This test uses the IgG4 in your blood sample for intolerance testing, but what does that mean?
IgG and IgE antibodies play an important role in our immune system. The immune system helps our body to fight infections and inflammation caused by external invaders known as antigens like viruses, bacteria, parasitic worms and proteins. We have four classes of IgG antibodies: IgG1, IgG2, IgG3 and IgG4(1). For the INSERT TEST test we are using IgG4 to help us in the identification of those non-immunological responses that can be the cause of common symptoms like: bloating, headaches, stomach pains and diarrhoea.
Why IgG4?
The IgG4 antibodies can influence the inflammatory response but not activate it in. We are using IgG4 in our intolerance tests because we are investigating delayed symptoms that could be associated with food and non-food intolerances (1,2). These do not cause an immediate immunological response, however, could still be causing you problems. For food intolerance, the presence of specific IgE and IgG antibodies can be observed. Some subclasses of IgG (mainly IgG4) inhibit the degranulation of basophils and mast cells and the activation of the complement cascade (2).
At Test Your Intolerance, we use IgG4 exclusively for qualitative intolerance testing. Our tests are not used for the diagnosis of acute or chronic food intolerances; however, we are helping you to draw a map of the reactions that could be the cause of your symptoms. 60% of the world’s population suffers from food intolerance to at least one food antigen. This test is not a quick fix but can help you into your journey to find a better version of yourself. To find out more about the science of IgG4 testing, click here.

Important
Blood (ELISA) tests define an intolerance/sensitivity as a specific IgG4 antibody reaction and an allergy as a specific IgE antibody reaction (IgE-Mediated).
