Last Updated: May 14, 2019

Food sensitivities and allergies are increasingly common in the modern world. In fact, 10% to 20% of the population reports suffering from some form of food allergy. Though many of these reports are not accurate, modern testing techniques are making it easier than ever to identify foods that are affecting the quality of our lives. This guide is designed to help you find the food sensitivity test that is best for you.

Summary of our findings:

What is food sensitivity testing?

First, it is helpful to make a distinction between two distinct terms that are often used interchangeably: food allergies and food sensitivities.

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.

Food sensitivities, on the other hand, are for the most part non-life-threatening, but can make you feel very uncomfortable. Symptoms of food sensitivity include things like nausea, hives, and trouble breathing. In response to some foods, the body produces IgG antibodies in response to the antigens.

By measuring the number of IgG or IgE antibodies in a small blood sample, tests can make predictions about reactions you may have to certain foods.

Different testing options & recommendations

IgG Food Sensitivity Tests

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.

Our top recommendation:

EverlyWell’s Food Sensitivity Test [See latest price] Currently, EverlyWell is offering our readers 15% off all tests. Just use the coupon code: INNERBODY15 upon checkout.

EverlyWell’s Food Sensitivity Test assesses IgG reactivity levels to 96 different foods commonly found in Western diets. For each food, you will get a 0 to 3 rating, with 0 being the lowest reactivity and 3 the highest reactivity.

All your food ratings are analyzed together to create a thorough report that will give you tailored suggestions for next steps and help in creating a trial elimination diet.

EverlyWell’s test is perhaps the most convenient food sensitivity test available–the entire test can be taken without leaving your home. Here are the four easy steps:

IgE Food Allergy Tests

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.

Our top recommendation:

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 done 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.
