Should I get a food allergy test or a food intolerance test?
the desk replies — If reactions involve hives, swelling, vomiting or breathing difficulty, you need IgE allergy testing and a doctor, because true allergy can be dangerous. IgG intolerance panels are widely sold but are not considered diagnostic by most allergy bodies — raised IgG often just reflects what you regularly eat. Use them, if at all, as a starting point for a clinician-supervised elimination diet.
