Details about Food Sensitivity Test with Interpretation
What is the Food Sensitivity Test with Interpretation?
The Food Sensitivity Test with Interpretation is a laboratory blood test that measures IgG antibody responses to a broad panel of commonly consumed foods and there are 220 food products tested. Unlike allergy tests that detect immediate immune reactions (IgE), this test evaluates delayed immune responses, which may contribute to ongoing or unexplained symptoms.
The test covers multiple food categories:
Dairy & Eggs
• Cow’s milk
• Cheese
• Yogurt
• Egg white and egg yolk
Grains & Gluten-Containing Foods
• Wheat
• Barley
• Rye
• Oats
Meat & Fish
• Chicken
• Beef
• Pork
• Tuna
• Salmon
Nuts & Seeds
• Almond
• Peanut
• Hazelnut
• Sesame
Fruits & Vegetables
• Tomato
• Banana
• Apple
• Citrus fruits
• Potato
Other Common Foods
• Soy
• Yeast
• Coffee
• Chocolate
By identifying immune responses to these foods, the test helps uncover potential dietary triggers that may contribute to symptoms.
Why do I need this test?
Food sensitivities can cause symptoms that appear hours or even days after eating, making them difficult to identify without testing.
You may benefit from this test if you experience:
• Bloating or digestive discomfort
• Fatigue or low energy
• Headaches or migraines
• Skin issues such as eczema or acne
• Joint discomfort
• Brain fog or concentration problems
• Unexplained inflammation
• Suspected reactions to foods
The results can help guide elimination diets and nutritional adjustments more precisely.

Follow these guidelines for accurate results
Sample Timing
Where possible, attend your blood test between 7am and 12pm. Please wait until any short-term illness or infection has fully resolved before testing. Avoid intense exercise for 24–48 hours beforehand, as this can affect certain markers.
Fasting & Hydration
Fasting is not always required, but some tests may recommend it. If fasting is advised, avoid food for 8–12 hours before your appointment and drink water only. Stay well hydrated, as this helps with sample collection and accuracy.
Medications & Supplements
Continue prescribed medications unless advised otherwise by your clinician. Avoid vitamin, mineral, or biotin supplements for at least 24–48 hours before your test, as these can interfere with results. If you are unsure about any medication or supplement, please let us know before your appointment.
Hormones & Menstrual Cycle
For hormone-related tests, timing within your menstrual cycle may be important. If relevant, follow any specific guidance provided on your test page.
If you have any questions or special circumstances, our team is happy to advise before your appointment.
