Twenty Food IgE Panel in Arizona

What this test measures

This panel measures allergen-specific immunoglobulin E against twenty common foods in a single blood draw. Typical targets include milk, egg, peanut, wheat, soy, codfish, shrimp, crab, walnut, almond, sesame, and corn, along with other frequently eaten ingredients. Reporting each food separately helps identify which items stand out. The panel is a screening tool, and sensitization does not always mean a food causes symptoms.

A blood sample is collected by venipuncture at a partner laboratory and analyzed with immunoassays. Each food-specific IgE result is reported in kilounits per liter with an IgE class, and total IgE may be included for context. Some food proteins share structures with pollen or other foods, so cross-reactive patterns can appear. That is one reason results are interpreted together with a clinical history rather than in isolation.

People order this panel when multiple food reactions are suspected, when symptoms are vague, or when they want broad information before an elimination plan. It is also used by families exploring common childhood food allergens. A qualified healthcare provider should guide interpretation, because panel results can show sensitization to foods that are tolerated without any symptoms.
