The Food Sensitivity Profile 1 measures the body's IgA and IgG response to 96 commonly consumed foods antigens via specific antibody-to-antigen recognition.
An antibody-based food sensitivity test can help prioritize the necessary foods to create a customized elimination nutrition plan. This test should be considered for patients who might be suffering from delayed reactions to certain foods. Removing foods the body has produced antibodies to will improve or eliminate symptoms.
The physician should consider that if IgA antibodies (produced by the intestinal mucosa) are elevated to a particular food antigen, it may indicate an immune response to mucosal irritation or damage.
On the other hand, elevated IgG antibodies may indicate exposure to this food in the bloodstream, suggesting that the body is producing antibodies. IgG antibodies can be downstream of intestinal permeability. These are likely correlated with more systemic immune responses (brain fog, fatigue, skin, migraines, among others).
Food sensitivity symptoms can easily overlap with other common medical diagnoses. Therefore, it’s vital to rule these sensitivities out while looking for a root cause. The most common symptoms associated with food sensitivities are:
The test uses an array of 209 commonly consumed food antigens offering a very specific antibody-to-antigen recognition.
This panel provides the options to measure a patient’s IgG, IgA, IgG subclass 4, and C3d reactivity to food antigens.
Testing IgA antibodies gives the practitioner additional information on foods that may be causing mucosal damage.
The physician should be mindful of the difference between food allergy and food sensitivity. A food allergy (type I hypersensitivity or immediate reaction) is usually mediated by an IgE-specific antibody which is not measured on the test. IgG and IgA antibodies are indicative of food sensitivity.
This is a serum based test and requires a phlebotomy appointment. There is also an at-home blood spot version of this test.
This test cannot be ordered for patients under 2 years of age.
The Food Sensitivity Profile 1 measures the body's IgA and IgG response to 97 commonly consumed foods antigens via very specific antibody-to-antigen recognition. This is the serum version of the test. It is also available as a blood spot test. This test cannot be ordered for patients under 2 years of age.
