The Intolerance Screen
This home-to-lab testing kit analyses against 63 of the most common food intolerances that an individual may find in their diet. The test analyses the blood samples against raised IgG4 antibodies to give you accurate results within 7 working days upon receipt at our laboratory.
Simple & Easy
A testing kit is mailed on purchase and should reach you within 1-3 working days. Included are instructions and everything you need to easily take a small sample and return it to our labs in the envelope provided.
Raised IgG4 (Immunoglobulin G) antibodies indicate a food intolerance or sensitivity. IgG4 responses are more common than the IgE, which cause an immediate reaction. Food intolerance/sensitivity reactions are more difficult to self-diagnose since they can occur hours or even days after consumption of an offending food. Read more about IgG4 here
The easy to use testing kit is mailed immediately on purchase and should reach you within 1-3 working days. In the box, there will be full instructions provided on how to complete the pin-prick and blood spot sample in a fast and pain-free manner.

What items does this test for?
- Raised IgE values prove clinically significant in identifying an IgE-Mediated Allergy.
- 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.
- Testing is carried out in a variety of locations worldwide.
- CE approved sample collection kit.
- 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.
Blood (ELISA) tests define an intolerance/sensitivity as a specific IgG4 antibody reaction and an allergy as a specific IgE antibody reaction (IgE-Mediated).
All information in the reports produced is intended to support nutritional advice to optimise your diet. The results cannot be used to diagnose, treat or cure medical/health conditions.
