What is this test?
The Aspergillus antibody test detects whether your immune system has produced specific antibodies (IgG, IgM) against Aspergillus fungi. Aspergillus is a common mold found in soil, plants, and decaying material. Most people inhale these fungi daily without harm, but individuals with weakened immune systems or underlying lung conditions may develop an infection called aspergillosis.
How is the test performed?
A healthcare professional will draw a blood sample from a vein in your arm. The sample is sent to a laboratory where it is analyzed using immunoassay techniques to detect the presence and levels of Aspergillus-specific antibodies.
Do I need to prepare for the test?
No special preparation is needed. You do not need to fast before this test. Inform your doctor about any medications or supplements you are taking, as they may affect test results.
What do the results mean?
Results are typically reported as positive or negative: • Positive: Antibodies detected - may indicate current infection, past exposure, or allergic reaction to Aspergillus • Negative: No antibodies detected - suggests no current infection, but does not completely rule out aspergillosis, especially in early stages or severely immunocompromised patients Your doctor will interpret results alongside your symptoms, imaging studies (like chest X-ray or CT), and other laboratory tests.
Reference range
Negative: < 1:4 (No significant antibody titer detected). Equivocal: 1:4-1:8 (Borderline antibody level, recommend repeat testing). Positive: > 1:8 (Significant antibody titer indicating exposure or infection)N/A
No special preparation required. Patient may eat and drink normally before specimen collection. Inform the laboratory of any recent antifungal therapy as it may affect results.
