Description
IgG Food MAP with Candida + Yeast
What does this test measure?
This blood test, which can be done using serum or a dried blood spot, measures
IgG antibodies against a wide range of approximately 190 food antigens, as
well as common yeasts such as Candida albicans and brewer’s yeast
(Saccharomyces). Unlike IgE allergies that trigger immediate reactions, IgG
food reactions are classified as delayed hypersensitivities. These reactions
may contribute to chronic symptoms like digestive issues, migraines, and skin
conditions such as eczema, although this view remains somewhat controversial
in mainstream medicine.
The inclusion of Candida and yeast IgG levels helps determine if the immune
system has an elevated response, which might indicate yeast overgrowth in the
gut. The purpose of this test is to identify foods that provoke an immune
response (via IgG) that could lead to low-grade inflammation in the body.
Who is this test most suitable for?
- People with diets heavy in certain foods (e.g. daily dairy or wheat – might
develop IgG to those) - Individuals who suspect foods cause them issues but can’t pinpoint which
(this test can give clues) - Chronic illness patients experimenting with elimination diets
- Those following gut-healing regimens (like leaky gut protocols) to see what
to eliminate
Clinical Use
Clinically, practitioners use these results to tailor elimination diets – for
example, if someone has high IgG to dairy, gluten, and eggs, they might remove
those foods for a period to see if symptoms improve. The yeast IgG part helps
indicate if antifungal treatment might be needed. This test is often used in
integrative and naturopathic practice for patients with IBS, migraines,
fibromyalgia, autism, ADHD, skin rashes, joint inflammation, etc. where an
underlying food sensitivity is suspected. It provides a personalized list of
reactive foods (graded by antibody levels) to guide dietary changes.
