Food Intolerance Test for Children

Food Intolerance Test for Children:


Children under sixteen years of age will have to be assessed by the GP initially. If your doctor is of the opinion that a food intolerance test is appropriate for your child, the doctor will provide you with a referral letter for a food intolerance test and collect the child’s blood sample.

  1. Our laboratory will do the blood sample analysis & will return the results to the GP.

  2. The GP will manage the diet for your child.   


The parent can forward the referral letter plus blood sample to us for laboratory analysis. The test results will be returned to your doctor. Based upon these test results, your doctor can then make dietary recommendations.

The Science Behind Food Intolerance Testing


The test will measure the level of food specific, IgG antibody the immune system is producing against a panel of foods. A significantly elevated antibody response to any food indicates a loss of “tolerance” for that food. The normal situation is “tolerance” a state where the immune system is not activated.

Elevated levels of IgG antibodies to food indicate a breakdown in tolerance whereby the immune system is treating such food as potentially harmful. This process can drive low grade inflammation, a risk factor for many chronic conditions. Your doctor can use this test to guide the elimination diet for the child.

The Food Intolerance Test for Children


The laboratory can identify specific foods that are causing IgG antibody production. The food test for children is CE marked – in compliance with EU regulation for medical devices.

Important Notice:

  • We do not recommend the children's food test for kids under 3 yrs of age.

  • We do not test for allergies. Food allergy such a peanut allergy, is a serious medical issue and can only be treated in hospital or some specialist medical facility. Food allergy is associated with a fast, emergency reaction (anaphylactic) to some food. Food intolerance is totally different. It takes several hours or even days before any symptoms appear. Food intolerance is primarily associated with inflammation.

Childhood conditions which are strongly rooted in inflammation include:

  • Asthma

  • Bloating

  • Eczema

  • Acne

  • Constipation

  • Childhood obesity

  • Gut and digestive issues

  • Repeat middle ear infection

  • Urinary tract infections

  • Sinusitis

Is your child’s condition rooted in inflammation? Could food intolerance be the root cause of this inflammation? See this three-minute video below to find out more.

Your Child's Immune System


Upwards of 80% of your child’s immune system is rooted in their gut. Their immune system is intimately linked with the multitude of bacteria (microbiome) that reside within the child’s gut. The foods that they eat can play a crucial role in the disruption of their microbiome. Some children are more sensitive to this than others. But for children who are sensitive, food intolerance can have a profoundly negative impact on their health.


Case History (video below):


Little baby Aaron at three months of age suffered with severe projectile vomiting after every feed. Mother was breast feeding and the situation had become so severe that doctors prescribed surgery to stretch the muscle leading into the child’s stomach. Alarmed at the prospect, the mother contacted our clinic. Initially, the mother wanted the child to be tested. We explained that because she was breast feeding, the issue was with her milk. Her own food intolerance antibodies were coming through the milk and upsetting the baby. Within one week of mother changing her diet, the child returned to health with no more vomiting (see this video below).
