Why This Test Might Be Ordered

Your healthcare provider may recommend this test if you have symptoms like persistent cough, fever, or lung issues, or if you’ve had recent exposure to moldy environments. It’s also used in people with weakened immune systems or those with conditions like asthma or chronic lung disease.

What to Expect Before the Test

No special preparation is needed. You’ll provide a blood sample, usually drawn from your arm. The test is quick and typically done in a lab setting.

What the Results Mean

Positive results suggest the presence of antibodies, which may indicate past exposure to *Aspergillus*. However, antibodies alone don’t confirm an active infection. Further testing, like a fungal culture or imaging, may be needed for diagnosis.

Common Causes of Positive Results

Positive results can occur from environmental exposure to *Aspergillus*, allergic reactions, or past infections. Some people may have false positives due to cross-reactivity with other fungi.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

This screening test is a first step in identifying potential exposure or immune response to *Aspergillus*. It’s not definitive for active infection but can guide further medical evaluation if needed.
This test is a qualitative screening and does not provide a specific concentration of antibodies. It helps healthcare providers assess risk and consider additional diagnostic steps if symptoms or exposure history are present.
What does a positive result mean for my health?
A positive result means your body has detected antibodies to *Aspergillus*, which could suggest past exposure or an immune response. However, it doesn’t confirm an active infection. Your doctor may order additional tests to check for symptoms or active disease.
Can I get this test at home?
No, this test requires a blood sample collected in a clinical setting. You’ll need to visit a healthcare provider or lab for the procedure.
