Food Sensitivity & Immune Response Testing

Food sensitivities can be difficult to identify on your own because symptoms often appear hours—or even days—after eating certain foods. Unlike true food allergies, which trigger an immediate and potentially severe immune reaction, food sensitivities involve a delayed immune response that can quietly contribute to inflammation throughout the body.

Functional Medicine testing helps uncover these hidden triggers so we can reduce inflammation, restore gut health, and improve overall well-being.


What This Test Measures

Food Sensitivity & Immune Response Testing typically evaluates:

  • IgG-Mediated Immune Reactions
    Detects delayed immune responses to a wide range of foods, herbs, and food additives.
     
  • Complement Activation Markers
    Helps identify foods that trigger a stronger inflammatory process.
     
  • Food-Related Inflammation Patterns
    Highlights which foods may be contributing to symptoms such as brain fog, digestive issues, or skin problems.
     
  • Immune Reactivity to Common Proteins
    Includes testing for gluten, dairy proteins, eggs, soy, nuts, grains, and other frequently reactive foods.
     

Why This Matters

When your immune system is reacting to everyday foods, it can lead to chronic, low-grade inflammation. This may contribute to:

  • Bloating, gas, diarrhea, constipation
     
  • Fatigue, headaches, brain fog
     
  • Joint pain or muscle aches
     
  • Skin issues (acne, eczema, rashes)
     
  • Mood changes or difficulty concentrating
     
  • Weight fluctuations or difficulty losing weight
     

Identifying and removing reactive foods allows the gut lining to heal, calms the immune system, and often leads to significant improvements in energy, digestion, skin, and mental clarity.


Who Benefits From This Test

You may benefit from food sensitivity testing if you experience:

  • Chronic digestive symptoms
     
  • Persistent fatigue or headaches
     
  • Autoimmune conditions
     
  • Skin problems not responding to typical treatments
     
  • Mood swings or anxiety
     
  • Symptoms that fluctuate unpredictably
     
  • A history of antibiotic use or gut imbalance
     

What You Receive

  • A clear report showing which foods trigger an immune reaction
     
  • A personalized elimination and reintroduction plan
     
  • Targeted gut-healing strategies and supplementation
     
  • Follow-up support to help expand your diet safely over time
