Rejection Criteria:
Body fluid.
Turn Around Time:
2-4 days upon receipt at reference laboratory

In general, immunodiffusion measures IgG and a positive result may suggest past infection. The test is positive in about 90% of sera from patients with aspergilloma and 50-70% of patients with allergic bronchopulmonary aspergillosis. A negative test (none detected) does not exclude aspergillosis.
Comments:
This test uses culture filtrates of Aspergillus fumigatus, Aspergillus flavus, Aspergillus niger, and Aspergillus terreus.
Methodology:
Qualitative Immunodiffusion
