In Home IgG Food Allergy Test with Candida

Availability: In stock

Quick Overview

This IN HOME Food Allergy Test is done using Dried Blood Spot Technology, so it’s done without a blood draw and almost painlessly. Tests for 93 Foods plus Candida. This IgG (immunoglobulin G) food allergy test is a useful guide for structuring elimination diets in many chronic conditions. People may continue to eat offending foods unaware of their potential effects. IgG antibodies provide long term resistance to infections and have a much longer half life than the traditional IgE allergy. The 93 foods tested in the IgG Food Allergy Test w/ Candida can identify problem food so it can be eliminated from the patient’s diet.

Dried Blood Spot In Home Blood Testing

Almost painless in-home testing. The IgG Food Allergy Test w/ Candida is available as a dried blood spot collection for patients and practitioners who can’t perform a blood draw. How it works:
1) A test kit with a Dried Blood Spot Card is shipped to you by mail
2) You ‘prick’ your finger with the enclosed kit, the same way a diabetic does.
3) You put the drops of blood onto the enclosed card and let it dry.
4) You mail the card back to the lab.
5) I send you your results! Easy.

Far better way to do blood tests than a traditional blood draw. You can even test children!

IgG (immunoglobulin G) testing is a useful guide for structuring elimination diets in many chronic conditions. Individuals with neurological, gastrointestinal, and movement disorders often suffer from IgG food allergies. These people may continue to eat offending foods unaware of their potential effects. IgG antibodies provide long term resistance to infections and have a much longer half life than the traditional IgE allergy. Symptoms may occur hours or days after the offending food has been eaten. The 93 foods tested in the IgG Food Allergy Test w/ Candida can identify problem food so it can be eliminated from the patient’s diet. This elimination of IgG positive foods can improve symptoms of irritable bowel syndrome, autism, AD(H)D, cystic fibrosis, rheumatoid arthritis, and epilepsy according to numerous clinical studies.

IGG Food Allergy Test Sample Results

Sample Test Results

The Great Plains Laboratory, Inc. has added Candida to the IgG Food Allergy 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. A wide range of disorders have been linked to Candida including autism, multiple sclerosis, depression, and chronic fatigue. Use of antibiotics, oral contraceptives, chemotherapy, and anti-inflammatory steroids greatly increase susceptibility to Candida.

Could you have Candida?

The Candida albicans scale has been updated to account for the observation that Candida-specific immunoglobulins are present in the specimens of virtually all individuals tested. The new scale is intended to provide a clearer indication of clinical significance and was 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

The Benefits of Testing

  • Helps determine if food reactions are contributing to physical or mental symptoms
  • Removal of highly reactive foods from the diet is a non-invasive, food-based therapy that often mitigates a patient’s symptoms
  • Research and clinical studies suggest food allergies identified by IgG testing can be a major contributing factor in many chronic health conditions
  • Food rotation and elimination diets can reduce stress on the immune system, lower gut inflammation, resolve food cravings, and reduce the potential for eating disorders

Testimonials

 

“I believe the Great Plains IgG Food Allergy Test is a phenomenal tool that I have implemented in my practice on a daily basis to help treat patients for a wide variety of symptoms like headaches, IBS, fatigue, abdominal pain, dermatitis, hair loss, joint pain, acne, thyroid disorders, and vitamin deficiencies. I believe I am a better physician due to this testing transforming my ability to properly diagnose and treat patients effectively.”

Total IgG versus IgG4 food allergy

Immunoglobulin G (IgG) is classified into several subclasses termed 1, 2, 3, and 4. IgGs are composed of two heavy chain–light chain pairs (half-molecules), which are connected via inter–heavy chain disulfide bonds situated in the hinge region (Figure 1). IgG4 antibodies usually represent less than 6% of the total IgG antibodies. IgG4 antibodies differ functionally from other IgG subclasses in their lack of inflammatory activity, which includes a poor ability to induce complement and immune cell activation because of low affinity for C1q (the q fragment of the first component of complement). Consequently, IgG4 has become the preferred subclass for immunotherapy, in which IgG4 antibodies to antigens are increased to reduce severe antigen reactions mediated by IgE. If antigens preferentially react with IgG4 antibodies, the antigens cannot react with IgE antibodies that might cause anaphylaxis or other severe reactions. Thus, IgG4 antibodies are often termed blocking antibodies. Another property of blood-derived IgG4 is its inability to cross-link identical antigens, which is referred to as “functional monovalency”. IgG4 antibodies are dynamic molecules that exchange half of the antibody molecule specific for one antigen with a heavy-light chain pair from another molecule specific for a different antigen, resulting in bi-specific antibodies that are unable to form large cross-linked antibodies that bind complement and thus cause subsequent inflammation(16). In specific immunotherapy with allergen in allergic rhinitis, for example, increases in allergen-specific IgG4 levels indeed correlate with improved clinical responses. IgG4 antibodies not only block IgE mediated food allergies but also block the reactions of food antigens with other IgG subclasses, reducing inflammatory reactions caused by the other IgG subclasses of antibodies to food antigens.

Immunoglobulin Structure Image

(Figure 1)In IgG1, IgG2, and IgG3 antigen binding sites are for the same food antigen. In IgG4 the antigen binding sites are for different antigens so that large immune complexes cannot be formed.

In IgG mediated food allergy testing, the goal is to identify foods that are capable of causing inflammation that can trigger a large number of adverse reactions. IgG1, IgG2, and IgG3 all are capable of causing inflammation because these antibodies do not exchange heavy and light chains with other antibodies to form bispecific antibodies. Thus, IgG1, IgG2, and IgG3 antibodies to food antigens can and do form large immune complexes or lattices that fix complement and increase inflammation. The presence of IgG4 antibodies to food antigens indicates the presence of antibodies to foods that will not usually cause inflammation even though high amounts of these antibodies do indicate the presence of immune reactions against food antigens. Testing only for IgG4 antibodies in foods limits the ability of the clinician to determine those foods that are causing significant clinical reactions that are affecting their patients. The importance of measuring other subtypes of IgG antibodies is highlighted in an article by Kemeny et al. (17). They found that IgG1 antibodies to gluten were elevated in all 20 patients with celiac disease but none of the patients had elevated IgG4 antibodies to gluten.

The IgG Food Allergy Test is available as both Serum and Dried Blood Spot.

  • Serum: 1 mL of in a gold-topped SST or in a royal blue-topped no additive tube.
  • Dried Blood Spot (DBS): Five full circles of dried blood on the protein saver card is required.

Please note that the elimination of a food prior to sampling will reduce the ability for our laboratory to detect antibodies (allergies) to that food.
