IgG Food Sensitivity Testing

Sound Familiar?
Your Food Could Be the Culprit.
Hidden sensitivities can drive symptoms you'd never connect to your diet.
Bloating, gas, and digestive discomfort after meals — but you can't pinpoint the cause
You've tried elimination diets but can't figure out what's triggering your symptoms
Skin issues like eczema, acne, or rashes that won't clear up
Brain fog, headaches, or joint pain that seem connected to eating
You feel inflamed and puffy but don't know why
Food Sensitivities vs. Food Allergies
Food allergies cause immediate, often severe reactions (think hives, swelling, or anaphylaxis). Food sensitivities are different — they trigger delayed immune responses (IgG-mediated) that can take hours or even days to appear, making them extremely difficult to identify on your own.
These hidden sensitivities can cause chronic, low-grade inflammation throughout your body, contributing to digestive issues, skin problems, headaches, fatigue, joint pain, and mood changes. IgG food sensitivity testing takes the guesswork out by identifying exactly which foods are triggering your immune system.

FAQ
Common Questions
IgE testing identifies true food allergies with immediate reactions. IgG testing identifies delayed food sensitivities that cause chronic, low-grade inflammation. Both provide valuable but different information.
Our panels typically test 96+ common foods including dairy, grains, fruits, vegetables, proteins, nuts, and spices.
Not necessarily. After a structured elimination period (typically 6–12 weeks), many foods can be carefully reintroduced. The goal is to reduce inflammation and allow your gut to heal.
Many patients notice improvements in bloating, energy, and mental clarity within 2–3 weeks of eliminating their top reactive foods.
Yes. As gut health improves and inflammation decreases, some sensitivities may resolve. Retesting after 6–12 months can help guide long-term dietary decisions.
