FAQs About Nima

Nima Sensor

The triangle shaped sensor will fit into the palm of your hand. Your food sample in analyzed and evaluated for gluten.

How long does the test take?

Nima's testing takes approximately 3 minutes to detect gluten in your food. Just enough time to take and post a selfie with your meal!

How long the test takes may depend on how much gluten is present in a sample. If the gluten level is high, the test will take less time. If there are lower levels of gluten, Nima may take a bit longer to identify, making for a slightly longer test time.

Can I test more than restaurant food?

Yes! Nima is great for spot checking ingredients that you use at home. There are many good items available that are not specifically labeled gluten-free by the manufacturer. You can easily test a sample to determine if it safe to include in your gluten-free diet. Some of our favorite things to test in Singapore include spice blends, sauces, and flours made from gluten-free grains. 

What’s Nima's level of detection for gluten?

If Nima detects ANY gluten proteins in the sample, you will receive a "Gluten Found" message.

Nima is not a quantitative test but has been tuned to detect with a high level of accuracy at 20 ppm and above. The United States FDA requires that any product labeled "gluten-free" contain a maximum gluten content of 20 ppm. You can find more information about the FDA's food-labeling requirements and what 20ppm means by clicking here. In some food matrices, Nima will also detect lower levels of gluten.

Your results can vary based on food tested, size of sample, and product usage. Nima is a screen and not an absolute - testing one part of a dish may miss gluten elsewhere on a plate.

At what level below 20 ppm do you detect gluten?

Based on internal testing, Nima has detected gluten at levels as low as 5 ppm. If Nima detects gluten at any level, the "Gluten Found" message will appear on the device.  

Nima Capsules


A small amount of food goes into a new Nima Capsule. Take a few capsules along with you to sample various food items.

Do the capsules expire?

Yes. We guarantee capsule shelf life of 9-12 months from delivery. Each capsule has an expiration date printed on both the box, the foil package and the capsule itself. The expiration dates are used to ensure the live antibody based chemistry is fresh and your test is accurate.

The expiration dates on the capsules are displayed in month-day-year format. Use older capsules first and newer ones last. If a capsule is beyond its expiration date, throw the capsule in the trash.

As we make advancements in the shelf life of the capsules, we will make sure to keep the community posted!

How do I store the disposable test capsules?

Capsules should be stored in a cool, dry place. Capsules can be affected by heat and should not exceed 92 degrees Fahrenheit. Do not store in a hot car or other hot environment. If you are living in a warm climate, you can place the capsules in your refrigerator, but do NOT freeze them.

Throw away immediately after use. Do not store capsules (used or unused) in Nima.

Why do I have to use a fresh capsule every time?

Each capsule is essentially a tiny chemistry lab that fits in the palm of your hand, and contains a small amount of our testing solution, grinding elements, a test strip, and other elements that help Nima find gluten in samples of food. When a test is performed these elements are used-up and need to be replaced for Nima to perform another test.

Nima is extremely sensitive to gluten, so even our chemistry team's best efforts at re-using capsules after cleaning them through traditional methods (soap, water, scrubbing) weren't able to fully remove gluten residue from previous tests in a large enough amount to make the capsule re-usable without errors. By using a fresh capsule every time, you'll know exactly what it is you're testing and cross-contamination between samples (as well as incorrect or inconclusive test results) becomes a non-issue. You can read more information about the reasons behind our decision to use disposable capsules for Nima here.

Can I reuse the disposable capsules if I clean them, or if there's no contaminant in the original sample?

Unfortunately, no. We spent a lot of time on our testing process, and over time we found that the best way to make Nima reliable and easy to use was to make the capsules one-time-use only (even if the test comes back as clear of the contaminant).

The disposable test capsules for Nima are essentially tiny chemistry labs that fit in the palm of your hand. Each contains a little bit of our proprietary testing solution which helps to "re-charge" the chemical component of the Nima sensor for each test and is used-up once a test has been completed.

Nima is also super-sensitive to the proteins it's detecting, and it's essentially impossible to get a capsule clean after is has been contaminated. This means they are not washable. Capsules should be thrown away after use.

There are a lot of reasons why it made the most sense to us to use disposable capsules with Nima, and if you'd like to read more about how we arrived at this decision you can read a blog post from our science team about it here

Nima App


Your Nima Sensor can connect to your phone via bluetooth. All your tests can be saved and logged in their app. You can also see what other people have tested in Singapore!

Does Nima connect to my phone?

Nima works on its own without the use of phones or apps or other extensions, but it can connect to some iOS and Android devices with our proprietary app to add additional features like posting your results or sharing your experience at the restaurant where you're testing your food. Nima's connection to your phone operates via bluetooth; Nima does not physically connect to your devices. 

Does the Nima App show tests in Singapore?

What does Nima test for?

The Nima Gluten Sensor tests samples of food for gluten, a protein found in wheat, barley, and rye.

There are limitations around Nima's ability to detect gluten in all substances. For example, fermentation/hydrolization produces changes in the gluten protein, so Nima won't be able to detect hydrolyzed gluten, or gluten in fermented foods (such as soy-sauce or gluten-removed beers).

Corn, rice, and oats, while glutinous (meaning "like glue in texture") do not contain the same gluten protein found in wheat, barley, and rye that people with Celiac disease or gluten sensitivities react to, so Nima doesn't search for corn, rice, or oats in samples of food. Nima would however search for gluten contamination in those foods.

How much does Nima cost?

Nima Sensor $389

Includes the sensor, a charging cable and a carrying pouch.

Refill Capsules, 6 pack $45

Once you have a Nima sensor, you will need to purchase additional capsules to continue testing. Capsule Refill Packs include 6 one-time-use test capsules and can be purchased as needed through GlutenFreeSG.com. 

How well will Nima detect cross-contamination?

Nima will catch cross-contamination / cross-contact instances where foods may be cooked in the same oil (french fries, for example) or in the same water (such as gluten free pasta being cooked in the same water as wheat-based pasta).

Nima can only test the sample of food placed into a capsule. There may be times when cross-contamination occurs in food handling that Nima will not catch if you sample from a different area on the plate. There are tips and tricks to help Nima account for certain methods of cross-contamination, but even with the extra data Nima can provide, you should always use your best judgment in choosing what to eat and what to avoid. Always have a thorough discussion with your server regarding food allergies or sensitivities.

Can Nima tell me if I’ve been contaminated (if I test my own body)?

Nima is designed to let you know if it finds an ingredient you're trying to avoid in dishes before you eat them.

Nima cannot tell you whether or not you’ve already eaten something you're trying to avoid.

Is Nima for only for celiacs?

Nima is helpful to anyone following a gluten-free diet. 

Nima can definitely be helpful to people with celiac disease. It's not a cure but may help empower you to make more informed decisions and eat with less anxiety.

Different people react differently to different levels of gluten. Nima is designed to be sensitive at 20 ppm and above, however, Nima can sometimes detect gluten below 20 ppm which is the FDA standard for gluten free. Gluten below that level is technically safe according to the FDA but still may be too much for some.

While it's an extremely helpful and empowering tool, Nima isn't meant to replace what you're already doing or your doctor’s recommendations on how to avoid certain foods.

Newly diagnosed celiac patients may find Nima extremely helpful in transitioning to a gluten-free diet. The Nima result can help verify unclear ingredient names and allow you to check packaged foods not expressly labeled gluten-free.

Experienced celiac patients may also find Nima helpful in building confidence in eating outside the home. Many with celiac disease report social anxiety when eating out so they may avoid traveling or trying new restaurants. Nima can help provide you information to reduce your fears.

What are Nima's limitations?

Nima isn't able to detect gluten in soy sauce. It is always advisable to clarify all ingredients in meals that may contain soy sauce and avoid foods that include it

When gluten is fermented, the gluten protein is broken down into smaller pieces, making it impossible for Nima to detect it. 

It's possible the tests for gluten will someday find a solution to this problem, but for now Nima can't detect hydrolyzed gluten, or gluten in fermented products such as soy sauce or gluten-free beer.

How long does the test take?

Nima's testing takes approximately 3 minutes to detect gluten in your food. Just enough time to take and post a selfie with your meal!

How long the test takes may depend on how much gluten is present in a sample. If the gluten level is high, the test will take less time. If there are lower levels of gluten, Nima may take a bit longer to identify, making for a slightly longer test time.

Can Nima test for peanuts?

Nima does offer a separate sensor and capsules that test for peanuts. Currently only gluten sensors and capsules are available in Singapore.
