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.

Why IgG4?

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

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.
