A new pocketable device aims to take laboratory-grade food allergy testing out of, well, the lab. The battery-powered Allergen Alert — announced this week at CES — analyzes a small food sample and delivers the results in about two minutes, flagging traces of the major allergens at parts-per-million sensitivity right on the device as well as in a companion app.
About the size of a compact hardcover book standing on end, it pairs with single-use testing pouches sold by subscription. The company markets it as a quick, consumer-friendly check for cross-contamination in restaurants, school cafeterias and at home — no need to send samples to the lab.

How the Tabletop Allergy Test Works, From Sample to Result
Some common dishes are inserted into a sealed pouch with a pea-sized amount of food and put in the contraption, and then users press one button and wait. The throwaway pouch acts as a self-contained test chamber, preventing mess and chances of cross-contamination with other tests. The results display right on the device and sync to the app for record-keeping.
And the new method resembles concepts employed in food safety labs, where screens look for particular proteins present, often at imperceptibly low parts per million (ppm) concentrations. A practical equivalency is 1 ppm = one milligram of allergen per kilogram of food. The company has said its system reports results in about two minutes, significantly faster than many lateral-flow home tests — 10 to 20 minutes is a common time.
What It Screens For and How Sensitive It Is
Allergen Alert references the nine “Big 9” allergens known to the US market (milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat and soy) as well as sesame but doesn’t reference lupin. That final bit is particularly useful to those with celiac disease or a gluten sensitivity, as gluten covers wheat, barley and rye.
Initial specs are ambitious: the company claims sensitivity as low as 5 ppm for milk and 4 ppm for gluten. Context is that the FDA’s gluten-free labeling threshold is under 20 ppm and Codex Alimentarius uses the same — the point being, a detection level of 4 ppm means a cautious screen relative to current labeling requirements.
Why It Matters for Diners and Families Managing Allergies
There are as many as 32 million Americans with food allergies, FARE reports, and a reaction sends someone to the emergency room every three minutes. Sesame was also just recently added to the required US list for food allergen labeling as per the FASTER Act, which highlights how quickly potential risks can still evolve for consumers.
Cross-contact is still the wild card outside of the home. Even the most diligent of kitchens may have allergens travel through cross-contamination, whether via shared fryers, utensils or prep surfaces. A speedy, portable test won’t take the place of a conversation with the chef — or an epinephrine auto-injector — but it might offer another layer of reassurance before that first bite.
Costs and Practical Limits of a Portable Allergen Tester
The device is expected to be priced around $200, with six single-use pouches running on a monthly plan for $25 — or about $4 per test. That cap might feel tight for the frequent diner or the parent screening multiple dishes at a buffet or birthday party. For some households, the sweet spot could be in spot-checking ambiguous dishes, traveling or finding new venues.
Like all rapid tests, sampling strategy counts. Allergens can lurk in “hot spots,” particularly with foods that are mixed or fried. And reaction thresholds vary widely, according to experts at the American Academy of Allergy, Asthma & Immunology; a conservative sampling approach — testing from different parts of a dish where convenient — can minimize false reassurance.
How It Compares to What’s Already on the Market
Commercial allergen tests for professional kitchens and manufacturers are available, but they usually involve benchtop readers, more training and longer run times. There have also been consumer gadgets for single targets such as gluten or peanuts. Allergen Alert’s pitch is breadth and speed: multiprong detection of “the Big 9” plus gluten in minutes, with one workflow and app.
The company has billed it as “lab-grade,” which translates to ppm sensitivity and protein specificity. Independent validation will be key. (Industry certifications like AOAC performance testing or third-party proof-of-concept studies at food science labs might give consumers and restaurants confidence that real-world matrices — oily sauces, heat-treated batters, complex spices — don’t trip up the assay.)
The Bottom Line and What to Watch For Before Buying
For people with allergies, a two-minute check could be life-changing — especially when eating out or considering risk for kids. The sensitivity figures track — if not surpass — typical regulatory standards, and it’s battery-powered to be travel-friendly.
Before you declare a victory, keep questions alive about strong external accuracy data, cross-reactivity and transparent app features that log results and ingredients. Guidance from the C.D.C. and allergist groups still stands: always check ingredients, inquire about kitchen practices and carry emergency medication for a food allergy. (It isn’t going to replace those other steps, if Allergen Alert is as effective as promised — but it could substantially reduce uncertainty at the table in a good way.)
