What is this test?

This blood test measures allergen-specific IgE antibodies against a mixture of several tree allergens. The exact allergens included in Tree Allergen Mix 6 may vary by laboratory or test manufacturer.

Why might I need this test?

Your clinician may order it to evaluate suspected tree-allergy symptoms such as sneezing, watery eyes, wheezing, or hives. It may also help identify which tree allergens are likely to trigger an immune response.

How is the test performed?

A blood sample is drawn and tested for IgE antibodies to the allergens in the mixture. The result is reported as a concentration or laboratory-specific measurement that may be classified as negative, equivocal, or positive.

How do I prepare for the test?

This test usually requires no fasting or other special preparation. Antihistamines generally do not affect serum IgE testing, but tell your clinician about any medicines or recent allergy testing before the sample is collected.

Reference range

Adult: 10-40 U/LN/A

Frequently asked questions

Does a positive result mean I am allergic to trees?
It indicates that your immune system has produced IgE antibodies to one or more tree allergens in the panel. A clinician must correlate this finding with your symptoms to determine whether you have a clinical allergy.
Can this test show exactly which tree caused my symptoms?
Not always. Because the test uses an allergen mixture, the laboratory may report antibodies to the mix or to individual components. Your clinician may recommend more specific testing based on your history.
Is skin-prick testing needed as well?
Sometimes. Serum testing can be useful when skin testing is difficult or unsafe, and the two tests provide complementary information. Your allergist can decide whether additional testing is appropriate.
