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.
