Measures IgE antibodies to nine tree nut allergens to help determine nut allergies.
This test measures immunoglobulin E (IgE) antibodies produced in the blood in response to certain peanut and tree nut allergens. It helps determine whether you have an allergy to almonds, Brazil nuts, cashews, hazelnuts, macadamia nuts, peanuts, pecans, pistachios, or walnuts. If levels for peanut, hazelnut, walnut, brazil nut, or cashew nut are abnormal, additional component panels are performed at no extra cost. A healthcare provider will review results with your medical history to diagnose an allergy and prescribe medication if needed.

Parents investigating potential food sensitivities in children. People considering an elimination diet and wanting data to guide which foods to remove.
What's Included
Preparation Required
No fasting required. Continue eating your normal diet for at least 2–4 weeks before testing — avoiding suspected trigger foods can cause false negatives. Inform the clinic of any antihistamines or immunosuppressants you're taking, as these can affect results.
Biomarkers Tested
11A group of proteins in blood including antibodies (immunoglobulins), transport proteins, and enzymes. Elevated globulin can indicate chronic infection, inflammation, or blood cancers. Calculated by subtracting albumin from total protein.
Measures IgE antibodies specific to almond.
Measures IgE antibodies specific to Brazil nut.
Specific IgE antibodies to cashew nut allergen.
Measures IgE antibodies specific to hazelnut.
Specific IgE antibodies to macadamia nut allergen.
Measures IgE antibodies specific to peanut.
Specific IgE antibodies to pecan nut allergen.
Specific IgE antibodies to pistachio allergen.
Specific IgE antibodies to walnut allergen.
Immunoglobulin E (IgE) is a protein associated with allergic reactions that is normally found in very small amounts in the blood. IgE functions as part of the body's immune system (its defence against 'intruders').
Includes a $6.00 Physician Service Fee. Klarna/Affirm payment options available.
