What is this test?

This test measures allergen-specific IgE antibodies in your blood. IgE is an immune-system protein that can form in response to particular allergens, such as pollens, molds, foods, or insect products.

Why might I need this test?

Your clinician may order this test to evaluate a suspected allergy, identify which allergens may trigger your symptoms, or help guide allergy testing and treatment. It may be considered when symptoms suggest exposure to a specific allergen or allergen group.

How is the test performed?

A blood sample is collected and analyzed in a laboratory for IgE antibodies against the allergens contained in Mix 71. The report may show the amount of each allergen-specific IgE detected, along with the laboratory's interpretation.

How do I prepare for the test?

This test usually does not require fasting or special preparation. Tell your clinician about any allergy medicines or biologic treatments you are using, because they may affect the results, and do not stop prescribed medication without medical advice.

Frequently asked questions

Does a positive result mean I am definitely allergic?
No. It indicates immune sensitization to an allergen in the mix, but the result must be compared with your symptoms and medical history to determine whether there is a clinically relevant allergy.
Can I take allergy medicine before this test?
Some medicines can affect allergen-specific IgE results. Ask your clinician whether to continue or adjust any medicines before testing, and never stop prescribed treatment without guidance.
Why might the test not match my symptoms?
The result may reflect sensitization rather than an active allergy, and your symptoms could be caused by another condition or allergen. Your clinician can interpret the result alongside your history and other allergy tests.
