An IgG4 response to food is actually more common than the IgE response, which causes an immediate reaction. These food sensitivity reactions are more difficult to notice since they can occur hours or even days after consumption of an offending food. In some cases, a person’s reaction to a food may occur several days after eating the offending food and the link between the food and their symptoms may not be connected. These hidden food “allergies” are actually food “sensitivities” and are caused by increasing blood levels of IgG4 antibodies in reaction to specific foods. This profile measures the IgG4 levels in serum that react to 90 different foods, including commonly eaten foods such as corn, milk, egg, and wheat.
