Lactuca sativa Ab.IgE

This test detects IgE antibodies to lettuce, which can indicate a food allergy or oral allergy syndrome. Some people experience itching or swelling in the mouth when eating raw lettuce or other plant foods, especially if they have pollen allergies. IgE antibodies are produced when your immune system overreacts to a harmless substance. A positive result suggests lettuce may trigger allergic symptoms for you. This is distinct from a food intolerance and can help explain digestive or oral symptoms after eating lettuce.
