IgG Food Sensitivity Testing

Take the Guesswork Out of Your Diet

Food sensitivity is not a disease but may play a role in causing disease or worsening certain symptoms. Symptoms associated with food sensitivities develop slowly over time and can create inflammation. The RMA FST™ IgG Food Sensitivity Test can help identify potential food sensitivities and take the guess work out of your diet

There is a growing body of evidence to support the clinical benefits of eliminating IgG reactive foods from the diet.

In an IgG reaction, the IgG antibodies bind to food antigens creating antibody-antigen complexes. These complexes are normally removed by immune system cells called macrophages. However, if complexes are present in large numbers and the reactive food is still being consumed, the macrophages cannot remove them quickly enough. The food antigen-antibody complexes accumulate and can be deposited in body tissues. Once in tissues, these complexes can trigger inflammation, which may be responsible for a wide variety of symptoms.

Test Overview

The RMA FST™ IgG Food Sensitivity test has three different options for testing IgG antibodies




Antibody levels are measured via an ELISA (Enzyme-Linked Immunosorbent Assay) microarray method. For an ELISA test, food antigens must first be chemically bonded to a site within a gel pad. Each of these sites has the antigens of one specific food. More than 220 foods can be tested on a single gel pad for any given patient. A measured amount blood serum of the patient is placed on the pad and then treated with a series of chemical solutions. Eventually a colour develops at each site and the intensity of the color is measured by a high-resolution scanner. The intensity of the colour is proportionate to the amount of antibody in the blood specific to that food antigen.
