What is this test?

This test measures IgE antibodies directed against a mixture of mold allergens. It is a screening blood test for sensitization to common mold allergens and does not identify a specific mold with certainty.

Why might I need this test?

It may be ordered if you have wheezing, cough, nasal congestion, sneezing, eye irritation, or other symptoms that appear after exposure to damp areas, moldy buildings, or outdoor mold spores. The result can help guide allergy evaluation and treatment.

How is the test performed?

A blood sample is collected and tested in a laboratory for allergen-specific IgE. The result is reported as positive, negative, or sometimes equivocal, depending on the laboratory's testing method and interpretation.

How do I prepare for the test?

No special preparation is usually required. Tell your clinician if you are taking antihistamines or other medicines, because these may affect allergy testing and symptoms; do not stop prescribed medication without advice.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

Does a positive result mean I have mold toxicity?
No. A positive result shows sensitization to tested mold allergens, not “mold toxicity” or systemic poisoning from mold. The result should be interpreted alongside your symptoms and medical history.
Can this test tell me exactly which mold caused my symptoms?
Not by itself. The test uses a mixture of mold allergens, and another test may be needed to identify a specific mold or confirm clinical relevance.
Should I avoid mold if the test is positive?
Discuss exposure reduction and treatment options with your clinician or allergist. Limiting indoor mold and managing allergy symptoms are generally important, but the test result alone does not determine a specific action plan.
