Corn allergy
Check and manage Corn allergy
A Maize/Corn IgG test checks antibodies linked to your immune response to corn. IgG means immunoglobulin G, a protein your immune system makes.
A high result can mean your body has reacted to corn. It does not prove a dangerous allergy by itself.
Monitoring matters because corn can hide in many foods and ingredients. A result can help guide safer food choices and a calmer talk with a clinician.

What is Corn allergy?
If corn makes you itch, swell, wheeze, or feel sick, your immune system may be reacting.
Corn allergy can cause mild symptoms or serious reactions. Testing and symptom tracking can help sort risk from noise.
Symptoms
- Hives, itching, or skin redness.
- Swelling of the lips, tongue, face, or throat.
- Stuffy nose, sneezing, or nasal swelling.
- Nausea, stomach pain, vomiting, or diarrhea.
- Coughing, wheezing, chest tightness, or trouble breathing.
- Dizziness, fainting, or signs of anaphylaxis in severe reactions.
Causes and risk factors
- Eating corn or foods made with corn ingredients.
- Exposure to corn starch, corn syrup, cornmeal, or corn oil in some products.
- A personal or family history of allergies, asthma, or eczema.
- Prior reactions after eating corn based foods.
- Cross contact during food preparation.
How it's diagnosed
A Maize/Corn IgG test checks antibodies linked to your immune response to corn. IgG means immunoglobulin G, a protein your immune system makes.
A high result can mean your body has reacted to corn. It does not prove a dangerous allergy by itself.
Treatment options
Management often starts with avoiding corn ingredients that trigger symptoms. A clinician may suggest antihistamines for mild reactions.
People at risk for anaphylaxis may need an epinephrine auto injector. Call emergency care for breathing trouble, throat swelling, or fainting.

Frequently asked questions
A high Maize/Corn IgG result means your immune system has made antibodies after exposure to corn. It may suggest a reaction pattern, but it does not confirm a severe allergy alone.
No. IgE tests are often used to assess immediate allergic reactions. IgG tests can show immune exposure, so results need clinical context.
Safe levels depend on the lab range, your symptoms, and your medical history. Review the result with a clinician, especially if symptoms happen after corn exposure.
Testing may help when symptoms repeat after corn or corn based foods. It is most useful when paired with a food and symptom log.
Yes, severe reactions can happen, though they are less common. Call emergency care for trouble breathing, throat swelling, fainting, or fast spreading symptoms.
Avoid foods and products that seem to trigger symptoms. Use medicines only as directed by a clinician or product label.
Do not make major diet changes without good reason. A clinician or dietitian can help avoid triggers while keeping meals balanced.
Bring your test result, food labels, and a symptom log. Note timing, serving size, symptoms, and any medicine used.
