Some of the test vials leaked inside the pack so when you open it you can’t use it.

It works well and gives ease when eating out

Amelia

Before we had this product, we avoided many restaurants because the risk felt too high. Our child often felt disappointed when we said no to eating out. Now we occasionally test certain foods when we’re unsure. Being able to verify food safety helps us feel more comfortable letting our child enjoy dining experiences that used to feel impossible.

When traveling with a celiac child, this gives us extra confidence.

Before we found this product, we avoided many restaurants and social events because we were afraid of accidental gluten exposure. Our child often felt left out because of that. Now we feel more comfortable letting them try new foods in certain situations. Having a way to check food if we’re unsure makes a big difference for our family.

Dining out is less stressful now.

How's LEO Different

Traditional lab tests take hours for results, leaving you in limbo. Some portable sensors offered faster results, but were often expensive and detected gluten down to 20 ppm which triggered reactions in sensitive individuals. LEO bridges this gap.

10 PPM

Our innovative technology utilizes a specialized monoclonal antibody that detects gluten at 10ppm or less, giving you the confidence you deserve.

Rapid Result

LEO delivers clear results in 3 minutes, empowering you to make informed decisions on the spot. No more waiting in limbo or relying on potentially inaccurate labels.

Precision

Existing portable sensors often fall short on accuracy, especially for trace amounts of gluten. LEO utilizes a sophisticated lateral flow assay with high-affinity antibodies to catch even the tiniest amounts of gluten that could trigger reactions.

Portable

LEO's compact size allows for on-the-go testing, so you can enjoy dining out or exploring new foods with peace of mind.

Easy to Use

No complicated steps or confusing instructions. Swab your food, dip in the solution, add a few drops on sensor, and let LEO do the work.

100% Surface Safety

Most biosensors are limited to testing food only. LEO enables you to test surfaces like grills and cookie sheets. So you can feel safe and protected when visiting friends & family.
