Tomato Antibody Test in Alaska

What this test measures

Tomato belongs to the nightshade family, and its proteins can act as allergens in sensitive people. Reactions may include oral itching or tingling, hives, eczema flare-ups, abdominal discomfort, or in rare cases more serious symptoms. Cooking can change some tomato proteins, so reactions vary depending on whether the food is raw or cooked.

The test detects tomato-specific IgE in serum using a laboratory immunoassay. It provides a quantitative level and often a reactivity class. Because reactions to raw and cooked tomato can differ, and because pollen allergy can cause related oral symptoms, clinicians interpret the result together with a detailed food and symptom history.

A positive test shows the immune system recognizes tomato proteins, but it does not predict how severe a reaction will be. Some people test positive without symptoms, and others react mainly during certain seasons. A qualified healthcare provider, sometimes with an allergist, can assess the findings and discuss appropriate next steps.
