Biomarkers included

• Buckwheat: Buckwheat intolerance is a condition in which the body has difficulty digesting buckwheat, leading to digestive symptoms. Unlike a buckwheat allergy, which triggers an immune response and can cause severe reactions, intolerance is generally limited to gastrointestinal discomfort.
• Celery: Celery intolerance and allergy refer to different reactions some individuals may have to celery, a common ingredient in soups, salads, and snacks. A celery allergy is an immune system response to the proteins in celery, which can cause serious symptoms. In contrast, celery intolerance primarily affects the digestive system, leading to discomfort without involving the immune response.
• Mustard: Mustard intolerance is a condition that reflects difficulty in digesting mustard and mustard-based products. Unlike a mustard allergy, which triggers an immune system response and more severe symptoms, mustard intolerance primarily causes digestive discomfort and gastrointestinal symptoms after consumption.
• Peach: Stone fruit that can cause allergies ranging from oral allergy syndrome to severe reactions like anaphylaxis.
• Banana: Banana intolerance refers to a non-allergic reaction to bananas, a widely consumed and nutritious fruit. Unlike banana allergies, which trigger an immune response to specific banana proteins, intolerance usually stems from difficulties digesting certain components of the fruit.
• Sweet lupin: Sweet lupin intolerance is a digestive condition in which the body has difficulty processing sweet lupin, a legume commonly used in alternative food products. Unlike a sweet lupin allergy, which triggers an immune response, intolerance primarily causes gastrointestinal symptoms such as bloating or discomfort after consumption.

Follow the included instructions carefully before collecting your sample.

Frequently asked questions

Can this test help with bloating or digestive discomfort?

Yes. It may provide useful insight when digestive symptoms are difficult to connect to specific foods. Do I need to eat the foods before testing?

What is the difference between a food allergy and a food intolerance?

Unlike a food allergy (IgE), which causes an immediate and often severe reaction, a food intolerance (IgG4) is a delayed response. Symptoms can appear up to 72 hours after eating, making it very difficult to identify the culprit without laboratory testing.

Do I need to eat the foods I suspect I am intolerant to before the test?

Yes, for the most accurate results, you should maintain your normal diet. If you have already avoided a specific food for several months, your body may not be producing enough antibodies for the test to detect a reaction to that item.

How should I use my results to change my diet?

Once you receive your results, we recommend a temporary elimination diet. Remove the foods with high reactivity for 8 to 12 weeks, then slowly reintroduce them one by one while monitoring your symptoms to determine your personal tolerance levels.
