What This Test Measures

The test detects specific antibodies (immunoglobulins) produced by your immune system in response to *Aspergillus* exposure. These antibodies can appear after infection, allergic reaction, or exposure to mold spores.

Why It Might Be Ordered

Your healthcare provider may recommend this test if you have symptoms like persistent cough, wheezing, or lung problems, especially if you live in an area with high mold exposure or have a weakened immune system.

What to Expect Before the Test

No special preparation is needed. A blood sample will be drawn from a vein in your arm. You may feel a slight pinch, but it usually takes only a few minutes.

What the Results Mean

Positive results suggest possible exposure or infection, but further testing (like a confirmatory assay) may be needed. Negative results mean no detectable antibodies were found in this sample.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

What does a positive result mean?
A positive result indicates the presence of antibodies against *Aspergillus*, which may suggest past exposure, infection, or an allergic reaction. However, it does not confirm the current health status of your lungs or mold sensitivity. Follow-up testing may be needed to clarify diagnosis.
Can this test detect active infection?
This test primarily detects antibodies, which appear after exposure but may not always indicate an active infection. Active infection is often diagnosed with additional tests, such as imaging or cultures.
Is this test covered by insurance?
Coverage depends on your insurance plan and clinical indication. Check with your provider or insurance company to confirm if this test is approved for your specific situation.
