While IgE antibodies are responsible for acute allergic reactions, IgG-mediated manifestations take much longer to develop. IgG antibodies play a significant role in the shaping of the body’s normal immune system. Food Detective® is a point-of-care test that screens for the presence of IgG antibodies to 59 common foods, giving results in 40 minutes. FoodPrint® is a laboratory-based system which utilises an innovative, colorimetric microarray-based ELISA technology for the measurement of food-specific IgG antibodies in human serum or plasma for over 200 different foods. Both systems use specific food extracts to identify the corresponding level of circulating IgG antibodies to these potential antigens and can therefore detect foods to which the immune system is reacting.
