shamal season: telling dust allergy from food intolerance
The tests are genuinely different things. Allergy testing measures IgE antibodies against specific triggers — dust mites, moulds, pollens, and true food allergens — and is the medically established tool. Food intolerance panels usually measure IgG antibodies, and here honesty matters: IgG panels are popular and widely sold, but most allergy bodies internationally do not consider raised IgG a diagnosis of anything, since it can simply reflect what you regularly eat. They can be a starting point for a supervised elimination diet, but they are not proof of intolerance and never a test for true allergy.
If your reactions involve swelling of the lips or throat, hives, vomiting or any breathing difficulty, that is potential true allergy territory and it belongs with an allergist or emergency care, not a home kit. Where home collection shines is the environmental IgE panel during shamal season: a nurse draws one sample at home, the lab screens a broad set of regional triggers, and you and your doctor get an evidence-based answer about whether it is the dust, the mites or genuinely the dairy.
