Our standard intolerance test is a fast and cost-effective way of screening for 63 of the most common food intolerances. Using ELISA testing for raised IgG4 antibodies, this test offers accurate lab results to enable you to optimise your diet.

Raised IgG4 (Immunoglobulin G) antibodies can indicate a food intolerance. IgG4 responses are more common than IgE (allergy), which cause an immediate reaction. Food intolerance reactions can be more difficult to self-diagnose since they can occur hours or even days after consumption of an offending food.

Using results from this test will provide valuable guidance with dietary adjustments required to relieve symptoms.

Purchase and Delivery

Following the simple and secure payment process, you will receive free delivery of our CE approved sample collection kit within 3 working days including easy instructions on how to complete your test.

Sample and Results

Just a few spots of blood are required using a pin-prick lancet within the kit. Send everything to our labs in the envelope provided, and we'll do the rest. We notify you when your sample arrives, and you will receive results from our lab to your email and our app in under 7 days.

The Science

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 Intolerance 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. 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 in your journey to find a better version of yourself. To find out more about the science of IgG4 testing, click here.

  • Results do not constitute a medical diagnosis on their own, but may be used by your doctor or nutritional therapist to help form a diagnosis or rule out a condition.
  • Quantitative data using an ELISA testing methodology. All values measured in Kilounits per antigen per litre (KUA/L), our scale uses a universal cut off point of 0.35 in classifying a reaction.

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).

The use of antihistamines prior to or during the blood sample collection process may affect your results, please contact our team for further advice.
