The Food Reaction
Your Allergy Test
Never Found.
Standard allergy tests catch immediate IgE reactions. They miss the slower, far more common IgG-mediated sensitivities — delayed reactions that can take hours or days to surface and are almost impossible to trace without testing.

Two Very Different Reactions
Not all food reactions
are allergies.
Standard allergy testing only measures IgE — the immediate, histamine-driven response. Most food-related symptoms are driven by IgG — a slower, more diffuse immune reaction that unfolds over hours or days and rarely gets tested.
Immediate
Minutes to hours after exposure
Delayed
Hours to 72 hours after exposure
The Leaky Gut Link
IgG reactions may signal
intestinal permeability.
When the gut lining is compromised, larger food particles cross into circulation and trigger an IgG immune response. Elevated IgG food antibodies are frequently a sign of leaky gut — not just a food problem.
This is why food sensitivity testing pairs naturally with GI Effects stool analysis — one identifies which foods are triggering immune responses, the other reveals the underlying gut dysfunction that may be allowing them to.

What Gets Tested
Build the panel that fits your picture
Panels can be ordered individually or combined for a complete view of your immune-mediated food and environmental reactions.
IgG Food Antibodies
Commonly consumed foods plus total IgE — the most comprehensive delayed-sensitivity panel.
IgG Vegetarian Panel
Plant-based foods, grains, legumes, nuts, and seeds — ideal for vegetarian and vegan diets.
IgG Spices Panel
Common culinary spices — often overlooked as a hidden sensitivity trigger.
IgE Food Antibodies
High-priority IgE foods plus total IgE — identifies immediate allergic reactions.
IgE Molds Panel
Common environmental mold species — important for patients with respiratory or sinus symptoms.
IgE Inhalants Panel
Region-specific inhalant allergens across 18 North American geographic zones — including Arizona-relevant pollens.
IgG Bloodspot — At-Home Finger Stick
The IgG Food Antibodies panel is available as a simple finger-stick bloodspot. No clinic visit or blood draw required — collect at home and ship the same day.
Who This Is For
Symptoms that shift with food — but you can't find the pattern.
If your symptoms flare unpredictably and standard testing hasn't found a cause, delayed food reactions may be the missing variable.
Associated Conditions & Symptoms
IgG food sensitivity has been associated with all of the following
Pair With
Food sensitivities and gut health
are the same problem.
IgG reactions don't happen in isolation. A compromised gut lining is what allows food proteins to enter circulation and trigger an immune response in the first place.
Combining food sensitivity testing with the GI Effects Stool Analysis gives your practitioner the full picture — which foods are triggering reactions, and why the gut is allowing it to happen.
GI Effects® Stool Analysis
The most comprehensive stool test available — assessing digestion, gut inflammation, gut barrier integrity, and your complete microbiome from one at-home collection.

Important Information
IgG food sensitivity testing is a clinical screening tool — not a diagnostic test for allergy or disease. Elevated IgG antibodies indicate immune reactivity to specific foods; they do not diagnose IgE-mediated allergy, celiac disease, or any other condition. Results must be interpreted by a licensed healthcare provider in the context of your full clinical history and symptoms. IgG testing methodology is still an active area of research; clinical interpretation should account for current evidence.

Certain medications (corticosteroids, immunosuppressants, NSAIDs, chemotherapy) may influence antibody levels and affect test results — inform your practitioner of all current medications before testing.
