IgG + Candida Food Antibody Test


We all eat a variety of foods each day, but it is very hard to work out which ones are doing us good, and which ones aren’t.

Sometimes some of the foods we eat can literally kill us.

How would you like to know – once and for all – what you can eat, and what you can’t?

IgG and Candida Connection


The report provided includes Candida albicans (a microscopic fungal organism and pathogenic yeast).

High levels of IgG antibodies to Candida have been found in patients who reported many symptoms of yeast overgrowth. Candida problems are caused when the benign yeast form of Candida albicans mutates to its fungal form and produces a buildup of toxins in the body.

Candida can overgrow areas of the intestinal mucosa resulting in numerous symptoms, including creating microscopic holes in the lining of the intestines, leading to what is commonly known as “leaky gut” syndrome. If Candida albicans proteins enter the blood, an inflammatory immune system response may be triggered.

A wide range of disorders have been linked to Candida overgrowth including autism, multiple sclerosis, depression, chronic fatigue, fibromyalgia, migraines, and irritable bowel syndrome. Immunocompromised patients with cancer or AIDS can have life-threatening complications if Candida enters the bloodstream, resulting in systemic candidiasis.

Use of antibiotics, oral contraceptives, chemotherapy, anti-inflammatory steroids, and diets high in sugar and starch increase susceptibility to Candida overgrowth.

Research has revealed a relationship between health of the gastrointestinal tract and overall well-being.

Imbalance between good and bad bacteria (dysbiosis) has been shown to worsen behaviour disorders, hyperactivity, aggression, and cause fatigue.

Evidence is mounting that dysbiosis impairs the immune system and contributes to food allergies, digestive disorders, nutritional deficiencies, and cognitive dysfunction. Using the IgG Food Antibody Test +Candida will help identify food intolerances and Candida sensitivity that may be creating a variety of problems for patients.

We may then recommend elimination of the identified foods and supplementation with various natural products that control Candida overgrowth and assist with healing of the gut. Depending on the levels of Candida and the severity of a patient’s symptoms, further testing may be recommended, including a Comprehensive Stool Analysis.


Candida Albicans Scale in the IgG Food Antibody Test

Candida-specific immunoglobulins are present in the specimens of virtually all individuals tested. The scale provided shows a clear indication of clinical significance and is established according to population percentile ranks, obtained from a random subset of 1,000 patients.

Specifically, the range of insignificant and low IgG values correspond to the first and second quartiles of the distribution, while moderate values denote individuals in the 51st to 97.5th percentiles. Those with an IgG value greater than the 97.5th percentile are considered to have a high concentration of Candida-specific immunoglobulins.

0-25th percentile:  insignificant
26th-50th percentile:  low
51st-97.5th percentile:  moderate
97.5th and higher:  high


What is IgG?

IgG is the major antibody found in serum. IgG’s are composed of two fragment antigen binding (Fab) regions that contain the antigen binding sites and the Fc region, which is responsible for most of the biologic activity of the antibodies.

An antigen is a substance that causes the immune system to produce an antibody that specifically reacts with it. IgG-mediated reactions to food antigens may be delayed by several hours or days, whereas IgE food antibody reactions are quite immediate.

Human IgG is separated into four subclasses denoted IgG1, IgG2, IgG3, and IgG4. Each subclass varies in abundance and biological function. IgG1 and IgG3 are predominantly responsible for antibody protection against reinfection. IgG2 antibodies are opsonic (marking a pathogen for ingestion and destruction) and develop in response to carbohydrate polysaccharide antigens. IgG4 molecules function as skin-sensitising immunoglobulins and are thought to block antibodies produced in response to chronic exposure to antigens.

Significance of Total IgG Versus IgG4

The goal of IgG-mediated food antibody testing is to identify foods that are capable of triggering a large number of adverse reactions. IgG1, IgG2, and IgG3 are all capable of causing inflammation. IgG1, IgG2, and IgG3 antibodies to food antigens form large immune complexes or lattices that activate complement proteins and increase inflammation. IgG4 antibodies that are present with food antigens will not usually trigger inflammation, though high levels of these antibodies does indicate the presence of immune reactions against food antigens.

While most laboratories only provide a measurement of IgG4 molecules, The Great Plains Laboratory provides a measurement of total IgG antibodies to various food-based antigens and Candida, a genus of yeast native to the GI tract. Testing for only IgG4 antibodies limits the ability of the clinician to identify those foods that may be causing significant clinical reactions in their patients. IgG4 antibodies usually represent less than 6% of the total IgG antibodies. The importance of measuring all subtypes of IgG antibodies is highlighted in an article by Kemeny et al.12 They found that IgG1 antibodies to gluten were elevated in all 20 patients with coeliac disease but none of the patients had elevated IgG4 antibodies to gluten.

The Benefits of Testing:


  • Helps determine if food reactions are contributing to physical or mental symptoms, and much more quickly than eliminating and then reintroducing each suspect food one-by-one over a period of time.
  • Removal of highly reactive foods from the diet is a non-invasive, therapy that often mitigates a patient’s symptoms.
  • Research and clinical studies suggest food allergies identified by IgG testing can be major contributing factors to many chronic health conditions.
  • Eliminating all identified food allergens after testing can reduce stress on the immune system, decrease inflammation (helping to heal “leaky gut”), resolve food cravings, and reduce the potential for eating disorders.



How is the Food Intolerance Test Done?

You purchase the IgG + Candida Food Antibody  Test just like to would any other product on Emed.

A test kit is sent out to you and it contains full instructions on how to obtain your sample. The sample is taken from a simple finger prick and only 5 drops of blood is needed.

Once the sample is completed, it is placed in a return address envelope for analysis – it couldn’t be easier!

Raw test data is sent to Emed and further evaluated.

An individual, comprehensive and in depth report is generated based on your case history outlining your test results and how to implement the changes to improve your health.

Emed will of course provide continuing online support to help you implement your specific plan.



Emed is Here for Ongoing Support

Once you have had the test rest assured that you will have access to ongoing online support from the Emed Team.

We are always there to help you implement the dietary changes and get the BEST results from the Test.

We genuinely want to help you achieve better health.

After all, that is what we are here to do!
