Gluten Free Watchdog calls on Nima Labs, Inc. to release third party testing data to their community and to others interested in using the Nima Sensor.

Nima Labs, Inc. has presented useful third party testing data of their Nima Sensor device at selected conferences, but has requested that conference attendees refrain from more widespread dissemination. We are asking them to release the data privately to their users and to others interested in using the device.

Adrian Rogers Discusses Personal Gluten & Allergen Detection Devices such as Nima

November 23, 2017

Adrian Rogers, Senior Research Scientist at Romer Labs, recently spoke at Food Matters Live in London about consumer food testing devices for gluten and allergens (e.g., Nima Sensor). He generously gave permission for his slides and the audio from the live presentation to be posted on Gluten Free Watchdog. This is an exceedingly important presentation to listen to for everyone interested in learning about these devices.

For the best learning experience, please view the slides and listen to […]

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 […]

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 […]

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 […]

Products testing low gluten using the Nima Sensor test less than 5 ppm using the R5 ELISA: False Positives?

Bottom Line: In some cases packaged food labeled gluten-free (or appearing to be free of gluten containing ingredients) testing “low gluten” using the Nima may test below the lower limit of quantification of 5 parts per million of gluten (and below the limit of detection of 1 ppm) using the fully validated R5 ELISA Mendez Method (Ridascreen Gliadin R7001).

Comparison Testing: Results comparing the Nima to the R5 ELISA included in this summary report are for the same product. In […]
