Summary

Aspergillosis is the name for a group of conditions caused by Aspergillus mould.

Usage

Culture

Isolation of Aspergillus for identification and sensitivities (if required.)

Aspergillus Antibody (precipitins)

Detection of antibodies to Aspergillus spp. Appropriate for the diagnosis of aspergillosis in immunocompetent patients e.g. allergic bronchopulmonary aspergillosis (ABPA), aspergilloma, chronic necrotising aspergillosis, aspergillus sinusitis

 Aspergillus antigen

This test detects the presence of the Aspergillus antigen galactomannan in serum or BAL fluid to diagnosis invasive aspergillosis in immunocompromised patients.

Aspergillus PCR

Detects presence of Aspergillus DNA in whole blood or BAL fluid. Generally used serially to detect rising levels post-bone marrow transplant.
