How does the test work?

Often people will consume a lot of their favorite foods, which may result in a higher level of IgG antibodies, although they may have no symptoms and this is normal. These antibodies will form antigen/antibody complexes against the partially digested food. An efficient immune system (i.e. macrophages) will clear these complexes before they are deposited in tissues.


The Health Food Intolerance test is carried out on a blood sample collected from a finger-prick into blood collection tube. The sample is stable for 14 days, allowing for transportation to our testing facility.

In our test, controls are tested with each patient and each food is tested in duplicate, increasing the reliability of the test results.

Health Food Intolerance Reports

A numerical result, provided in U/ml, is provided for each food. This provides a comparison of the antibody reactivity associated with each food and aids the practitioner to devise an optimal dietary regime based on food antibody level.

The Health Food Intolerance report provides two report formats:
  • Results are provided by food group (e.g., Dairy/eggs, Fruit)
  • Foods are categorized as Elevated, Borderline or Normal, based on the numerical result. Foods under the Avoid column should be avoided for a period of 2 – 3 months after which time they can be re-introduced. Intake of foods in the Borderline category should be moderated. If symptoms return when a particular food is re-introduced, the food should be removed from the diet.
