Thanks Karen.  I like the videos by Tricia Thompson that are linked in the comments on the article.  She explains some issues about the testing process and correctly preparing samples for testing.  Very informative.  If they come out with a sensor that detects wheat, rye, barley, oats, peppers, tomatoes, potatoes, eggplant, soy, celery, and dairy I might even consider trying it.

I am a GlutenFreeWatchdog member.  I also support Consumer Reports.  I like the idea of someone adocating for those with celiac disease or gluten intolerances.  

For now, I will stick to my primary gluten tester -- my brain.  Reading labels, calling manufacturers, eating at restaurants recommended by celiacs,  and posting on this forum has worked for me.

Interesting on this, I sent in the Mantoba harvest and the Upton to the lab. I have since apologized for snapping at the uptons products and started questioning the Nima more often.   On a side note the sample from the Mantoba Harvest Hemp tested low and came back 6ppm.....Should I be concerned as a celiac on this? Or should I consume the product and hope I do not hit a hot spot.....sorta have a $60+ bulk order of the stuff .    Got it on a whim thinking it might be safe, issue is I consume the stuff like 1/4cup at a time and if it got 6ppm on a small sample......well you see where I am going here in reference to the amount of potential gluten I could consume.     Just seems like a waste to trash it.......so far I have been lucky using it. Only noticed a slight twitching, numbness, and looser stools. Nothing major.....like puking, cramps, or oddly enough even the brain fog is not registering where I have noticed it.

"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."

"...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.   ...."

.." 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 Sensor was released into the marketplace prematurely. Given the current state of development of this sensor, Gluten Free Watchdog cannot support its use by the gluten-free community at this time...."
