IgG Food Intolerance blood test Canada

CanAlt IgG Food Intolerance Test

CanAlts IgG food intolerance test is a valuable tool to take out the guesswork and help patients to a better quality of life. The test uses microarray based ELISA technology that measures IgG antibody levels to over 200 different foods. The panel includes the foods that are common to food intolerances, such as dairy, eggs, wheat, soybean, and nuts as well as foods that can lead to an insensitivity, but may not be suspected, such as cola nut, rice, sunflower and sesame seeds. 

Strict control processes are in place to ensure the quality of the foods used for testing and there is no contamination. The food antigens are applied to a nitrocellulose pad for testing, then reagents are added through a series of steps that result in the development of a fluorescent colour that is proportionate to the amount of IgG antibodies present. Each food is tested in duplicate and each patient test is run with known standards and controls providing confidence in the accuracy of the results.

The report provides quantitative results that can be used to help design an elimination diet. Eliminate the foods with the highest results and start re-introducing the foods with the lower results first. 

Allergy or Food Intolerance

It is very important to understand the differences between an allergy and an intolerance. A food allergy is an immune reaction that results in the production of IgE antibodies. The reactions are usually immediate and symptoms can range from rashes, swelling, violent sickness, difficulty breathing and anaphylactic shock.

Food intolerances that are immune related result in the production of IgG antibodies and symptoms are usually not as severe and may not appear for several days. 

If you have a food allergy, it is important to continue avoiding that food, regardless of the test results obtained in the Food IgG Intolerance Test. This advice also applies if you have been diagnosed with Celiac disease or any other food related conditions such as lactose intolerance.
