What causes severe food allergies?
Patient: Hello my child has several food allergies (soy, peanuts/tree nuts, strawberries, wheat, eggs. When we last took her to her allergist who ordered labs all of her allergies were outrageously high though we make a conscious effort to keep her away from her allergens etc. What could possibly cause her blood test results to all be abnormally high? Doctor: Hello. I just read through your question.The tests only indicate that the allergy exists. It is not an indication of exposure. Patients with allegy who have no recent history of exposure will still test high.
