What is this test?

Tree Allergen Mix 8 IgE is a blood test that measures allergen-specific IgE antibodies against a mixture of eight tree allergens. These antibodies are part of the immune response to tree pollen or other tree-derived allergens.

Why might I need this test?

Your clinician may order this test if you have symptoms such as sneezing, runny nose, itchy or watery eyes, wheezing, or hives that could be related to tree exposure. It can help identify likely tree allergens, especially when the specific trigger is unclear.

How is the test performed?

A blood sample is collected and analyzed in a laboratory to measure IgE antibodies to the tree allergen mixture. Results may identify which components of the mixture show a positive reaction.

How do I prepare for the test?

Fasting is usually not required. Tell your clinician about any allergy testing, immunotherapy, biologic medicines, or medicines that suppress IgE because they may affect the results.

Reference range

Adult: 10-40 U/LN/A

Frequently asked questions

Does a positive result mean I am allergic to trees?
It indicates allergen sensitization, but a positive result does not always mean the allergen is causing your symptoms. Clinical history and sometimes additional testing are needed to diagnose a specific tree allergy.
Can this test show which tree allergen is causing my symptoms?
The laboratory may report which components of the eight-allergen mixture reacted. Your clinician will compare those results with the types of trees and pollens you encounter and the timing of your symptoms.
Is skin-prick testing or total IgE testing also needed?
These tests may be used for further evaluation. Total IgE shows the overall amount of IgE in the blood, while skin-prick testing and specific IgE testing assess reactions to individual allergens.
