Overview
Laboratory findings consistent with the diagnosis of aspergillosis include positive aspergillus antibody test, positive galactomannan test, and elevated concentration of IgE immunoglobulin.[1][2][3]
Laboratory Findings
Complete Blood Count
- Eosinophilia
Electrophoresis
- Elevated concentration of serum immunoglobulin E (IgE)
Biomarkers
- Positive galactomannan assay
- Positive beta-D-glucan assay
Culture
- Positive sputum culture and stain following bronchoalveolar lavage (BAL)
- Can be done on a variety of sterile specimens and Aspergillus spp. present as rapidly growing molds that are visible 1-3 days after incubation.
- However, patients with invasive aspergillosis may have negative cultures.
