most extensive and easy-to-use functional tests of its kind. The Food Explorer panel results will help you personalize diet and lifestyle guidance while reducing and eliminating symptoms related to adverse food reactions.
