The Intolerance Screen

Using the latest ELISA testing technology, this home to lab testing kit analyses a small blood sample against 63 of the most common food intolerances that an individual will find in their daily 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.

Why IgG4?

Raised IgG4 (Immunoglobulin G) antibodies indicates a food intolerance or sensitivity. IgG4 responses are more common than the IgE, which causes an immediate reaction. Food intolerance/sensitivity reactions are more difficult to notice since they can occur hours or even days after consumption of an offending food. This means you’re less likely to accurately self-diagnose this particular response without taking an Intolerance Screen test.

Simple & Easy

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. Then, simply send your sample back to the address provided, where it is passed to our labs for testing against the intolerance and allergen items. We have a customer support team on hand 24/7 to answer your queries or offer advice on obtaining your sample.
