Chronic low-grade gut inflammation, irritable bowel symptoms, skin flare-ups, and unexplained lethargy often trace back to delayed non-IgE food sensitivities rather than immediate acute Type-1 allergies. While classical IgE antibodies trigger instant histamine reactions (such as hives or anaphylaxis), food-specific Immunoglobulin G (IgG) antibodies form circulating immune complexes that manifest 24 to 72 hours after consuming culprit foods.
Why 287-Food Microarray IgG Testing Leads Precision Clinical Nutrition#
- High-Throughput Antigens: Evaluates 287 individual food items spanning dairy, gluten, grains, seafood, spices, nuts, and fruit proteins on advanced microarray platforms.
- Quantitative Staining Ratios: Pinpoints mild, moderate, and high antibody reactivity for structured elimination diets.
- Clinical Guidance: Reviewed by consultant biochemists to ensure nutritional adequacy during trial elimination and reintroduction phases.
At QXL Diagnostics, every food sensitivity report includes personalized dietary guidance validated by senior laboratory consultants.
