Just tried out the Nima on some non gluten-free certified hemp protein I got on a good deal. Came back gluten positive, well figured that was to good to be true. Saved me finding  out the hard way.

Yeah...sorta had a part in that, jeez feel like a ass. Anyway at least it is not giving false negatives. Rather have it go off on trace amounts then miss a contamination. Though it has caused some unnecessary whistle blowing, really am questioning it a bit more now.

I think the NIMA would be best suited for use in restaurants and not so much for pre-packaged foods.  It is also very important to read all directions before using as there are limitations, which are clearly stated, to it's use. 

I never worry about pre-packaged foods because I choose my processed foods wisely. If a company is labeling their food as gluten free, then they must test so they are already doing the testing for you.  The only time I was ever sick from a processed food was in the very beginning and it was a brand that became known for some issues with people getting sick.  After 12 years, knowing what is safe becomes second nature. 

Restaurant food, when traveling, is my only concern.  Again, I choose my places wisely from folks who have vetted these places and reported them on reputable Celiac websites.  I also take into consideration how I am treated when there and answers to questions asked on food prep. You cannot rely on a single source for safety when deciding on whether food is safe to eat.

The NIMA team clearly states that their tester will not work on soy sauce or fermented foods so testing Asian foods will not be reliable.  But with most other types of cuisine, as long as they don't contain some of the ingredients listed as a problem, testing should be straight forward.  No one should have the expectation it will test as well as an ELISA lab test but used as a tool in the total decision making process, it can be a great resource.  I am keeping track of every restaurant meal I test when traveling and whether or not I think it may have been wrong, depending on how I feel the next day. I always know if I have been glutened, which is not very scientific but if the NIMA says safe and I get sick, that will give me some useful information.  I think this device is pretty damn good for a first try and I really think down the road, we will have VERY accurate testing means available to help us dine out more easily.  I think that far more likely to happen than anyone coming up with the cure that they keep touting about. Funny enough...I am not remotely interested in a cure but would like accurate testing for dining out when traveling. That's the only time I worry about a hit.

People miss- using it, testing foods it can't test, cross- contaminating the sample themself, etc.  these are all reasons I don't go by what some random person says tested positive.  Seen it with other testing methods.

Yeah I been testing it more, always use a disposable plastic sample fork for loading it. Seems it is very sensitive, will give false positives on certain products, will also clog and error out if there is not enough liquid present in the sample. Has issues with foods high in tannin, acids, bright in colors, or containing vinegar. On the bright side, at least it does not give false negatives, so better safe then sorry with it, just do not use it to go throwing flags around and calling people out. I made this mistake at first trusting it like I did EZ strips. It is less expensive for a reason I guess, still a nice convenient gadget, hoping for a updated version with better accuracy and reliability.

I hope, if you posted in various places that a product has gluten,  but it does not, that you have gone back and corrected that.  Making claims like that can cause you legal issues.

As with the gluten free diet, there is a learning curve to using one of these and you have to read all instructions on its use.

It was  a bit more of a questioning statement I had where I  mentioned sending it off to get official test done on the forums. I have posted a update on here where I did so. I thankfully held off til the test came back before emailing the company about food poisoning. I only inquired to their production line, where they mentioned they did not certify anything gluten free, as they did process wheat in the facility. -_- I feel like a  ass for assuming that a device like that would be 100% accurate.

I would like to point out one thing to everyone on this board: If you purchase the NIMA, the app is NOT required to use it. If you download the app, please know that you are turning over detailed information about your self and your eating habits not only to NIMA  but also to Google and/or Apple.

While NIMA claims to currently anonymize the information, nothing prevents it from changing its position in the future.

Nothing prevents either Google or Apple from using the information as it pleases.

Many people may scoff at my position, but no one can say whether insurance companies or even employers may obtain the information in the future and how they may use 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.

To me, any gluten is unsafe. I use the device to tell me something is bad. A smiley face does not mean to me that something is good. Just a tool in the box.

"t 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."

      Welcome to the forum, @Judy M! Yes, he definitely needs to continue eating gluten until the day of the endoscopy. Not sure why the GI doc advised otherwise but it was a bum steer.  Celiac disease has a genetic component but also an "epigenetic" component. Let me explain. There are two main genes that have been identified as providing the "potential" to develop "active" celiac disease. We know them as HLA-DQ 2.5 (aka, HLA-DQ 2) and HLA-DQ8. Without one or both of these genes it is highly unlikely that a person will develop celiac disease at some point in their life. About 40% of the general population carry one or both of these two genes but only about 1% of the population develops active celiac disease. Thus, possessing the genetic potential for celiac disease is far less than deterministic. Most who have the potential never develop the disease. In order for the potential to develop celiac disease to turn into active celiac disease, some triggering stress event or events must "turn on" the latent genes. This triggering stress event can be a viral infection, some other medical event, or even prolonged psychological/emotional trauma. This part of the equation is difficult to quantify but this is the epigenetic dimension of the disease. Epigenetics has to do with the influence that environmental factors and things not coded into the DNA itself have to do in "turning on" susceptible genes. And this is why celiac disease can develop at any stage of life. Celiac disease is an autoimmune condition (not a food allergy) that causes inflammation in the lining of the small bowel. The ingestion of gluten causes the body to attack the cells of this lining which, over time, damages and destroys them, impairing the body's ability to absorb nutrients since this is the part of the intestinal track responsible for nutrient absorption and also causing numerous other food sensitivities such as dairy/lactose intolerance. There is another gluten-related disorder known as NCGS (Non Celiac Gluten Sensitivity or just, "gluten sensitivity") that is not autoimmune in nature and which does not damage the small bowel lining. However, NCGS shares many of the same symptoms with celiac disease such as gas, bloating, and diarrhea. It is also much more common than celiac disease. There is no test for NCGS so, because they share common symptoms, celiac disease must first be ruled out through formal testing for celiac disease. This is where your husband is right now. It should also be said that some experts believe NCGS can transition into celiac disease. I hope this helps.

      My husband has had lactose intolerance for his entire life (he's 68 yo).  So, he's used to gastro issues. But for the past year he's been experiencing bouts of diarrhea that last for hours.  He finally went to his gastroenterologist ... several blood tests ruled out other maladies, but his celiac results are suspect.  He is scheduled for an endoscopy and colonoscopy in 2 weeks.  He was told to eat "gluten free" until the tests!!!  I, and he know nothing about this "diet" much less how to navigate his in daily life!! The more I read, the more my head is spinning.  So I guess I have 2 questions.  First, I read on this website that prior to testing, eat gluten so as not to compromise the testing!  Is that true? His primary care doctor told him to eat gluten free prior to testing!  I'm so confused.  Second, I read that celiac disease is genetic or caused by other ways such as surgery.  No family history but Gall bladder removal 7 years ago, maybe?  But how in God's name does something like this crop up and now is so awful he can't go a day without worrying.  He still works in Manhattan and considers himself lucky if he gets there without incident!  Advice from those who know would be appreciated!!!!!!!!!!!!

      You've done an excellent job of meticulously tracking the rash's unpredictable behavior, from its symmetrical spread and stubborn scabbing to the potential triggers you've identified, like the asthma medication and dietary changes. It's particularly telling that the rash seems to flare with wheat consumption, even though your initial blood test was negative—as you've noted, being off wheat before a test can sometimes lead to a false negative, and your description of the other symptoms—joint pain, brain fog, stomach issues—is very compelling. The symmetry of the rash is a crucial detail that often points toward an internal cause, such as an autoimmune response or a systemic reaction, rather than just an external irritant like a plant or mites. I hope your doctor tomorrow takes the time to listen carefully to all of this evidence you've gathered and works with you to find some real answers and effective relief. Don't be discouraged if the rash fluctuates; your detailed history is the most valuable tool you have for getting an accurate diagnosis.

      In this case the beer is excellent, but for those who are super sensitive it is likely better to go the full gluten-free beer route. Lakefront Brewery (another sponsor!) has good gluten-free beer made without any gluten ingredients.

      Welcome to the forum, @catsrlife! Celiac disease can be diagnosed without committing to a full-blown "gluten challenge" if you get a skin biopsy done during an active outbreak of dermatitis herpetiformis, assuming that is what is causing the rash. There is no other known cause for dermatitis herpetiformis so it is definitive for celiac disease. You would need to find a dermatologist who is familiar with doing the biopsy correctly, however. The samples need to be taken next to the pustules, not on them . . . a mistake many dermatologists make when biopsying for dermatitis herpetiformis.
