What is this test?

This blood test measures allergen-specific IgE antibodies against a mixture of common mold allergens. IgE is an immune-system protein that can develop when a person reacts to a particular allergen.

Why might I need this test?

This test may be used to help evaluate symptoms suggestive of mold allergy, such as sneezing, nasal congestion, wheezing, or skin symptoms. Your clinician will interpret it alongside your exposure history and symptoms.

How is the test performed?

A blood sample is collected and analyzed in the laboratory for IgE antibodies to the mold allergens included in the test mix. The result is reported as detectable or not detectable.

How do I prepare for the test?

No special preparation is usually required for this blood test. Antihistamines and other allergy medicines may affect some allergy testing methods, so tell your clinician about any medicines or supplements you are taking.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Detectable mold-specific IgE suggests immune sensitization to one or more mold allergens in the panel. It may support an allergy diagnosis when it matches your symptoms and exposure history, but a positive result alone does not prove that mold is causing your symptoms. A not-detectable result makes mold allergy less likely, although it does not exclude every possible mold allergy.

Frequently asked questions

Does a positive result mean I have mold allergy?
It indicates that your immune system has developed IgE antibodies to at least one mold allergen in the panel. Your clinician should interpret the result with your symptoms and medical history.
What symptoms can mold allergy cause?
Possible symptoms include sneezing, runny or congested nose, itchy or watery eyes, cough, wheezing, or skin irritation. Symptoms vary, and mold exposure can also cause nonallergic irritation.
Can I have a mold allergy with a negative result?
Yes. The test does not include every mold, and some reactions may be caused by irritation rather than IgE-mediated allergy. Your clinician may recommend additional testing if the result does not fit your symptoms.
