Understanding Lab Tests for Tomato Allergy
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
A tomato allergy is an immune system reaction that occurs when your body mistakenly identifies proteins in tomatoes as harmful substances. This can trigger various symptoms ranging from mild skin reactions to severe systemic responses. Blood testing is a reliable method to identify specific antibodies that indicate an allergic reaction to tomatoes.
Recommended Test
Food Specific IgG Allergy (Adult) Panel
This comprehensive panel measures IgG antibodies specific to tomatoes (f25) and other common food allergens. Elevated levels of tomato-specific IgG antibodies indicate an immune reaction to tomatoes, which may result in symptoms such as hives, skin rash, cough, vomiting, and in severe cases, anaphylaxis. This test provides valuable information for identifying trigger foods and developing an appropriate dietary management plan.

How Blood Tests Diagnose Tomato Allergies
When you have a food allergy, your immune system produces specific antibodies in response to the allergen. Blood tests can measure these antibodies, providing objective evidence of an allergic reaction. This testing is particularly valuable when symptoms are unclear or when multiple food sensitivities are suspected.
Understanding Your Results
Positive results for tomato-specific antibodies suggest that your immune system recognizes tomato proteins as allergens. This information can help you and your healthcare provider develop strategies to avoid trigger foods and manage symptoms effectively. The comprehensive panel approach also helps identify other potential food sensitivities that may be contributing to your symptoms.
