In addition to the symptoms, an x-ray or computerized tomography (CT) scan of the infected area provides clues for making the diagnosis. Whenever possible, a doctor sends a sample of infected material to a laboratory to confirm identification of the fungus.
The following lab tests may be done
- Aspergillus antibody test
- Positive galactomannan test (a molecule from the fungus that is sometimes found in the blood)
- Immunoglobulin E (IgE) blood level
- Sputum stain and culture for Aspergillus
- Tissue biopsy
