  • IgG Food Sensitivity Test with Candida & YeaST

IgG (immunoglobulin G) testing is a useful guide for structuring elimination diets in many chronic conditions. Individuals with neurological, gastrointestinal, & movement disorders often suffer from IgG food sensitivities. These people may continue to eat offending foods unaware of their potential effects. As immunological reactions, IgE food allergy causes the release of histamine, producing an immediate hypersensitivity reaction, in which symptoms appear within minutes or hours. In contrast, food sensitivity is a non-IgE allergy characterised by the measurement of IgG antibodies specific to antigenic food proteins. This IgG food allergy is a delayed hypersensitivity reaction in which symptoms appear anywhere from hours to days after eating the offending food.

This test has added Candida to the IgG Food Sensitivity Test. Candida problems are caused when the benign yeast form of Candida albicans mutates to its fungal form. Candida can take over sections of the intestinal wall causing numerous symptoms. As it grows out of balance it produces toxins that create holes in the intestinal lining, leading to leaky gut syndrome. After entering the blood, Candida albicans causes an inflammatory immune system response. Use of antibiotics, oral contraceptives, chemotherapy, & anti-inflammatory steroids greatly increase susceptibility to Candida.

The Gastrointestinal Microbial Assay Plus (GI-MAP) was designed to assess a patient’s gut biome from a single stool sample, with particular attention to microbes that may be disturbing normal balance & may contribute to changes in the gastrointestinal (GI) flora or illness. It detects parasites, pathogenic bacteria, commensal bacteria, opportunistic pathogens, fungi & more by targeting the specific DNA of the organisms tested. 


Zonulin has been identified as a key biomarker for intestinal permeability, which has been associated with coeliac disease, non-coeliac gluten sensitivity (NCGS), and other GI & systemic conditions, such as 'leaky gut'.
