For qualitative/rapid kits, enter the gluten ppm detection level of the kit – for some kits, you may have the option to choose different detection levels, so please enter the level you used for this test.
For quantitative/exact ppm tests, enter the value of the lowest positive (non-zero) kit standard – please make sure to include the units of measurement for that standard (e.g., ppm gluten, ppb gliadin, etc.).
