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.
No compliance statements are in use for this test.
