Food intolerance affects around
Many at-home tests are reliable and effective. But there can be big differences in the types of foods they test, the cost, and the support they provide for making diet changes.
Below is a comparison of tests and how to figure out which one is best for you.
Food sensitivity tests typically check how your immune system responds to different types of food.
Currently, there are no at-home testing options for food allergies, but there are reliable options that test for sensitivities.
Food sensitivity tests help you discover the foods triggering adverse symptoms, such as gas and bloating. Many of the testing companies offer actionable steps to help you reduce your symptoms.
The tests vary based on the following:
- Sample collection. Collections can come from hair strands, cheek swabs, or blood samples.
- What’s tested. Tests offer a range of results, from sensitivities to your genetic response to food, exercise, and more.
- Type of support. Not all companies offer support for making changes, but many of them offer customized information to help improve your health.
If you believe you have a food sensitivity or have unexplained symptoms, a food sensitivity test could help provide some answers.
Elimination diets that cut out foods and reintroduce them to test symptoms take time, and they are often difficult to correctly follow.
A test can help you narrow down which foods trigger your symptoms, helping you find relief sooner.
You should also discuss any symptoms you experience with your doctor.
We considered many factors when choosing this list of the best at-home food sensitivity tests, including:
- Comprehensive testing. How many foods do they test? What kind of support does the company offer after you receive results?
- Result speed. How long does it take to get results?
- Reputation. We chose products based on customer reviews and experience.
- Cost. We considered the pricing for the initial test and any ongoing fees or upsells.
- Price: $159–$259
- Sample type: Finger prick blood sample
- Results: Within 5 days
Each purchase comes with instructions, collection materials, prepaid shipping, and the options for both digital and printable results.
Everlywell offers support to provide actionable steps for your results, including a group webinar with a healthcare professional to answer questions. Each test is reviewed by an independent board certified physician.
(Note that the Everlywell test uses immunoglobulin G (IgG) testing, which clinicians generally advise against, as this method is not scientifically proven and may provide inaccurate information in diagnosing food sensitivities.)
The company offers a partial refund if results haven’t been released and your purchase is less than 30 days old.

You can also use raw data for your health report if you took a previous DNA test from AncestryDNA, 23andMe, or MyHeritage.
Vitagene sets you up with a personal online coach to help you work on changes based on the information gained from your test.
Note the company tries to upsell supplements to you based on the results of your DNA test.

The company guarantees results by the end of 8 weeks, or they’ll refund your money.
Best breath test
- Price: $179
- Sample type: Breath test
- Results: Immediate, but need to be tracked consistently
The FoodMarble AIRE device is the first personal breath test device. It works by testing fermentation and hydrogen levels after eating food. This can indicate sensitivities and intolerances to certain foods.
This test requires the most work from you because you’ll need to consistently use the device. You’ll also need to track food and health behaviors in the app.
Over time, you’re able to see trends to better understand any food sensitivities you have. From there, you can make changes to your diet to ease symptoms.
Are food sensitivity tests covered by insurance?
No. Most at-home food sensitivity tests aren’t covered by insurance.
Your insurance may cover food sensitivity tests ordered through your doctor, but that’s not guaranteed.
Are at-home food sensitivity tests reliable?
Many companies work closely with clinical doctors and researchers to create accurate results for patients.
Over the past few years, at-home food sensitivity tests have only continued to become more reliable and advanced.
How often should you get tested?
It’s common for food sensitivities to change over time. Food sensitivity can be tested every 1 to 2 years, or sooner if you notice changes in symptoms.
Can an at-home food sensitivity test diagnose a food allergy?
No. Currently, at-home tests cannot be used to diagnose food allergies.
Experiencing the symptoms of food intolerance regularly can be exhausting. At-home food sensitivity tests can take the guesswork out of elimination diets and provide you with a more focused plan.
If you experience sudden changes in symptoms, it’s best to discuss these with a healthcare professional.
But at-home tests can help support your health by guiding you to the possible causes of your symptoms.
