Comprehensive Food Allergy Test

Test your IgE immune response to 17 common food allergens.

Our Food Allergy Test measures your immune response to some of the most common food allergy triggers including lactose, shellfish and nuts. It detects Immunoglobulin E (IgE) antibodies, which are released by the immune system in response to allergens. Along with your food allergy symptoms and history, this food allergy test provides insights into how your body reacts to common foods. These results can help guide you toward better dietary choices and support conversations with your healthcare provider or allergist.


 
Note: This test is not intended for individuals who have experienced severe allergic reactions to any of the foods listed on this panel—please consult a healthcare provider or allergist immediately in those cases. A positive IgE result doesn’t always mean you’ll have an allergic reaction, and higher levels don’t predict how serious symptoms might be. IgE testing alone cannot diagnose a food allergy, so results should always be reviewed with a healthcare professional before making any dietary changes. Results from this test should be interpreted in the context of your medical history with a healthcare provider or an allergist.

What's Tested
  • Foods included in this test

    This test screens for reactions to many common foods, including:

     

    • Tree Nuts: Almond, Brazil nut, cashew, hazelnut, peanut, walnut
    • Seafood: Codfish, salmon, tuna, scallop, shrimp
    • Dairy & Eggs: Milk, egg white
    • Grains & Seeds: Wheat, sesame seed, soybean
    • Others: Wheat protein (gliadin)

     

    If IgE antibody levels for milk, egg white, peanut, hazelnut, walnut, cashew nut, Brazil nut, sesame seed, or wheat are elevated, additional component testing will automatically be performed on the same sample to identify specific proteins that may trigger an allergic response. This reflex testing can support more informed discussions with your healthcare provider.

FAQ

  • Symptoms of an allergic reaction to foods may involve the skin, gastrointestinal tract, cardiovascular system, or the respiratory tract. Common symptoms are3:

     

    • Stomach cramps
    • Vomiting
    • Itchy mouth or lips
    • Hives or rash
    • Shortness of breath
    • Wheezing
    • Repetitive cough
    • Tight, hoarse throat; trouble swallowing
    • Dizziness or feeling faint
    • Swelling of the tongue and/or face, affecting the ability to talk or breathe
  • People who are allergic to proteins in specific foods develop IgE (immunoglobulin E) antibodies to those food proteins. IgE is a protective blood protein that is produced when you’re exposed to a substance that your body views as a threat. Therefore, measurable IgE may indicate the presence of an allergy.

     

    If you suspect a food allergy, share your test results with your health care provider or allergist, who will take your family and medical history, and use this information to determine if a food allergy exists.
