Gluten-Free Quaker Oats & Testing with the Nima Sensor, R5 ELISA, & G12 ELISA
November 6, 2017 Please read this entire document very carefully. The information is presented in bullet point format to hopefully make complicated information a bit easier to understand. Background: A consumer tested a carton of Quaker Oats labeled gluten-free with the Nima Sensor consumer-testing device. Two samples—one cooked and one raw were tested. Both results were “gluten found”. The consumer sent all remaining product in the original container to Gluten Free Watchdog. Gluten Free Watchdog sent the product to an independent...

Nima Update: Limit of Detection
Post date: July 12, 2017 The following email was sent to subscribers to Gluten Free Watchdog this morning (July 12, 2017): Dear Gluten Free Watchdog community, This email is primarily for those of you who test products using Nima or are interested in this device.

Consumers & Manufacturers: What you must know about gluten test results using the Nima Sensor
In Honor of Celiac Disease Awareness Month, Gluten Free Watchdog is writing a series of articles (the goal is one per day during the month of May) related to the gluten-free diet–currently the ONLY treatment for celiac disease. Post (#30)… At Gluten Free Watchdog we have been testing a wide variety of products with the Nima Sensor. It is very difficult to put results into the proper context due to the lack of a published validation report on this device. Four emerging themes from...

Gluten Free Watchdog Position Statement on Consumer Use of the Nima Sensor to Test Food for Gluten
Bottom line: At Gluten Free Watchdog we have been testing a wide variety of products with the Nima Sensor. It is very difficult to put the results of testing completed to date into proper context due to the lack of a published validation report on this device. One goal of our testing is to provide recommendations for consumer use of the Nima Sensor. This is proving to be impossible at this time. In the opinion of Gluten Free Watchdog the Nima...

What’s to blame for possible false positive “low gluten” test results using the Nima?
Bottom line: Gluten Free Watchdog has personally tested many products using the Nima Sensor. One of the issues slowly emerging is what appear to be false positives (e.g., defined by Gluten Free Watchdog as products testing “low gluten” when tested with the Nima but less than 1 ppm when tested with the R5 ELISA) when testing certain types of samples. The gluten-free foods (and products free of gluten-containing ingredients) testing “low gluten” using the Nima have similar ingredients and consistencies. Note:...

R5 ELISA Test Results for Gluten-Containing Products Testing “Low Gluten” & “High Gluten” Using the Nima Sensor
Bottom Line: Based on testing done to date by Gluten Free Watchdog, products testing “low gluten” using Nima tested from below the limit of detection of 1 ppm gluten up to 18,963 ppm gluten using the R5 ELISA. Barley flour also tested low gluten. Based on these results it is difficult to assess the meaning or understand the usefulness of a “low gluten” Nima reading. Why did we test gluten-containing products: We tested a variety of gluten-containing products out of curiosity...
