The Emerging Role of Gluten Detection Sensors in Celiac Disease Care, With Jignesh Shah, MD

As the management of celiac disease continues to rely almost entirely on strict dietary avoidance, emerging technologies are beginning to reshape how patients navigate daily life. Portable gluten detection sensors are generating both excitement and skepticism within the celiac community as new devices continue to enter the market.1

In an interview with HCPLive, Jignesh Shah, MD, emphasized that while diagnosis remains the most challenging step in celiac disease management, the long-term burden often shifts to education and lifestyle adaptation. He noted that once confirmed, care transitions toward helping patients and families navigate dietary restrictions, behavioral modifications, and ongoing monitoring. This is where new tools, including portable gluten sensors, may offer meaningful support.

These devices, such as the NIMA sensor, rely on immunoassay-based technology similar to rapid antigen tests. A small sample of food is inserted into a disposable cartridge, which is then analyzed for gluten content. Results are displayed in a simple, user-friendly format, indicating whether the food is safe to consume.

According to Shah, this type of accessibility is key: “Easy interpretation and that kind of technology is what we need for consumers. Sometimes, we have to provide some reassurance. So devices like this are really, really needed as a tool for patients out there.”

In January 2026, Nima announced its next generation of the NIMA™ Gluten Sensor, branding it as the first handheld gluten detection device reengineered for faster, more dependable results. As described in a press release from the Company, it is the only portable solution capable of identifying all major gluten sources, including wheat, barley, and rye, down to 10 ppm with 99% accuracy, as confirmed through independent third-party laboratory testing.2

“Once that diagnosis is done, essentially, what am I going to do as a gastroenterologist? I can just reassure, reassure, reassure, but when you start having devices like that, I can provide some objectivity, I can provide a resource, I can provide a tool,” he said.

However, Shah cautioned that it is still early in the adoption curve and stressed that these sensors should be viewed as adjunctive tools rather than definitive diagnostic instruments.

Clinically, he described particular value in targeted, situational use. For example, patients navigating social settings, such as dining out, may benefit from having an on-the-spot method to assess uncertain foods. He described the case of a college student newly diagnosed with celiac disease who wanted to maintain a normal social life. Rather than restricting her activities, Shah recommended selective use of the device in moments of doubt.

Additionally, these sensors may help address unexplained symptoms or persistently elevated serologic markers despite reported adherence to a gluten-free diet. In such cases, the device could help identify hidden sources of cross-contamination, offering both patients and clinicians greater insight into real-world exposures.

Looking ahead, Shah anticipates that adoption of these technologies will grow, though incorporation into formal guidelines may take time and require robust clinical data. For now, he believes the value lies in their ability to fill a gap in patient support.
