Tree Nut and Peanut Allergy Test

Comprehensive screening for 9 tree nut and peanut allergens.

The Tree Nut and Peanut Allergy Test is a blood test that measures IgE antibodies to nine common nuts, including tree nuts and peanuts. This test can provide valuable insights into your body's immune response to these allergens. 


Tree nut and peanut allergies are among the most common food allergies and can cause severe reactions in some individuals. Understanding your body's response to various nuts can be crucial for managing your diet and health. This test offers a proactive approach to identifying potential allergies before they lead to unexpected allergic reactions. 


Note: Having measurable IgE for a particular allergen does not guarantee that you will have an allergic reaction when exposed to it. In general, higher IgE levels are associated with a greater chance of having a true allergy but do not predict how severe your allergic symptoms could be. IgE testing is not considered sufficient to diagnose an allergy on its own. Results should be shared and discussed with a healthcare professional before making an allergy diagnosis.

What's Tested
  • Nuts included in this test

    This Tree Nut and Peanut Allergy Test measures IgE antibodies to nine common nuts: almond, brazil nut, cashew nut, hazelnut (filbert), macadamia nut, peanut (whole), pecan nut, pistachio and walnut. The test measures your body's immune response to these nuts, helping identify potential allergies that may require further attention or dietary changes.

    If your initial blood test shows IgE levels of 0.10 kU/L or higher for brazil nut, cashew, hazelnut (also called filbert), peanut (whole), or walnut, an additional test will automatically be performed for that nut. This second test looks for specific proteins called “components” in those nuts, providing more detailed information about your allergy risk.

Why Consider This Test

Question mark icon

Unexplained allergy symptoms

If you've experienced unexplained symptoms, this test can help identify potential nut allergens. Symptoms like hives, itching, or difficulty breathing could indicate a possible tree nut or peanut allergy.

common disorder icon

Family history of nut allergies

Tree nut and peanut allergies can run in families. If you have multiple family members with known nut allergies or you have other allergy conditions, this test may help determine if you're at risk. It is important to share your results with a healthcare provider or an allergist to determine the next steps.

Proactive health management

Some people choose testing to learn about possible sensitization (which means your immune system reacts to a particular substance, but you may not have symptoms), especially if they have a family history or unexplained symptoms. Discuss results with a healthcare provider or an allergist before making any dietary changes.
