What is this test?
This test measures tree-specific IgE antibodies in a blood sample. Tree Allergen Mix 10 combines several tree allergens, although the exact allergens included may vary by laboratory.
Why might I need this test?
Your clinician may order this test to evaluate a suspected allergy to trees or tree pollen, especially if you have symptoms such as sneezing, itchy or watery eyes, wheezing, or a rash after exposure.
How is the test performed?
A blood sample is collected and tested in a laboratory for IgE antibodies against the allergens in the mixture. The laboratory may use a radioallergosorbent or another validated immunoassay method.
How do I prepare for the test?
No special preparation is usually required. Tell your clinician about your symptoms, possible allergen exposures, and any allergy medicines or biologic treatments you are using, and follow their instructions before testing.
Reference range
Adult: 10-40 U/LN/A
No special preparation required. Avoid fatty meals before the test if possible.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
A positive result means that IgE antibodies to one or more tree allergens were detected, indicating allergic sensitization. It does not by itself prove that the allergens cause your symptoms, so results should be interpreted with your medical history and, when appropriate, allergy testing. A negative or undetectable result makes sensitization less likely but does not completely exclude an allergy.
