Corn is a grain that is heavily used in gluten-free foods and, therefore, patients following a gluten-free diet that 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 Vibrant 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 Vibrant Corn Zoomer also tests for identifies specific antibodies to Corn Cry proteins, which are found only in genetically modified corn.
