About Lettuce Allergy Test | Food Allergies in Urbana
Lettuce is a leafy green consumed in many forms, including romaine, iceberg, butterhead, and loose-leaf varieties. Although allergy to lettuce is uncommon, it is recognized in clinical literature, and reactions have been reported after eating the vegetable or handling it.
An allergy to lettuce is a form of food allergy. In sensitized individuals, the immune system identifies certain lettuce proteins as harmful and produces IgE antibodies against them. On later exposure, these antibodies can trigger the release of chemicals such as histamine, which produce allergy symptoms.
Reported symptoms of lettuce allergy include itching or tingling in the mouth, hives, swelling of the lips or face, stomach discomfort, and in rare cases more severe reactions. Some people react to raw lettuce but tolerate cooked lettuce, because heating can alter the proteins involved. Cross-reactivity is also possible; individuals with sensitivities to related plants such as mugwort or certain pollens may react to lettuce.
This test uses a blood sample to detect lettuce-specific IgE antibodies. A positive result indicates sensitization to lettuce proteins, but it does not by itself confirm that eating lettuce will cause symptoms. Diagnosis is made by a clinician who interprets test results alongside the person's history and, when appropriate, other evaluation.
