As many as 8% of children and 11% of adults are suffering from some sort of allergy, and even a higher percentage experience some type of intolerance. With a range of awful, and similar, symptoms, both intolerances and allergies can be a nightmare to deal with. 

The best way to deal with these conditions is to avoid the food or environmental irritant that’s causing them. That’s why these at-home tests have become so popular in recent years. But, seeing as so many of them have popped up on the market, they’re not all totally reliable.

So we took the top allergy and intolerance tests on the market and narrowed down the best of the best. In this article, we’ll lay out the best 3 test kits for anyone suffering from the symptoms of an environmental or food allergy or intolerance.

The Difference Between an Allergy and an Intolerance

While environmental and food allergies and intolerances may cause a lot of similar symptoms, the two conditions are quite different. Most environmental and food reactions are caused by intolerances, but allergic reactions can be a lot more severe. For this reason, knowing whether your symptoms are the result of intolerances or allergic reactions is incredibly important.

The main differences between allergic reactions and intolerances are:

Environmental or Food Allergy: Allergies tend to be far more severe than intolerances, and a food allergy can even be deadly in some cases. Unlike food intolerance, a food allergy causes an immune system response which could affect a number of your body’s organs. This response can be severe, and, in some rare cases, such as seafood or peanut allergies, it can be life-threatening.

Environmental allergies are not nearly as serious as a food allergy could be, but they’re still rather unpleasant. They’re caused by something in your surrounding environment, such as dander or pollen, rather than something you’ve ingested. These allergies also cause an immune response and have a number of unpleasant symptoms, including:

  • Fatigue
  • Shortness of breath
  • Sneezing
  • Itchy eyes
  • Runny nose
  • Headaches
  • Wheezing
  • Itching

For those with asthma, an environmental allergy can be especially severe, and, in some rare cases, even life-threatening.

Environmental or Food Intolerance: Intolerances tend to be far less severe than allergies, and aren’t life-threatening. Those with these food sensitivities can usually ingest small amounts of the offending food without much issue. The symptoms of food intolerance can vary quite a bit depending on the type of intolerance. Some of the different causes of food intolerances include:

  • Inability to Digest Lactose — This is when you lack the enzyme needed to digest lactose. Known as lactose intolerance, some of the symptoms include diarrhea, gas, cramps, and bloating.
  • Food additive sensitivity — Some people are incredibly sensitive to certain common food additives, such as sulfites or preservatives. This intolerance can lead to trouble in breathing, including asthma attacks in those affected.
  • Irritable bowel syndrome — Certain foods can lead to irritable bowel syndrome (IBS) in sensitive populations. While the cause of IBS isn’t fully understood, it’s known that diet and sensitivities to certain foods play a role. Some IBS symptoms include constipation/diarrhea, abdominal pain, bloating, gas, and cramps.
  • Celiac disease — This condition is caused by ingesting gluten, a protein that is commonly found in wheat and some other grains. While considered a gluten intolerance, celiac disease does cause an immune response similar to an allergy. The best treatment for this condition is eliminating gluten from your diet.

Intolerances to environmental items have many similar symptoms to environmental allergies and are often confused. Where they mainly differ is that an allergy involves the immune system, while an intolerance does not.
