CES 2026: This portable device will test meals for allergens in minutes

For people with food sensitivities, dining out can be a hassle at best and dangerous at worst. But soon, a new portable gadget the size of a mass-market paperback could allow you to quickly test meals for allergens and gluten at the table.

At the CES 2026 Unveiled press event on Sunday, French startup Allergen Alert debuted its mini lab, a battery-operated device that "automates and miniaturizes every step of a professional analytical test," according to the company. The version of the product I saw on the showroom floor wasn't market-ready, but company reps say its final form will use a small portion of food that's scooped into a single-use pouch to test for gluten and popular allergens, providing near-instant results.

The mini lab will allow users with allergies or celiac disease to self-screen their meals instead of just trusting restaurants to keep triggering ingredients off their plates, lessening the risk of a potentially deadly accidental exposure, according to the company.

Allergen Alert CEO and founder Bénédicte Astier says she came up with the idea for the mini lab as her daughter recovered from anaphylaxis triggered by a dairy allergy. "I experienced what too many families know all too well: the fear that life can change because of a single meal," she said in a press statement. "I realized we needed an extra safety belt; a way to test food anywhere, at any moment. Something concrete, reliable, and immediate that gives back control to people with allergies and those who care for them."

Astier made the mini lab a reality as part of an intrapreneurial program at biological diagnostics company bioMérieux, her former employer.

Allergen Alert finished a €3.6 million ($4.23 million USD) fundraising round in October and plans to launch the mini lab in the second half of 2026. The device itself will cost around $200 and its testing pouches will be supplied in packs of five to seven as part of a monthly subscription. Each pouch can only test for one allergen at a time, but a company rep told me that it might eventually support multiple allergens per test if it becomes a frequent user request.

According to that same rep, the mini lab I saw on the CES Unveiled showroom floor was a nearly finalized prototype. Its technology is ready to go, but the exterior design is still getting polished.

Anyone familiar with the Theranos saga has the right to be skeptical of a device that promises fast lab-grade results in a non-lab setting, but Allergen Alert's team assured me that it does indeed work. We'll find out when it launches later this year.
