About this test
The Corn Allergy Test measures immunoglobulin E (IgE) antibodies against corn, also called maize. This test is for corn as a food rather than corn pollen. Corn is used in many foods and food ingredients, so reactions may occur after eating products that contain it. Symptoms can include hives, itching, or digestive upset. This blood test helps assess whether your symptoms may be linked to corn. Results are interpreted with your history and the foods you have eaten.
What this test measures
- Corn (Maize)-specific IgE Measures IgE antibodies that react to corn, also known as maize, proteins.
Who this test may be right for
- People who develop hives, itching, or swelling after eating corn or corn-containing foods.
- Individuals with a suspected food allergy who want to check corn specifically.
- People who notice symptoms after products that may contain corn ingredients.
- Anyone with a history of food reactions who wants to broaden their allergen profile.
- Caregivers investigating reactions in children after corn-containing meals.
Before your visit
- No fasting is required.
- Continue your usual medications unless a healthcare provider advises otherwise.
- Pause antihistamines before testing only if your provider instructs you to, as they may affect some allergy results.
- Note which corn-containing products and symptoms you have experienced.
Understanding your results
The report shows the level of corn-specific IgE antibodies. A higher level may suggest sensitisation to corn as a food, while a low or undetectable level makes allergy less likely. Because corn and its derivatives appear in many processed foods, your provider will relate the result to the products you have eaten. This test targets corn as a food and does not measure corn pollen allergy. Discuss any positive or unexpected result with a healthcare provider before changing your diet.

Questions people ask
What does a corn-specific IgE result mean?
It shows whether your immune system has produced IgE antibodies that recognise corn, or maize, proteins. An elevated level may indicate sensitivity but does not confirm that corn caused your symptoms.
Does this test check for corn pollen allergy?
No. This test measures IgE to corn as a food, not to corn pollen. If pollen allergy is a concern, your provider can recommend a separate test.
Where is corn found in food?
Corn and corn-derived ingredients are used in many foods, including sweeteners and starches. Reading ingredient labels can help you track exposure.
Do I need to avoid corn before testing?
No. The test measures antibodies already present in your blood, so avoidance and fasting are not required.
