Serum separator tube.
Separate serum from cells ASAP or within 2 hours of collection. Transfer 0.5 mL serum an ARUP Standard Transport Tube. (Min: 0.15 mL)
After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)
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.
This test uses culture filtrates of Aspergillus fumigatus, Aspergillus flavus, Aspergillus niger, and Aspergillus terreus.
