Food Print IgG Antibody Test (222 Foods)

FOOD PRINT IgG Ab Test – Comprehensive Food Reactivity Screening for 222 Proteins

The FOOD PRINT IgG Ab Test from Lab Tests Dubai is a comprehensive serum-based wellness panelthat measures IgG antibody levels against 222 common food proteins, including dairy, gluten, eggs, nuts, seafood, grains, fruits, and vegetables.

While IgG antibodies are not markers of food allergy, they may reflect immune exposure or delayed reactivity to certain foods—often associated with chronic digestive discomfort, fatigue, skin issues, and brain fog in sensitive individuals.

This test is designed for:

• Individuals with chronic, unexplained symptoms possibly linked to diet
• Those exploring elimination diets (e.g., for IBS, eczema, migraines)
• Patients seeking personalized nutrition insights under professional guidance
• Wellness seekers aiming to optimize gut health and energy levels

Using microarray technology based on ELISA, this advanced test delivers a detailed reactivity profile within just 5 days, helping nutritionists, functional medicine practitioners, and patients identify potential dietary triggers.

Available with home blood collection, Lab Tests Dubai ensures fast, accurate, and stress-free testing—so you can explore your food responses with confidence.

Why You Might Consider This Test

If you’re struggling with bloating, fatigue, headaches, or skin issues—and standard tests show no clear cause—this test could help guide a structured dietary trial.

You may consider the FOOD PRINT IgG Test if:

• You have chronic bloating, gas, or IBS-like symptoms
• You suffer from unexplained fatigue or brain fog
• You experience migraines, joint pain, or acne
• You’ve tried elimination diets without success
• You want a data-driven approach to personalized nutrition
• You’re working with a nutritionist or functional medicine practitioner

Important Note

This test does not diagnose food allergies or celiac disease. It screens for IgG-mediated immune reactivity, which some practitioners use to guide elimination and reintroduction protocols—not as a standalone diagnostic tool.

Always interpret results with a qualified healthcare provider.

Symptoms That May Indicate Food Reactivity

Consider the FOOD PRINT Test if you experience:

• Digestive Symptoms:

• Bloating, gas, or abdominal pain

• Diarrhea, constipation, or alternating bowel habits

• Nausea after certain meals

• Systemic & Neurological:

• Chronic fatigue or low energy

• Brain fog, poor concentration

• Headaches or migraines

• Skin & Inflammatory:

• Acne, eczema, or rashes

• Joint pain or stiffness

• Sinus congestion or post-nasal drip

• Metabolic:

• Difficulty losing weight despite healthy habits

• Cravings or blood sugar swings

These symptoms may be diet-sensitive—and this test helps prioritize foods for elimination trials.

Natural Production: What IgG Antibodies Reveal About Food Exposure

Immunoglobulin G (IgG) is the most abundant antibody in your blood, playing a key role in long-term immune memory.

When you eat a food repeatedly:

• Food proteins are absorbed in the gut
• Immune system may produce IgG antibodies as part of normal exposure
• Elevated IgG may indicate increased immune recognition—not necessarily intolerance

Key Medical Perspective

• Elevated IgG does not equal food intolerance (per AAAAI & ESPGHAN)
• High IgG may simply reflect frequent consumption (e.g., high IgG to wheat in bread-eaters)
• No proven causal link between IgG levels and symptoms

However, some integrative and functional medicine practitioners use IgG testing to:

• Identify foods to temporarily eliminate
• Guide reintroduction challenges
• Support gut healing protocols

This test should never replace diagnosis of allergies, celiac, or IBD.

What Happens If Food Sensitivities Are Ignored?

While IgG results require careful interpretation, chronic dietary triggers can contribute to:

• Persistent Gut Inflammation – worsening IBS, leaky gut
• Nutrient Malabsorption – due to chronic digestive stress
• Skin & Joint Inflammation – acne, eczema, arthritis
• Fatigue & Cognitive Issues – brain fog, low mood
• Poor Quality of Life – from unmanaged symptoms

The good news? Many food-related symptoms improve with:

• Structured elimination diets
• Gut microbiome support
• Personalized nutrition plans

This test helps start the conversation—not end it.

How to Prepare for the Test

To ensure accurate results:

• Continue your regular diet – do not eliminate foods before testing

• No fasting required

• Avoid immunosuppressants or high-dose steroids (can suppress immune response)

• Inform your doctor or nutritionist of:

• Current symptoms and diet

• Recent infections or gut treatments

• Use of probiotics or digestive enzymes

A serum blood sample is collected via standard draw—available at our labs or via home collection.
