What is this test?

This test looks for IgG antibodies against a mixture of mold allergens in your blood. IgG antibodies are part of the immune response that can develop after exposure to mold.

Why might I need this test?

It may be used to help evaluate suspected mold exposure or sensitivity when symptoms include sneezing, congestion, wheezing, or skin irritation. It is generally considered alongside your symptoms, exposure history, and other allergy testing.

How is the test performed?

A blood sample is collected and analyzed in a laboratory for IgG binding to the mold allergens in the tested mixture. The result is reported as negative or positive.

How do I prepare for the test?

No special preparation is usually required. Tell your clinician about any medicines you take, recent mold exposure, allergies, and symptoms, and do not stop prescribed medicines unless instructed.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

A positive result indicates that IgG antibodies to at least one allergen in the tested mixture are present, suggesting prior exposure or sensitization. It does not establish that mold is causing your symptoms or that you have an IgE-mediated mold allergy. Results should be interpreted by a clinician in the context of your medical history, environment, and other testing.

Frequently asked questions

Does a positive result mean I am allergic to mold?
Not necessarily. A positive IgG result can show sensitization or prior exposure, while symptoms and other evidence are needed to determine whether you have a clinical mold allergy.
What symptoms can be related to mold exposure?
Possible symptoms include sneezing, nasal congestion, cough, wheezing, eye irritation, and skin irritation. These symptoms can also have causes unrelated to mold.
Should I remove mold from my home based on this result?
Discuss the result with your clinician or an allergist. Visible mold and areas of persistent dampness generally warrant appropriate cleanup and moisture control regardless of the blood test result.
