Understanding Lab Tests for Corn Allergy
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Corn allergy is an immune system reaction to proteins found in corn (maize) and corn-derived products. This condition can cause symptoms ranging from mild digestive discomfort to severe allergic reactions. Accurate diagnosis requires specialized blood testing to detect specific antibodies.
Recommended Test
Food Specific IgG Allergy (Pediatric) Panel
This comprehensive panel measures IgG antibodies specific to corn (maize) and other common food allergens. Elevated levels of corn-specific IgG antibodies indicate an immune response to corn proteins, which can help confirm a corn allergy diagnosis. This test is particularly valuable for identifying food sensitivities that may cause delayed allergic reactions.

Diagnosing Corn Allergy Through Blood Testing
Since corn is present in many processed foods and products, identifying a corn allergy can be challenging based on symptoms alone. Blood tests that measure specific antibodies to corn proteins provide objective evidence of an allergic response and help confirm the diagnosis.
Understanding Corn Allergy Symptoms
Corn allergy can manifest through various symptoms including skin reactions like rashes and hives, gastrointestinal symptoms such as nausea, diarrhea, and vomiting, and in severe cases, potentially life-threatening anaphylactic reactions. Testing helps confirm whether these symptoms are related to corn exposure.
Managing Corn Allergy
Once a corn allergy is confirmed through testing, management typically involves strict avoidance of corn and corn-derived ingredients. This includes reading food labels carefully, as corn products are found in many processed foods, medications, and even non-food items.
Important Considerations
