Allium cepa Ab.IgE

This test detects IgE antibodies against onion in your blood, indicating a potential allergic reaction to this common vegetable. Onion allergies are uncommon but can cause oral itching, throat swelling, or digestive symptoms. People with birch pollen allergies may experience cross-reactivity with raw onion proteins, while cooking often breaks down these proteins, making cooked onions safer. A positive result helps you understand your reaction triggers and guides your food choices and meal preparation.
