Description
Understanding the Food Sensitivity Test
Unlike food allergies, reactions from food sensitivities may cause symptoms hours or even days after eating the offending food.
This test evaluates IgG antibodies in your blood related to 222 common foods. Elevated antibodies may indicate that you could be sensitive to that food. This test does not detect allergic reactions to foods, lactose intolerance, or celiac disease.
Related symptoms include:
- Fatigue
- Bloating
- Gastrointestinal stress
- Headaches
- Migraines
- Stomach pain
Test Preparation Requirements
It is important to avoid known food allergies and foods that you know make you feel poorly. Consuming a broad diet prior to conducting a food sensitivity test, while safely avoiding known potentially life-threatening foods, will provide the best insight into which foods may be problematic. If you suspect a severe allergic reaction to any food, do not eat it and contact your healthcare practitioner.
A simple finger stick to collect a few drops of whole blood is all that is required.
What Do the Results Mean?
Food sensitivity testing helps you discover which foods in your diet may be a source of symptoms. This test evaluates your immune system’s reactivity to foods, which helps guide a temporary elimination diet to improve symptoms and overall health.
A simple traffic light system shows which foods have an elevated antibody reaction and which foods may be freely eaten. The report shows U/ml for each food, indicating the level of antibody reactivity detected.
Use of immunosuppressant medications may affect the results. Never discontinue any prescription medications without consulting your doctor first.
If you are experiencing symptoms related to a specific food at any level, that is your threshold for tolerance. We recommend temporarily removing the food to allow symptoms to resolve before reintroducing it into your diet.
General Recommendations
- RED: Elevated ≥30 U/ml – High antibody reaction detected. Eliminate these foods for at least 3 months and substitute with normal (green) foods from the same group. With many elevated foods, eliminate the top 5 contributing most to immune response and rotate remaining positive foods.
- YELLOW: Borderline 24–29 U/ml – Moderate antibody reaction detected. Reduce and rotate these foods, limiting to twice per week for at least 3 months. Substitute with normal (green) foods. See the Patient Support Guide for rotation diet instructions.
- GREEN: Normal ≤23 U/ml – No significant reaction detected. These foods can be eaten without restriction unless previously caused an adverse reaction. Avoid foods with known IgE Type 1 allergy even if showing as normal.
Note: If symptoms persist after 3 months on this diet, they may not be due to food IgG sensitivities. Seek further medical advice.
Reintroduce one food at a time after 3–6 months and monitor for symptoms. If symptoms return, cease the food and reintroduce after 3–6 months. Remove foods permanently if symptoms continue.
This test alone cannot confirm food sensitivity or intolerance. Follow up with a licensed healthcare professional to review results along with your medical history, symptoms, diet, and other tests before making nutritional changes.
