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.
IgG4 antibody testing for food intolerance does not test for coeliac disease, lactose intolerance, histamine intolerance, food allergy (IgE reaction) or any other medical condition.
If you have any medical conditions, are pregnant, breast-feeding or below the age of 18 we recommend that any dietary changes are made under the supervision of a healthcare professional.
Please note this is not an allergy test.
