Salad Vegetable Allergy Panel in Iowa

What this test measures

Raw vegetables can cause allergic reactions that range from mild mouth itching to skin or breathing symptoms. Celery and tomato are among the more frequently reported triggers, while spinach, cucumber, and lettuce are also recognized allergens. Because these foods are often combined in a single dish, pinpointing the cause can be difficult without testing.

The panel uses an allergen-specific IgE immunoassay on a blood sample. Each vegetable is tested separately, and the laboratory reports an antibody level and reactivity class. Blood testing is a convenient option when a person cannot pause antihistamines for skin testing or when multiple foods need to be checked at once.

A positive result indicates sensitization, not a confirmed allergy. Some people carry antibodies without ever reacting, and cross-reactivity between related plants can complicate the picture. Clinicians combine the panel with a detailed food and symptom history, and occasionally with supervised food challenges, before advising changes to the diet.
