Criteria For Best Food Allergy Tests

Test for Common Foods That Cause Allergies:

Peanuts and shellfish are the most obvious food allergies, but there are many more. The more foods a test measures, the more information you’ll get..

Please note: the general reader often means the same thing when they talk about ‘intolerances’ and ‘allergies’ (for more info about the differences between allergies and intolerances see discussion further below).  We include one test for intolerances.

Certified Labs:

We selected blood test vendors that had been certified by the Clinical Laboratory Improvement Amendments (CLIA). We also considered their third-party assessments and Better Business Bureau ratings for each service.


We searched for websites that provide thorough explanations of tests, offer results in an easy-to-understand format, enable you to track health developments as you order additional tests, and deliver rapid outcomes.

Best For Intolerances: Intolerance Lab

  • Price = $55 (€49)
  • Location: At Home
  • # of Reviews = 1608
  • Average Rating = 4.4/5
  • Better Business Bureau Rating = N/A

Intolerance Lab has two main advantages: price and at home testing using your hair.

In terms of price, you’re not going to find a lower price on the market.

Intolerance Lab’s test is hair-based. Instead of going to a lab and getting your blood drawn, you can pluck a few hairs from at home.

Intolerance Lab has a database of 700+ foods they will test your hair against.

Please note: As noted above, allergies and food intolerances are different.  This is an intolerance test, NOT a food allergy test. 

If you have a food allergy – for example, if you eat peanuts and hyperventilate – then see other tests below. For more info about the differences between allergies and intolerances see discussion below.

If you’re like many people who use allergies and intolerances interchangeably, then Intolerance Lab is a great first step in our opinion.

Why Do I Need Food Allergy Testing?

The most dangerous health problem related to food allergies is anaphylactic reactions or shock.

 Anaphylactic shock is where the body goes into shock after being exposed to the allergen.

Anaphylactic shock affects the whole person.  Symptoms can include:

  • difficulty breathing
  • swollen throat
  • dizziness
  • fast heart rate
  • feeling faint or lightheaded

Some of the symptoms can occur just seconds after an allergic reaction.

However, many allergy symptoms are more mild.

The skin, gastrointestinal system, cardiovascular system, and respiratory tract may all be affected by an allergic response.

The following are some of the symptoms that might show up in cases of mild allergic reactions:

  • Vomiting is the most common side effect
  • Stomach cramps are another frequent symptom
  • Coughing repeatedly is a sign of infection, which can be a complication of a food allergy
  • Itchy skin, also called dermatitis, is a very common sign that you might be having an allergic reaction to something that you ate
  • Rashes, which can be either itchy or bumpy, may develop on the skin
  • Watery and bloodshot eyes may occur as well

How Common Are Food Allergies?

Food allergies are quite common. According to food allergy research, they currently affect 5% of adults and 8% of children worldwide.

Whether a youngster will inherit his or her parent’s food allergy cannot be predicted.

Surprisingly, while any food might induce an allergy, only a small number of frequent foods account for the majority of allergies.  Remember?  The Big 8 account for about 90% of allergies in the U.S.

What’s the Difference Between Food Allergies and Food Intolerances?

Food allergies and food intolerances are both problems that can occur after eating foods.

Some people confuse the terms “food allergy” and “food intolerance.  However, the two conditions are different. A food allergy is an immune system response to a specific food.

However, a food intolerance does not involve the immune system.

A food intolerance is a problem that occurs when the body cannot digest a specific food or drink – but are not fatal or that dangerous.

Food intolerances are much more common than food allergies. They affect an estimated 50% of the population.

Symptoms of food intolerances can include:

  • Diarrhea
  • Nausea
  • Vomiting
  • Stomach cramps
  • Headache
  • Fatigue

Food allergies, on the other hand, are much less common. They affect about only one in every 50 people.

The symptoms of food allergies can be very serious and include:

  • Anaphylactic shock
  • Hives
  • Itching
  • Swelling of the lips, face, or throat
  • Wheezing
  • Difficulty breathing
  • Coughing

Is There Anything Else I Need to Know About Food Allergy Testing?

It can be difficult to avoid foods that cause allergies. However, there are lifestyle and home remedies that are common sense.

The most effective ways for preventing allergies are avoiding foods that cause the symptoms.

  • Always check your food labels for substances that can be allergens.
  • Read labels to avoid common food allergens that might affect you personally, such as meat, poultry, shellfish, soy and wheat. 
  • Please know in restaurants or social groups, there are always chances that you could be served something that you are allergic to.
  • If you have had a severe allergic reaction in the past, be sure to carry appropriate medical materials like an epi-pen on your body or purse before going out.

There are also other food allergy tests like the skin prick test or an oral food challenge if you want an alternative food allergy diagnosis. .

The skin prick test involves injecting microscopic amounts of food underneath the skin to see if the skin reacts, usually with a rash.

The oral food challenge is where you ingest an amount of food under controlled circumstances to determine if your body reacts.

Sometimes you also just put the food underneath your lower lip to see if you react.


The most effective approach to avoid allergic reactions to a food is to stop eating anything that produces symptoms or has an impact.

However, even if you attempt to avoid them, you may come into contact with foods that can cause reactions. An antihistamine might help with mild or severe allergies such as those caused by food allergy.

Antihistamines, on the other hand, are ineffective in treating severe allergies. A life-threatening allergic reaction is likely to necessitate injections using a syringe or to the hospital. The vast majority of allergy patients possess autoinjectors for EPI-p administration.
