Test4 Limited detect food sensitivities by measuring IgG antibody reactions using the ELISA method, a globally established technique for laboratory analysis that is over 40 years old and universally recognised and is reliable and trustworthy. The Test4 service is based upon testing for IgG antibodies, and the assertion that a positive result indicates a trigger food that causes an inflammatory response leading to a symptom.

There are many studies within the scientific community that support our process - those that are summarised below are but a select few of published articles related to our field. As with any scientific hypothesis there will be studies that support and do not support a position, and we invite our clients to not just consider the quantitative data that is usually provided but also the qualitatively measured human experiences and benefits of eliminating an IgG reactive food from the diet.

Introduction

A total of 150 outpatients with IBS were randomised to receive, for three months, either a diet excluding all foods to which they had raised IgG antibodies (enzyme linked immunosorbent assay test) or a sham diet excluding the same number of foods but not those to which they had antibodies.

Summary

A clinically significant improvement in IBS symptomatology was observed in patients eliminating foods to which they were found to exhibit sensitivity, as identified by an ELISA test for the presence of IgG antibodies to these foods.

Introduction

In this pilot study, 79 Crohn’s Disease patients and 20 healthy controls were examined for food specific immunoglobulin G (IgG). Thereafter, the clinical relevance of these food IgG antibodies was assessed in a double-blind cross-over study with 40 patients. Based on the IgG antibodies, a nutritional intervention was planned.

Summary

A nutritional intervention based on circulating IgG antibodies against food antigens showed effects with respect to stool frequency. Significant improvement in Crohn’s disease sufferers who followed diet removing food they showed sensitivity to (food sensitivity highlighted though IgG test). A clinically significant improvement in IBD symptoms was observed in patients eliminating foods to which they were found to exhibit sensitivity.

Introduction

A pilot study looked at two case studies of individuals with Asthma. The two subjects were put on an elimination diet after taking an IgG food intolerance test.

Summary

Both patients demonstrated substantial relief in symptoms of Asthma after following a IgG antibody guided elimination diet.

Introduction

There is now an increasing amount of reports on the gastrointestinal tract and its role in depression.

Summary

Where increased IgG concentrations to foods were found, the implementation of an elimination or rotation diet could be an effective method of reducing inflammation, thought to be a key cause of depressive disorders.

Depressive disorders may be linked to IgG food sensitivities, but further studies are required to confirm this theory.

Studies into the effects of IgG Antibodies have shown that they can influence things as varied as asthma and depression!
