Why does your testing show the presence of gluten?

Regarding your question, the gluten test is only able to test the presence of gluten to a certain level. This test detects gluten when it is more than 0.0005% of the sample. Since there was is gluten found, the result is that there is less than 0.15mg per 30 grams. In other words, no gluten was detected, but the test is unable to say that there is 0% gluten, instead it can say there is less than 0.0005% gluten. The FDA standard for gluten-free is less than 20ppm, and our test shows there is less than 5ppm.
