The Science

This test uses the IgE and IgG4 in your blood sample for intolerance and allergy testing, but what does that mean?

At Test Your Intolerance, we’re proud to offer the possibility to test for both IgE and IgG4. Our Allergy and Intolerance Test Plus offers both immunological and non-immunological responses, giving you a full overview of your body and the more specific reactions caused when you are fighting foreign substances via antigens.

Why IgE and IgG4?

The interpretation of the IgE:IgG4 ratio is useful to determine the possibility of an allergic reaction. If it is higher, there is a high likelihood of an allergic reaction occurring, whereas the low ratio shows a low-grade allergic reaction. To identify food allergens which cause chronic inflammatory diseases, it’s required to test the total IgG, whereas IgE is determined only in presence of a Type I or Type 1 allergy. Scientific studies have shown that people with inflammatory and alimentary intolerance have had IgG directed against food antigens alone, but not IgE. An elimination diet elimination based on IgG antibodies (elimination of food with high IgG/IgG4 levels) as demonstrated great ability to manage symptoms in people with IBS and migraines.

We are not offering a quick solution, but the possibility to map out your body like never before. Our range of tests are not used for the diagnosis of chronic or acute food allergies or intolerances as explained in our Test Facts. The easy-to-understand test results report can be combined with your medical history and the help of your GP or an allergist to start this journey for a better version of yourself.

• Raised IgE values prove clinically significant in identifying an IgE-Mediated Allergy.
• Removal of raised IgG4 items may improve lifestyle based on testimonial evidence.
• Testing is carried out in a variety of locations worldwide.
• CE approved sample collection kit.
• 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.
• >97% reproducible results. IgG4 values may change over time with diet.

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.

Always seek the advice of your doctor or other qualified health providers if you have a medical condition and/or medical symptoms. Never disregard professional medical advice or delay in seeking it.
