Nima test results are only representative of the sample tested and is not a guarantee of the entire dish. Use of this product should not replace education, medical advice, compliance with food labeling and adherence to avoidance strategies. Failure to use this product in accordance with the instructions could result in serious injury or death. Read full directions in this manual before use.
Nima is another tool to help you understand if there is gluten in your food. Nima has been developed and validated to test food items only (both solids & liquids). Nima has not been validated on medication, cosmetics or non food items. Nima only tests the sample that is in the device and therefore, Nima does not guarantee that your entire item or dish is gluten-free. Please use your best judgement when choosing what to consume.
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 protein present in the sample. 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 the Nima Gluten Sensor can and cannot test (see below) and how to sample (see below) is critical for accurate and reliable results.
Nima is 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!
Nima’s chemistry is antibody based. The Nima Research & Development (R&D) team developed a pair of antibodies specifically for the detection of gluten. There are existing gluten antibodies on the market, but none of them were sufficient to meet the speed, sensitivity and specificity requirements that we needed for Nima. The Nima 13F6 and 14G11 antibodies bind to a gluten protein called the 33-mer fragment, which is known as the ‘toxic’ portion of the protein that causes an auto-immune response.
Do Not Test
Based on internal lab testing, the Nima Gluten Sensor may incorrectly show a ‘Smile’ message when testing the following items:
- Fermented Foods such as beer
- Hydrolyzed Foods such as soy sauce
- Pure Xanthan or Guar Gum
The above list may change. Here is a full list of foods Nima’s research and development (R&D) team has tested and any special testing recommendations and ongoing updates to the do not test list.
Since Nima cannot guarantee your entire plate is free from a particular allergen, it’s important to try and get a representative sample to test. In order to try and get a representative sample, it is recommended to test multiple points from across your plate – being careful not to overfill the capsule.
Testing multiple points in a single test capsule or using multiple capsules if needed will help in identifying contamination.
If an item is ordered with a gluten substitute, it is recommended to test the item that was replaced or the most likely point where contact may have occurred (grill marks, cut marks, etc.)
Prepare a sample
Most liquid and solid food samples can be put in a capsule as-is. However, to ensure an accurate test, some manipulation might be helpful for special types of food.
Thick / Dense Foods
Thick samples such as nut butters and fudge should be tested with 1:1 dilution of water to prevent clogging and slow flow. If thick samples are not manipulated, they may yield a false negative.
Dry / Powdery Foods
Spices and flours should be tested at a lower weight (less than ⅛ teaspoon) and with 1:1 dilution with water.
Brightly Colored Foods
Bright foods can interfere with the sensor’s ability to read the result. These foods should also be mixed with water to dilute the coloring.
In addition to sample manipulation, ensure your sample is the appropriate size. That size is approximately .3g or approximately the size of a pea. Light or fluffy foods (such as puffed cereal) samples should be sizeable enough to help ensure the weight is appropriate for testing.

Interpret the results
No gluten detected in the sample tested. Nima is optimized to detect 20 ppm or above of gluten with high sensitivity. In some food matrices, Nima will also detect lower levels of gluten.
Gluten detected in the sample tested.
Things to consider after receiving a Gluten Found result:
1. Is your device firmware up to date? The newest firmware will ensure your device is functioning at optimal levels.
2. Nima will give a Gluten Found if any detectable gluten is found. The device is optimized for 20 ppm and above but has detected levels below in lab testing of some foods. For packaged food labeled gluten free, the level of gluten could be present at a level that is technically acceptable for the labeling standard being used.
3. Consider everything you know about the item being tested:
A.) Are you at a restaurant? Have you eaten there before? Do you trust the staff?
B.) Is the packaged food labeled in any way? Gluten-free? Certified gluten-free? What’s the brand? What does their website say about their quality control measures? Have you eaten the item before?
C.) Here are some additional conversations starters to use at restaurants
and with packaged food companies

No Test Result
Nima was unable to give you a conclusive result. Nima may have had difficulty providing a result because of the sample size, food type, chemistry or a mechanical issue. Click here to see tips on how to ensure a successful test.
The Nima sensor has had an issue with the capsule being tested. Confirm that 1.) The capsule was not used for a previous test 2.) The expiration date has not passed 3.) There is nothing inside the Nima sensor that may be obstructing the inside of the 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.
Update Your Firmware
Nima is designed to run most optimally with the latest over-the-air updates, which can be accessed through a firmware update through the Nima mobile app on Android and iOS. To update, download the Nima app, create an account and login. When prompted, pair your device to the app. Navigate to the map page. If a firmware update is available, a banner will prompt you to update.</>
Best Practices for Use
- Leave capsules wrapped until you are ready to use them.
- Store capsules in a temperate environment. Ongoing exposure to extreme heat and cold will damage the integrity of the test. Capsules should not be exposed to heat above 90 degrees Fahrenheit (32 degrees Celsius) or below 32 degrees Fahrenheit (Zero degrees Celsius) for prolonged periods of time. Do not regularly store capsules in a hot car or freezer.
- 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. Reusing a capsule will result in an error.
- For best results (and avoiding test failures) you may need to crush, chop, or shred your food samples.
- Do not ingest test liquid or consume food sample from capsule 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.

Running a Test
Nima is running a test. This icon indicates something is happening. Might be accompanied by a noise – this means Nima is processing your food. There is a progress bar to indicate how far into the test you are.
Place Nima upright on a flat surface when running a test. Too much movement of Nima during testing may cause a failure.
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 purple ring and the cap should be flush with the body. Confirm the capsule is fully inserted into Nima. You should feel it click when it’s properly inserted.
This result will display on Nima when the capsule top does not appear to be fully closed and flush. If you see this message, remove the capsule and try to further tighten the cap. The last few millimeters can be difficult – especially if the capsule has been overfilled or if the food is especially dense. The purple 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.
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.
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.
If Nima’s battery runs out during a test, you will be unable to remove the capsule until Nima is once again charged. Once charged, you will need to push the button to complete the test prior to being able to remove the capsule.
Sensor and capsules should be stored in a temperate environment. Heat above 90 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.
