How does Nima work?

With Nima, we have taken a complex laboratory style test and shrunk it into a simple, portable device. Closing the capsule prepares the food sample for mixing and testing. Our antibody chemistry then detects if there is gluten. Finally, our sensor reads the result.All of this allows you to feel more confident in your decision-making about what to eat.Nima should always be used in conjunction with clear advocacy for gluten free options and your better judgement. Your understanding of what Nima will detect or not and how to sample is critical to gaining accurate and reliable test results. It’s intended to give you an additional data point and level of comfort when eating but is not a guarantee as we can only provide a result for the sample being tested. It is still your responsibility to do everything you can to let waitstaff know your needs, to ask friends to prepare gluten-free meals,to purchase items that are clearly gluten-free, and to advocate for yourself. Whether or not you wish to eat something will be up to you. We encourage everyone to download the Nima app for iOS or Android and pair your Nima so you can access your test history, receive firmware updates for improved device performance and share your results with the growing community!

How to Run a Test

Best practices for use

  • Thoroughly read sampling instructions and information about interpreting test results.
  • Leave capsules wrapped until ready to use.
  • Store capsules in a temperate environment. Extreme heat and cold will damage the integrity of the test. Do not store capsules in a hot car.
  • Wash hands before testing to help avoid cross contamination.
  • Wipe outside of capsule clean of excess food and liquid before placing in Nima.
  • Use a fresh capsule for every test.
  • Prevent testing errors by crushing, chopping and shredding your food samples.
  • Do not ingest test liquid or consume food sample after testing.
  • Do not re-open the capsule after use. Throw capsule away. Not currently recyclable.
  • Wash hands with soap if you come in contact with testing fluid.

Stand Up

Place Nima upright on a flat surface when running a test. Too much movement of Nima during testing may cause a failure.
Nima Manual: Nima doesn't see a capsule. Insert one to start a test.

Insert Capsule

Nima does not recognize or detect a capsule to test. Confirm the capsule top is fully closed. If it’s not, the capsule will not click into place. A fully closed capsule shows no green ring and the cap should be flush with the body. Confirm the capsule is fully inserted into Nima. You should feel it catch when it’s properly inserted.

Capsule Error

Nima has an issue with the capsule being tested. Confirm 1.) The capsule was not used for a previous test 2.) The expiration date is in the future 3.) There is nothing obstructing Nima’s front window – use a clean cloth to wipe the inside of Nima as well as the outside of the capsule. If all conditions are met, re-run capsule. If an error still occurs, run a new test with a new capsule.

Tighten Capsule

“Tighten capsule” will display on Nima when the capsule top does not appear to be fully closed. If you see this message, remove the capsule and try to further tighten the cap. The green ring should not be visible and the top of the capsule should be flush with the body. Once the cap is closed and aligned, re-insert the capsule and try to run the test again.
Nima Manual: Battery with slash means low battery and Nima needs to be charged.

Low Battery

Battery needs to be charged. See the “Battery” section under “Maintenance” for more information on battery life.



Both the inside and outside of the sensor can be cleaned with a damp cloth. At no time should Nima be rinsed or submerged under or in water. Don’t get moisture in any openings or use aerosol sprays, solvents, or abrasives.

Battery life

Nima arrives charged. On average, battery charge lasts around 40 tests. Battery will last around 3 months if no tests are being run and Nima is off. Device will turn off automatically if not being used. From a completely dead battery, Nima will take 1 hour and 15 minutes to fully charge.The Nima is charged via the USB micro connector. You can plug the Nima to any USB 1.0 or 2.0 micro charger or directly into a USB port on your computer. The Nima is compliant to USB 1.0 and 2.0 current limitations and will not draw more than 300mA of current at its maximum charge rate.

Storage temperature

Sensor and capsules should be stored in a temperate environment. Heat above 110 degrees Fahrenheit can cause damage. Don’t expose your Nima to extreme heat or cold. To avoid potential issues, do not store in a vehicle during hot or cold temperatures.


Handle Nima with care. Nima contains sensitive electronic components, including a battery, and can be damaged or cause injury if dropped, burned, bent, crushed, or if it comes in contact with liquid. Do not use a damaged Nima.
