IgG Intolerance testing


The team at Perpetual Wellbeing perform a range of food intolerance testing including the IgG test to identify foods that cause a delayed reaction. An IgG reaction can occur hours to days after exposure to the allergen; food or inhalant. This type of reaction is referred to as a delayed sensitivity reaction and is different to an IgE reaction, which occurs about the time immediately after exposure to the allergen; food or inhalant.

Representing approximately 75% of serum immunoglobulins in humans, IgG is the most abundant antibody found in the circulation and are found in all body fluids. IgG molecules are synthesized and secreted by plasma B cells.  IgG antibodies are very important in fighting bacterial and viral infections. IgG antibodies are the only type of antibody that can cross the placenta in a pregnant woman to help protect her baby (fetus).The IgG test will not identify acute immediate food allergies (IgE). If you have immediate or IgE mediated food allergies please continue to avoid these items even if they do not appear on your list of foods to avoid.  It is recommended that IgG allergy testing is only performed for infants greater than 18 months of age.

Food sensitivities can cause a wide range of symptoms and disorders. The foods that cause these delayed reactions are often hard to diagnose because of the time between consumption and the physical reaction. IgG food intolerance testing offers a useful tool for detecting the foods causing this response. The results are patient specific and provide an easy, precise and effective starting point for dietary manipulation.

If you are interested in getting food allergy or food intolerance testing done, please contact us to book an appointment.

Discounts do apply if you chose to do more than 1 panel. I usually recommend going IgG and IgA together.
