Product Description

The standard at home food 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 blood spot test offers accurate lab results to enable you to adjust your diet to reduce or avoid triggers.

Results are delivered to you via one easy-to-understand report. The personal food intolerance report includes the following key elements:

– Explanations of the testing process.

– IgG4 reactions to items screened.

– Elimination diet recommendations.

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

Our expert team of intolerance technicians and lab managers have over 20 years of combined experience in allergy & intolerance testing and work from our category 2, ISO9001 accredited allergy and intolerance testing laboratory.


Food Intolerances. Including common causes of intolerance such as eggs, grains, fruits, wheat and fish.
