Tree nut allergy test

Tree nut allergies are among the most common allergies, according to Food Allergy Research & Education (FARE). The American Academy of Allergy, Asthma, and Immunology (ACAAI) reports that around 0.5% to 1% of the US population have a tree nut allergy.

Tree nut allergy testing involves either a skin prick test or a blood test to determine your body’s response to a variety of tree nuts.

What types of tree nut allergy tests are there?

Two types of testing options can be used to test for tree nut allergies, according to the Asthma and Allergy Foundation of America (AAFA)—skin tests and blood tests.

A skin test involves injecting a small amount of tree nut protein under the skin, and then observing for a reaction. These tests are typically the preferred method for diagnosing most allergies, according to the AAFA as these tests are highly accurate and can provide results quickly.

Blood tests are also used to test for tree nut allergies. These tests measure the levels of immunoglobulin E (IgE) antibodies in the blood, which are produced in response to exposure to allergens such as tree nuts. Blood tests are usually used to confirm an allergy after a positive skin test, according to the AAFA.

When should I get a tree pollen allergy test?

You should consider allergy testing if you experience signs and symptoms of allergies after being in an environment with tree nuts. According to the AAFA, symptoms of allergies include:

  • Sneezing
  • Runny nose
  • Itchy eyes
  • Congestion
  • Cough or wheezing
  • Hives
  • Itchy skin
  • Trouble breathing (a severe sign that is an emergency)

Additionally, if you have a personal history of other allergies or a family history of tree nut allergies, asthma, or eczema, you may be more likely to have a tree nut allergy and should consider getting tested.

What to expect with a tree nut allergy test

There is usually little to no preparation needed for allergy testing. Your healthcare provider can provide specific details if there are any special considerations you need to take before testing.

Sometimes, your testing provider will request that you refrain from taking certain medications like antihistamines before testing, according to the AAFA.

Finding a tree pollen allergy test

Most allergy testing can be done with a referral from your primary care provider to see an allergist—a physician who specializes in testing for and managing allergies.

If you need help finding allergy testing locations you can use the healthcare provider directory on Solv’s website. Solv allows you to contact providers individually to learn more about their services and allows you to book a same-day or next-day appointment from its website.

Can I get a tree nut allergy test at home?

There are many at-home allergy test kits available for purchase. The sample collection varies, depending on the brand of test, and results are usually available within a few days to a few weeks.

It is important to note that while at-home allergy test kits may be convenient, they may not be as accurate as tests performed in a healthcare setting. If you receive a positive result from an at-home test, it is recommended that you follow up with a healthcare provider for confirmation and further evaluation.

Additionally, if you are experiencing severe allergy symptoms, the AAFA notes that it is more appropriate to get tested in a healthcare setting, where you can discuss your potential treatment options with a healthcare provider.

Cost of tree nut allergy tests

The cost of allergy testing—including tree nut testing—can vary depending on several factors, including the type of test being performed, the location of the testing facility, and your insurance coverage.

The average cost of tree nut allergy testing in the US is around $149-$162, according to

Tree Nut Allergy Test FAQs

Find answers to the most commonly asked questions about lab tests.

Allergic reactions to tree nuts can occur within minutes to a few hours after consuming the food, according to the Food Allergy Institute. However, in rare cases, symptoms may not appear until several hours later.
Allergies can develop at any time in your lifetime, according to the Mayo Clinic and the AAAAI. Even if you were not previously allergic.
There is no cure for tree nut allergies, however, there are some treatments for managing symptoms. Additionally, immunotherapy (also known as “allergy shots”) has been proven effective in helping to reduce the severity of allergic reactions. Immunotherapy works by introducing small amounts of the allergen into your body, which helps to build tolerance. The best treatment for tree nut allergies is to avoid contact with the tree nuts you are allergic to, which also means avoiding many packaged foods that may contain tree nuts. The FDA requires food products to list potential allergens on the label, including tree nut allergens. If you have a severe allergic reaction to tree nuts, you should carry an Epi-Pen with you in case of accidental exposure.
An oral food challenge (OFC) is a diagnostic test that is used to determine if someone is allergic to a specific tree nut, according to the AAAAI. During the OFC, a small amount of the tree nut is given to the person to eat, under the supervision of a medical professional in a controlled environment such as a hospital or clinic. The amount of the nut is gradually increased over time, while the person's vital signs and symptoms are closely monitored for any signs of an allergic reaction. The OFC is considered the gold standard for diagnosing a tree nut allergy because it provides the most accurate information about a person's allergy, according to the Mayo Clinic. However, it should only be performed by a trained medical professional with the necessary equipment and medications to treat any severe allergic reactions that may occur during the test. Before an OFC is performed, the person will typically undergo skin prick testing and/or blood testing to determine if they are at a high risk of having an allergic reaction during the challenge. If the results of these tests are negative, an OFC may not be necessary. If the tests are positive, an OFC may be recommended to confirm the allergy and determine the severity of the reaction.
