To test for and identify sensitivities to peptides found in corn

Corn is a grain that is heavily used in gluten-free foods and, therefore, individuals following a gluten-free diet, who do not experience symptom improvement after fully eliminating gluten, may benefit from testing to determine if they also have an underlying corn sensitivity. Not only is corn widely prevalent in foods, but its various forms and derivatives are present in beverages, vaccines, medicines, supplements, and household items such as shampoo and body powder. The Corn Zoomer can definitively detect whether patients are sensitive to proteins in corn due to:

  • A combined detection of both IgA and IgG, which reduces the possibility of missing reactivity
  • Identification of peptides instead of proteins, reducing the possibility of cross-reactivity with similar species
  • Peptide-based microarray technique eliminates the requirement of testing different forms of corn (raw vs. cooked) and removes the false positives caused by cross reaction with pollens often seen in raw extracts
  • Improved understanding of unexplained symptoms associated with gastrointestinal, neurological, dermatological or behavioral disorders
  • Scale of reactivity (number of reactive peptide components) can give information of severity and help make decisions between rotation or elimination diets

Consider ordering the Corn Zoomer with a Wheat Zoomer to get the most comprehensive view of grain sensitivity, intestinal permeability (“leaky gut”), and make the most accurate nutrition recommendations for patients regarding eliminations of wheat, gluten, and corn. The Corn Zoomer also tests for and identifies specific antibodies to Corn Cry proteins, which are found only in genetically modified corn.

Markers Measured


Conditions and symptoms associated with corn sensitivity, occurring up to 72 hours after consuming corn include:

  • Bronchitis and asthma symptoms
  • Rashes (eczema)
  • Arthritis
  • Gas
  • Bloating
  • Fever
  • Fatigue
  • Diarrhea
  • Abdominal pain
  • Known intestinal permeability
  • Nausea and vomiting
  • Skin itchiness and redness
  • Joint pain
  • Muscle stiffness and swelling
  • Excessive sweating
  • Weakness



Will this test tell me if I am also reacting to corn starch and/or corn syrup?

Yes, the Corn Zoomer has an exclusive antibody panel which includes 13 major corn protein families and Cry Proteins used in genetically modified (GM) corn at the peptide level. The identification of peptides instead of proteins reduces the possibility of cross-reactivity with similar species. The peptide-based microarray technique eliminates the requirement of testing different forms of corn (raw vs. cooked) and removes the false positives caused by cross-reaction with pollens often seen in raw extracts. Also, since the test is at a peptide level, it will show every part of the corn plant (starch, syrup, etc) that has contact with the corn protein.

What type of corn is the Corn Zoomer testing?

The Corn Zoomer tests peptide-level antibodies to 13 different corn proteins. One protein, in particular, the corn CRY protein, is found specifically in genetically modified (GM) corn.

What type of patients would most benefit from the Corn Zoomer?

The Corn Zoomer is the only test on the market that offers peptide level antibody sensitivity to the entire corn proteome, including proteins specific for GMO corn. The Corn Zoomer can really be used for any patient that suspects corn sensitivity. Because of the structural homology between some corn proteins and gluten (alpha gliadin), this test may be particularly suitable for patients with refractory celiac or who have already eliminated gluten from the diet but are not seeing relief in symptoms.

What can I do if I test positive for antibodies on the Corn Zoomer?

Depending on your symptoms, history, and the severity of your results, you will likely be advised to follow a corn-free diet. This can be a difficult and frustrating process, but not impossible.
