Nima Manual: How to Use Nima

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

  • 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.

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. If Contact Nima Support displays after a Capsule Error, you may not pushing the capsule all the way down. Try again, fully pushing the capsule all the way in until it clicks. If the issues persists, contact support ( There might be a problem with the camera.
