When the shamal blows — typically late spring into early summer — fine dust hangs in the air for days, and a predictable wave of blocked noses, itchy eyes and coughs follows. A surprising number of people respond by ordering a food intolerance panel, because the symptoms are vague and food is the easiest suspect. Most of the time the culprit is environmental: dust mites thriving in year-round air conditioning, mould spores in humid coastal months, and pollen from ghaf, mesquite and date palms that peaks in spring.
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.
