What is this test?

This test measures allergen-specific IgE antibodies in your blood against a mixture of common molds. IgE is an immune-system protein that can develop in response to an allergen.

Why might I need this test?

Your clinician may order this test if you have wheezing, nasal congestion, sneezing, watery eyes, or other symptoms that seem related to exposure to damp areas or mold.

How is the test performed?

A blood sample is collected and analyzed in a laboratory using an allergen-specific immunoassay. The result is reported as a qualitative positive or negative finding.

How do I prepare for the test?

No special preparation is usually required. Tell your clinician about any medicines you take, especially antihistamines, because they may affect allergy testing; do not stop prescribed medicines unless instructed.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

Does a positive result mean I have mold allergy?
It indicates sensitization to at least one mold in the tested panel, but the result must be compared with your symptoms and exposure history to determine clinical relevance.
Can this test identify exactly which mold causes my symptoms?
Not by itself. A mix screen may show whether antibodies to the panel are present; your clinician may recommend testing individual molds or other allergy evaluations if needed.
What if the test is negative but I still have symptoms?
A negative result does not rule out every type of mold-related illness or allergy. Your clinician may consider other causes of your symptoms or additional testing.
