Gluten Free Watchdog recently tested weighed samples of cream cheese, cream cheese spread, yogurt, and soft cheese for gluten using a Nima Sensor. This testing was done due to complaints received about various products testing gluten found when tested with a Nima. When the weight amount tested was the amount recommended by the original Nima team, all results were a “smile.” This means no gluten was detected. However, as the weight amount of the sample tested increased, smiles gave way to gluten found results which gave way to “no test result” readings. Products were also tested with the sandwich and competitive R5 ELISAs. All samples tested below the lower limit of detection for both assays. Ideally, Nima users should be advised on the weight amount of product to test and samples should be weighed before testing. The complete results will be posted publicly at a later date.  In the meantime, subscribers to Gluten Free Watchdog can view the special report after login at–nima-sensor-test-results/1199.

    Thank you for this important clarification.

    Not sure if it’s related, but… One thing to remember is, if it’s a packaged food, it may be gluten free at one serving, and not gluten free at below 20ppm if you have 3 servings. And that happens a lot. Always check to see if the servings make sense for how you plan to eat the product.

    This is part of the reason I have a gluten detection dog. I don’t want to risk one sample safe but the product as a whole is not.

      Curious, How did you go about getting a gluten detection dog? Thinking of trying to get one for my 15 year old daughter, just not sure where to start. Thanks in advance.
