Vegan Foods

Adverse reactions to foods may be a source of considerable discomfort to patients.  The term food sensitivity refers to a condition where an individual reacts to an ingested food as though it were a toxin.  Foods that are normally considered healthy to most human immune systems, are considered a threat to those individuals with food intolerances.

Symptoms vary considerably and patients can respond in different ways to different foods.  Many people live with minor or major symptoms of adverse food reactions for years without ever suspecting the involvement of the immune system and the foods that trigger it.

Many individuals report improved weight control, more vitality and altogether a better quality of life, following implementation of dietary changes based on detection of food sensitivities and repairing leaky gut.

Exposure to foods within the same family may also evoke a sensitivity and should also be eliminated.  For example, sensitivity to grapefruit may increase the likelihood of a sensitivity to orange, or lemon (other members of the citrus family).

Sensitivities may also be hidden in other foods.  For example, sensitivity to eggs, should equate to caution in eating other foods that contain eggs, such as mayonnaise.

Additional $20.00 collection fee applies to this test.


Prepayment is required before blood collection. Patients can pay for their test at



Test Results:

Results are delivered to the referring practitioner via electronic download unless requested otherwise. Results can also be issued via hardcopy, fax or web based e-viewer.

Companion Tests:

  • Secretory IgA (sIgA)
  • Intestinal Permeability (IP)
  • Complete Digestive Stool Analysis (CDSA)

A deficiency of Secretory IgA (sIgA) may contribute to elevated IgG antibody levels to food antigens. Mucosal immunity plays an important role in food sensitivity and sIgA plays a major role in antigen handling and elimination. A lack of sIgA may permit the permeation of undigested food antigens into the bloodstream, thereby promoting immune complex formation and circulation for an uncertain period of time. The sIgA test is therefore highly recommended in conjunction with the IgG FoodPrint testing.

Increased Intestinal Permeability may also be an important contributing factor in the development and exacerbation of food sensitivity. As Intestinal Permeability test may provide valuable information as to whether this is an important underlying cause.

Similarly, poor digestive function and imbalanced gut flora may create an environment that facilitates food sensitivity. A Complete Digestive Stool Analysis (CDSA) may therefore be useful in terms of understanding the underlying causes of this condition.
