Our Children’s Food Intolerance Test measures your child’s IgG antibody levels for 89 everyday foods and ingredients using a finger-prick blood sample collected at home. The digital report gives you a clear view of their measured results and information to discuss with a qualified nutritionist.

Great value for families, every test includes a 30-minute consultation with a qualified nutritionist. You can ask questions about your child’s results, discuss any food-related concerns and get guidance on appropriate next steps.

If a dietary plan is agreed following the consultation, your nutritionist can provide a formal guidance letter for your child’s school, nursery or club, explaining any foods being avoided.

Who is this test for?

If your child aged 2-17 has ongoing symptoms and you suspect everyday foods could be playing a role, our Children's Food Intolerance Test can help identify potential IgG reactions to 89 everyday food and drink ingredients. It provides valuable insights to help you make more informed dietary choices for your child.

Food intolerances can affect every child differently, and symptoms often develop gradually over time. Results should always be considered alongside your child's symptoms and, where appropriate, advice from a healthcare professional.

Expert insight, clearer next steps

IgG food intolerance testing measures food-specific IgG antibodies in the blood, helping to identify foods that may be worth exploring as part of a structured elimination and reintroduction approach.

For parents, understanding which everyday foods may be linked with their child’s symptoms can provide a useful starting point for making more informed dietary decisions.

“When a child is experiencing ongoing digestive discomfort, low energy or other unexplained symptoms, it can be difficult for parents to know where to start.”

“Food intolerance testing can provide useful insights into how their child may be responding to different foods, giving families a clearer direction for an elimination and reintroduction approach.”

“The important part is what happens after the test. With the right guidance and support, parents can use their child’s results to make considered dietary changes while ensuring their nutritional needs remain at the heart of the process.”

Medical Director | MBBS, DRCOG, DFFP, MRCGP

Understanding the differences between food reactions

Allergy, intolerance, and sensitivity are often used interchangeably — but they’re not the same. Each involves a different type of reaction in your body, and understanding the difference is key to managing your symptoms effectively.

Food intolerance

Food intolerances trigger a different kind of immune response than food allergies.

Although the exact science isn’t fully understood, research suggests that IgG antibody reactions may play a role in symptoms for some people. When combined with an elimination diet, IgG testing can help identify foods that may be causing inflammation-related issues.

Unlike allergies, which cause immediate reactions, symptoms of food intolerances often show up hours or even days later — making it much harder to connect the dots without testing.

Common symptoms reported by our customers include:

• Headaches
• Bloating
• Stomach pain
• Indigestion
• Gastrointestinal discomfort

Food allergy

Food allergies trigger an immediate immune reaction involving IgE antibodies. When someone eats a food they’re allergic to, their immune system releases histamine, which can cause symptoms like:

• Swelling
• Itching
• Hives
• Trouble breathing
• In severe cases, anaphylaxis

This is why many allergy medications are called antihistamines — they work by blocking the effects of histamine.

For example, tree nut allergies (to foods like hazelnuts, walnuts, or macadamia nuts) can cause severe, life-threatening reactions. Anaphylaxis can occur within minutes of exposure, potentially leading to a dangerous drop in blood pressure or airway swelling that makes it hard to breathe.

Sensitivities

Food sensitivities happen when your body struggles to process certain foods, often because they are difficult to break down in the digestive system.

Unlike food allergies or intolerances, sensitivities don’t involve the immune system. Instead, they mainly affect how well your digestive system can handle specific foods.

A common example is caffeine sensitivity.

Caffeine is found in coffee, tea, and energy drinks. Some people break it down more slowly, which can lead to symptoms such as:

• Jitters or restlessness
• Rapid heartbeat
• Trouble sleeping
• Stomach discomfort

While food sensitivities aren’t typically dangerous, they can still cause significant discomfort and affect your daily wellbeing if left unmanaged.
