Food sensitivities and allergies are increasingly common in the modern world. Up to 8% of children have food allergies, while the percentage of allergy sufferers rises to nearly 11% among adults. However, the rate of food sensitivity and intolerance among people is considered by the medical community to be significantly higher. According to research, for instance, 65% of teenagers and adults deal with a degree of lactose intolerance.
Thankfully testing techniques are making it easier than ever to identify foods that affect the quality of our lives. We examined all of the direct-to-consumer food-related tests currently on the market in 2021 and two companies rose to the top: Everlywell and Personalabs.
We’ll dive into the various tests offered by these companies and provide recommendations on which of the tests could be a good choice for you. Along the way, we’ll also help you understand the differences between food sensitivity, allergy, and intolerance.
Before we dive deeper, here are the pros, cons, and key conclusions about investing in at-home food sensitivity tests. We recommend Everlywell for food sensitivity tests and Personalabs for food allergy testing.
- Convenience - Take the test easily at home
- Painless - A simple finger-prick is all it requires
- Extensive - You can check for sensitivity to nearly either 100 or 200 foods
- Accuracy - Our top pick (spoiler: Everlywell) boasts 90-95% accuracy with certified 3rd party lab partners
- Discounts - Everlywell offers our visitors a 20% discount with the promo code REFER20
- Insurance may not cover any cost from the testing
- You should still consult with your primary care provider about results
- Tests not available in NY, NJ, or RI
While these tests aren’t meant to replace your primary care provider, if you suspect you may have a food sensitivity or intolerance, there isn’t an easier way to start learning valuable information with Everlywell’s food sensitivity test. Think of this as the start of your journey toward a solution rather than the end of the journey. The test results provide excellent starting points for eliminating foods and reintroducing them later to verify that you’ve identified all of your problem foods. And if you’re wondering whether you have a food allergy – which is potentially much more severe and even life-threatening – you could kick off this exploration by buying a food allergy test from Personalabs. These two types of tests measure different immune reactions in the body. Read on for more information.
Everlywell is our top choice for at-home food sensitivity testing. It conveniently checks sensitivity to a wide variety of foods and gives a clear report of results.
The test from Everlywell offers you a comprehensive assessment of IgG reactivity levels for 96 different foods. You can trust in the accuracy of results when testing with Everlywell, one of the most respected at-home test providers.

Headaches… Problems with digestion… Pain in your joints… Skin rashes and breakouts… Coughing and chest tightness… Did you know that what you’re eating could be responsible for these symptoms and others?
You may think you’re eating a healthy diet - and you very well might be. But even healthy foods can trigger a response in our bodies. The nature of the reaction is where we draw distinctions between food allergies, food sensitivity, and food intolerance.
Food allergy, sensitivity and intolerance are three terms used to describe problems in our reaction to certain foods. We often don’t properly distinguish between them, even though they are very different issues.
Food allergies are severe and can be life-threatening. You may have heard stories about a child becoming fatally ill after mistakenly eating something that contained peanuts. That is an allergy. In response to food allergies, the body produces IgE antibodies to fight off the antigens. IgE stands for immunoglobulin E. The symptoms of an allergic reaction usually present themselves within minutes of eating the food. Symptoms vary but might include hives, difficulty breathing or anaphylactic shock (in which your blood pressure plummets and you can’t breathe).
Food sensitivity isn’t life-threatening, but can be quite serious or make you feel very uncomfortable and unwell. Symptoms of food sensitivity - including things like nausea, hives, headache, and joint pain - can appear hours or even a few days after eating the food. When you’ve got a food sensitivity, your body’s immune system responds to the offending food by producing IgG antibodies, in addition to other possible responses. This is a different response than how our bodies react when we’re allergic to a food.
In contrast to the two others, food intolerance doesn’t trigger an immune response. Intolerance describes a situation in which our body lacks a certain digestive enzyme, for instance, or for some reason doesn’t absorb certain nutrients as it should. Symptoms of food intolerance can be disruptive and make you feel unwell, also. The most common intolerance is lactose intolerance, which often results in heartburn, gas, bloating, and/or diarrhea after eating dairy products. Sometimes these symptoms occur within an hour of eating the substance, but other times they could be delayed (up to two days).
Here’s a handy chart for reference, breaking down the differences between the three.
|Test available||Personalab||Everlywell||Breath test|
|How long until symptoms?||Often just minutes later||Anywhere from a half hour to days later||Anywhere from less than an hour to 2 days later|
|Severity?||Severe - possibly life-threatening||Not life-threatening, but significant||Unpleasant but not life-threatening|
|What kind of response triggered?||Immune - IgE||Immune - IgG and more||No immune response|
|How common is it?||5-10% of children; 3-4% adults||Unknown but very common||Possibly 65% of people|
IgG food sensitivity tests are best for those who are looking for recommendations on how they can change their diets to improve their health and well-being. Common symptoms of food sensitivity include headaches, fatigue, stomach pain, indigestion, skin issues, joint pain, and sometimes just a feeling of being unwell.
One of the first of its kind, this at-home test assesses IgG reactivity levels for nearly 100 different foods.

Larger test option
Everlywell also offers its new Comprehensive Test for not quite double the price of its more affordable, standard food sensitivity test recommended above. The comprehensive test checks twice as many foods (a total of 204 foods).
In the past, we also recommended Wellnicity as a runner-up to Everlywell, because they offered a very comprehensive test of nearly 200 foods for double the price of Everlywell’s standard test. But now that Everlywell offers a larger test as well and our testers had difficulties ordering from Wellnicity this year, we no longer recommend them. We advise sticking to the more established company - Everlywell.
Everlywell’s comprehensive test includes all foods in the lower-priced standard test as well as the additional 100+ other foods listed alphabetically below. We don’t recommend this test over the standard test unless some of the foods below are a part of your diet (in which case, you might want to opt for this test instead of the other).
Foods included in the comprehensive but not the standard test:
Aloe vera, Anchovy, Anise, Apricot, Artichoke, Arugula, Baking powder, Bamboo shoots, Beet, Black currant, Blackberry, Branzino, Brazil nut, Brussels sprout, Buckwheat, Butter, Butter lettuce, Caper, Carob, Carp, Casein, Cayenne pepper, Chamomile, Chard, Cherry, Chestnut, Chickpea, Chicory, Chili pepper, Chive, Cilantro, Cloves, Cranberry, Crayfish, Cumin, Curry, Date, Duck, Eel, Emmental cheese, Fava bean, Fennel, Fig, Flaxseed, Goat cheese, Goat milk, Gooseberry, Grape leaf, Hazelnut, Herring, Honeydew melon, Hops, Horseradish, Jerusalem artichoke, Kefir, Key lime, Kidney bean, Kiwi, Leek, Lentil, Licorice root, Lychee, Macadamia, Mackerel, Mango, Marjoram, Millet, Mint, Mung bean, Navy bean, Nectarine, Nutmeg, Octopus, Pacific oyster, Papaya, Parsley, Peppermint, Perch, Pike, Pine nut, Pistachio, Plum, Pomegranate, Poppy seed, Prawn, Processed cheese, Quail, Radish, Raisin, Rapeseed, Raspberry, Red cabbage, Rosemary, Saffron, Sage, Shallot, Sheep cheese, Sheep milk, Shiitake mushroom, Snow pea, Spelt, Squid, Thyme, Trout, Turnip, Vanilla, Whey, and Zucchini.
IgE food allergy tests are for those looking to diagnose or confirm a specific allergy or those who have a family history of allergic reactions. Allergic symptoms vary significantly from person to person but can include nausea, hives, trouble breathing or swallowing, and vomiting.
The most common foods that cause allergic reactions are tree nuts, peanuts, milk, eggs, soy, fish, wheat, and shellfish.
This blood test helps diagnose allergies to the most common allergenic foods, including tree nuts, peanuts, milk, eggs, soy, fish, and wheat.
Personalabs specializes in comprehensive blood tests and partners with over 2,300 labs nationwide. Chances are there is a partner lab convenient to where you live.
Personalabs’ Food Allergen Profile (Basic) Blood Test [see latest price]
This fairly comprehensive test checks for allergic reactions to most common allergenic foods, including codfish, cow’s milk, egg whites, peanut, soybean, and wheat.
Personalabs also offers a more comprehensive test confusingly named the Allergen Profile Food Blood Test [see latest price]. It tests for everything the “Basic” test does, but adds almond, cashew nut, hazelnut, salmon, scallop, sesame seed, shrimp, tuna, and walnut. In general, we believe that the Basic test is the best starting point unless you don’t want to leave any stone left unturned (and don’t mind paying more).
While it’s not quite as convenient as Everlywell’s, Personalabs’ testing process is still very easy and works very well. Here are the four steps in the process:
1) Select and order your test from the Personalabs.com website.
2) Print out your order form.
3) Bring your order form to one of Personalabs’ 2,300 lab testing locations. Appointments are not necessary but are recommended. The testing process usually takes less than 10 minutes. To confirm that there is a convenient testing location near you, check here.
4) Wait for your results to be posted online. This is usually completed within 48 hours after testing. You will have access to a free doctor’s consultation if you have any questions about your results.
Another thing we like about Personalabs is that it offers less expensive tests that only test for specific types of food. These tests are great if you already have an idea about which specific food you are most likely allergic to. Examples of such tests include the Allergen Profile - Milk Blood Test, the Allergen Profile - Grain Blood Test, and the Allergen Profile - Shellfish Blood Test. A list of all tests offered can be found here.
