These Are the Best At-Home Food Sensitivity Tests

We chose cerascreen as the best overall pick because it has three test options, an app that makes results a breeze to read from a mobile device, and great overall value.

Like most at-home test kits, cerascreen’s food sensitivity kits require a finger prick sample. After collecting it with the materials inside the kit, you are instructed to activate the test in the safe and secure “my cerascreen” portal on the cerascreen website or app. From there, use the prepaid packing label to send the kit to its partner lab.

The lab analyzes samples for specific Immunoglobulin E (IgE) and Immunoglobulin G4 (IgG4) antibody reactions. The results report is completely personalized and will clearly state if you have any elevated levels of specific IgG4 antibodies—indicating that you could be sensitive to certain foods, drinks, or additives. Along with the reaction report, cerascreen provides nutrition tips on keeping a balanced diet with food sensitivities.

Its food sensitivity kits also test for food allergies so you can get all the answers to your possible food-related questions in one go. The cerascreen test kit option that includes food sensitivity testing starts at approximately $150.

We chose Everlywell because it's a tried and true at-home test kit company with comprehensive results.

Everlywell makes at-home testing easy with a model that works similar to cerascreen’s. After you place an order for the test and it arrives at your doorstep, you unpack it all and register your kit on the Everlywell portal with the unique ID that is included in the box. This ensures your data is kept anonymous at the lab. Then, collect the sample via a finger prick method using the items included in the test kit box and mail it back to its partner lab with the prepaid shipping label.

Everlywell notes that your results will become available on your secure online in five to seven business days. The results are formatted in a way that is not just personalized, but super easy to understand. The report, similar to cerascreen, includes actionable steps to help guide you in treating your specific health issue.

While Everlywell doesn’t offer a one-on-one phone call with a nutrition consultant, it does offer a complimentary webinar led by a health care professional to answer any outstanding questions. The company's basic food sensitivity test is available for approximately $160 and an extensive food sensitivity test is available for around $260.

YorkTest is the only food sensitivity test on the market that tests for IgG reactivity and also offers bundle packs for couples and families alike.

YorkTest, like Everlywell and cerascreen, utilizes a finger-prick blood sample to test antibody reactivity to certain foods, drinks, and additives.

YorkTest markets its tests specifically for IBS sufferers and includes a result guidebook along with a food and drink diary to support your food sensitivity elimination journey after you receive your test results. The results are easy to understand and are broken down into three categories—normal reactivity, borderline reactivity, and high reactivity. They can also be easily printed and shared with your primary care physician for extra support.

The company stands out because it's the only at-home food sensitivity testing company that offers a kit specifically for children. Its junior food intolerance test is recommended for children aged 2-17 and tests Immunoglobulin G (IgG) reactions to more than 100 food and drink ingredients.

Depending on which kit you choose, you can test for more than 200 items. The premium test kit costs approximately 200 British Pounds, and comes with a free 30-minute consultation with a nutritionist to discuss the next steps after you receive your test results. YorkTest doesn’t have an online portal, so your results are sent to you via email a few days after you send in your sample back. A customer care team is available for guidance every step of the way.
