Patients frequently confuse true food allergies with food intolerances. Understanding the distinct immunological pathways is vital for appropriate diagnostic selection.
IgE Allergy vs Non-IgE Sensitivity:#
- Type 1 IgE Hypersensitivity: Rapid onset (minutes to hours), involving mast cell histamine release. Tests: Total IgE & Specific IgE allergen panels.
- Enzymatic & Non-IgE Intolerance: Slow onset (hours to days), involving delayed gastrointestinal sensitivity or enzyme deficiencies (e.g. lactase deficiency).
QXL Diagnostics provides comprehensive specific IgE allergy profiles and 287-food IgG sensitivity panels with phlebotomy home collection across Bengaluru.
