What is the G12 antibody?
G12 is able to recognize gluten in wheat, barley, rye and certain strains of oat (for more on oat toxicity, see question below). It is also uniquely well-suited to detecting gluten in hydrolyzed, fermented, or otherwise processed foods. In addition, the G12 antibody shows no cross-reactivity with soy or any other gluten-free matrices.
Emport is pleased to share some details from Biomedal regarding the G12 antibody, specifically developed to identify the 33-mer peptide of α- gliadin. Read more in our News post.

How sensitive are the GlutenTox tests?
According to the Codex Alimentarius Commission, the FDA and Health Canada, food can be considered “gluten-free” if it is made without gluten-containing ingredients and the amount of gluten present due to cross-contamination does not exceed 20 parts per million (ppm).

How do I test surfaces for gluten contamination, and what do the results mean?
Although it’s tempting to assign a ppm value for surface testing, this is technically impossible: after all, no one is eating the counter tops! Instead, surface gluten is measured in nanograms per square centimeter. The ppm value of a food that comes into contact with the surface would vary based on variables like volume (a little ball of dough or a big one?) and texture (dough vs an already-baked cookie?)
With GlutenTox, a negative surface test indicates that if a kilogram of absolutely gluten-free dough were kneaded on the surface, the dough would have

Are there items GlutenTox is not recommended for?
- Antioxidants, polyphenols, and tannins: Gluten found in matrices that are high in antioxidants, polyphenols, or tannins (for example cocoa or tea) can be difficult to extract. For this reason, it is possible that the amount of gluten present in these samples can be underestimated. If using GlutenTox Sticks, a separate polyphenol additive is available that can appropriately extract gluten from these matrices. Please note a positive result will always indicate the presence of gluten in the sample.
- Maggi – Seasoning – Arôme (liquid sauce): This seasoning sauce contains gluten as described by the manufacturer in its ingredients list. Note that its manufacturing process and other active ingredients are not suitable for GlutenTox Home. Consider this food as containing gluten.
- Soy Sauce: Naturally brewed soy sauce undergoes a fermentation process that often breaks down gluten to level close or below the detectable limit.
- Highly processed and complex matrices: Although GlutenTox Home and Pro tests have been successfully tested against a wide variety of highly-processed matrices, there may be some cases in which a more thorough extraction process is required to identify traces of gluten (for example, the multi-step extraction options available via GlutenTox Sticks). If you are planning to test a vitamin, supplement, medication, or other products that you feel may be highly processed, please contact us with more information about the specific item — we may recommend various modifications. In all cases, a positive test result always indicates the presence of gluten: to date no false positives have been found with G12.
- Items that are very high in silica: Large amounts silica can cause the extraction solution to “gel” in a way that can create challenges for the sample preparation process. These items often require special analysis in a laboratory setting. If you would like to test these items with GlutenTox, we suggest using half the amount of sample and double the number of drops as recommended in the manual.
- GlutenTox has been validated against some but not all personal care products. Because of the wide range of formulations and ingredients within personal care products, we recommend additional caution when testing shampoos, lotions, cosmetics, and other non-food items. While a positive result does always indicate the presence of gluten, false negatives are possible.
Can I test the oil in my deep fryer?
After 10 minutes, the test showed a negative result (only the blue control line appeared). But when I checked the test strip the next day, I noticed a faint pink line. What’s going on?

Can AlerTox Sticks kits detect allergens in fermented or hydrolyzed food?
As food processing breaks the proteins apart, there is a phase where they could be too small to get “caught” by the test but still big enough to cause damage to someone with an allergy.
