What is this test?

This blood test measures allergen-specific IgE antibodies against a panel of six common inhalant allergens, such as pollens, dust mites, or animal allergens. The results are reported for each allergen included in the mix.

Why might I need this test?

A clinician may order this test to evaluate suspected environmental allergies, especially when symptoms such as sneezing, nasal congestion, wheezing, or itchy eyes occur after exposure to airborne substances. It can help guide further allergy evaluation and treatment.

How is the test performed?

A blood sample is drawn and tested in a laboratory for IgE antibodies to the individual allergens in the panel. Results are interpreted alongside your symptoms, exposure history, and other allergy assessments.

How do I prepare for the test?

No special preparation or fasting is usually required for this blood test. Tell your clinician about current medications, recent allergen exposures, and any changes in your allergy symptoms.

Reference range

Adult: 10-40 U/LN/A

Frequently asked questions

Does a positive result mean I am allergic to that substance?
It indicates that your immune system has produced IgE antibodies to the substance, which is consistent with sensitization. Your clinician will consider whether your symptoms and exposure history match the result.
Can this test determine the severity of my allergy?
No. The antibody result helps identify sensitization but does not directly measure symptom severity. Your clinician may also consider testing methods such as skin-prick testing.
Why does the report list several different allergens?
The test includes a group of common inhalant allergens and provides a separate result for each one. This helps determine which specific allergens may be relevant to your symptoms.
