    Celiac Disease Future: A Device that Detects Gluten in Food?

    Reviewed and edited by a celiac disease expert.

    Celiac.com 10/18/2012 - Currently, there is no convenient way for people with celiac disease to test food for gluten content. In an effort to change that, University researchers in Spain are using Sunrise™ absorbance readers by Tecan, together with Magellan™ V4.0 software to create an accurate, easy to use sensor that can test for gluten in food.

    Photo: CC--chrisinplymouthMaria Isabel Pividori from the Sensors and Biosensors Group at the Universitat Autònoma de Barcelona confirmed the development of the "electrochemical magneto immunosensor for the sensitive detection of gliadin – and small gliadin fragments – in natural or pretreated foods.” Gliadin is the main protein trigger for celiac disease.

    Celiac.com Sponsor (A12):
    The sensor is an important step toward addressing "increasing demand for rapid, simple and low cost techniques for accurate food analysis in decentralized analytical situations," said Pividori.

    The research team measured the performance of the electrochemical immuno-sensor by comparing it with a new magneto-ELISA, using optical detection performed on the Sunrise plate reader.

    The team conducted ELISAs in 96-well microplates, using a magnetic separation plate to isolate the supernatant before measuring the absorbance in the Sunrise reader.

    This enabled the team to conduct immunoassays in a number of various formats for multiple applications – such as evaluating protein coupling to magnetic beads and nanoparticles – as well as allowing assessment of different transducer materials for bio-sensing purposes.

    Because it offers "a quick and easy way to optimize reagents and assay parameters," Pividori calls the Sunrise "ideal for research applications."

    So just how far off is a commercially viable device that will allow people with celiac disease to test gluten levels in their food? Only time will tell, but stay tuned for more developments as researchers try to deliver such a device.

    Meantime, let us know what you think. Would you like a device that could easily and accurately test food for gluten? Would such a device make your gluten-free life better or easier? Comment below to let us know your thoughts.

    Full details of this study can be found in: Laube T et al. Biosens Bioelectron, 2011, 27, 46-52.

    Yes, Yes, it would make my life much easier. I would use it every time I had anything to eat outside of my home.

    This device would simplify my life significantly! I would happily purchase one for myself, my adult son and daughter.

    I would certainly buy one. mainly for when eating out. I often feel stressed when eating out so this would be wonderful!!

    This would be a great breakthrough for those of us who are new to celiac disease. I would buy one and use it all the time.

    I would love to have one to prove to my husband how important cross contamination is. He is the cook of the house and insists that he cooked a gluten-free meal. But unless I prepare my on meals I usually get sick. It hurts his feelings when I don't want to eat his meals.

    Count my vote for it!! I would love it for all the reasons mentioned as well as to check my own cooking for cross-contamination from my kitchen.

    I have been saying for a while that I would pay good money for something like this - it would be worth it just to be sure of what I'm eating and to be able to try things that I regularly wouldn't take the risk with. The only problem I have is if a crumb from cross-contamination is enough to upset my body, then I would need to be able to test the entire amount of food, not just stick it in one place and assume that there's no gluten throughout.

    I would like to know how sensitive this test is. If it can test below 20 ppm to very low levels of gluten I would be happy. My son gets sick from products that contain 5 ppm gluten...

    I would LOVE to have a sensor and have spoken to other coeliacs who all agree. I hope it will be available VERY soon. I can feel a sense of relief already that I will be able to eat safely, especially when I am away from my home.

    Celiac.com 05/27/2008 - People with celiac disease know all too well that the only effective treatment at present is faithfully following a gluten-free diet. There’s been a lot of talk about various therapies and enzyme treatments that would allow people with celiac disease to return to a normal diet. Talk to anyone who suffers from celiac disease and they’ll likely have a personal horror story about a time when they had an unhappy episode of cross-contamination.
    So, the idea of a drug that would prevent such symptoms is appealing, and the goal, desirable. The chief cause of recurring symptoms in celiac disease is accidental gluten exposure, usually through cross-contamination. Cross-contamination doesn’t always mean food. Gluten is a common ingredient in many medicines and vitamins, and ...

    Celiac.com 11/15/2008 - Managing celiac disease can be challenging in the best of circumstances, so imagine the frustration of experiencing on-going gastro-intestinal symptoms even while following a gluten free diet. Such frustration is increasingly common among people with celiac disease.
    With increasing frequency, doctors worldwide are finding persistent villous atrophy in celiac patients who are following a gluten-free diet. Results of a study published recently in the Scandinavian Journal of Gastroenterology indicate that persistent intestinal villous atrophy in celiac disease patients on a gluten-free diet is associated with gastrointestinal symptoms considered 'atypical' for celiac disease and which are different from those present at the original celiac disease diagnosis. ...

    For the first time, researchers at the University of Chicago Celiac Disease Center will use mouse model research to explore root causes of celiac disease, test new therapies, and explore new targets for treatment.
    Celiac disease is the most common genetic autoimmune disease in the world. Celiac disease affects approximately three million Americans, but only three out of every one hundred people with celiac disease have been diagnosed.
    At least ninety-seven percent of people with celiac disease undiagnosed. Untreated celiac disease can lead to osteoporosis, infertility, neurological conditions, and cancer. Moreover, people with celiac disease have a substantially higher risk of developing other autoimmune diseases, especially Type-1 diabetes.

    Celiac.com 06/20/2014 - Celiac disease is a T cell–mediated disease triggered by the protein in wheat gluten. More than 9 out of 10 of people with celiac disease carry human leukocyte antigen (HLA)-DQ2 locus.
    A team of researchers recently set out to determine if T-cell receptor recognition of HLA-DQ2–gliadin complexes was connected with celiac disease.
    The researchers included Jan Petersen, Veronica Montserrat, Jorge R Mujico, Khai Lee Loh, Dennis X Beringer, Menno van Lummel, Allan Thompson, M Luisa Mearin, Joachim Schweizer, Yvonne Kooy-Winkelaar, Jeroen van Bergen, Jan W Drijfhout, Wan-Ting Kan, Nicole L La Gruta, Robert P Anderson, Hugh H Reid, Frits Koning, and Jamie Ross.
    They are variously affiliated with the Department of Biochemistry and Molecular Biology at ...

      Celiac Maybe a Possibility?

      It seems you have proven that you cannot eat gluten. You've done what your doctors have not been able to do in 40 years. That's your low vitamin D, a common symptom with Celiac Disease. Zinc is also a common defiency. Its an antiviral. that's why zinc gluconate lozenges work against airborne viruses. Vitamin D and the Immune System+ ...

      Weird Symptoms

      My mother also has celiac disease, and one of her symptoms for many years before her diagnosis was TMJ. I believe it took her many years on a gluten-free diet before this issue went away.

      Weird Symptoms

      Ear pain and ringing your entire life may or may not be TMJ related but could be something else. A good TMJ exam would be helpful to rule that out as a potential cause from a dentist who treats that. I have teens as well as adults of all ages who suffer from TMJ issues so it’s not a certain age when it shows up.

      Weird Symptoms

      Not sure if related to coeliac disease but my ear ringing has stepped up a notch since diagnosis. Even since a child silence really hurts my ears - there is always a really loud noise if there is no other noise in a quiet room - but my brain has learned to filter it out. Since diagnosis in my forties I also get a metallic ringing in my ears, sometimes...
