Immunoglobulin E (IgE) is a class of antibody, which functions as part of the body’s immune system. It is associated with allergic reactions. It is found in very small amounts in the blood and testing it measures the amount of allergen-specific IgE in the blood. Elevated levels of allergen-specific IgE can suggest the presence of allergy however results must be interpreted with a full clinical history.
IgG4 antibody testing measures the level of IgG4 to specific food items. IgG4 food antibodies can result in a delayed response to a food. Circulating antibodies can affect each person differently. For some elevated antibody levels may not result in any symptoms but for others they may lead to constipation, diarrhoea, changes in bowel movements, bloating, headaches and joint aches.
