Aid in the diagnosis of invasive/disseminated aspergillosis.
Semi-quantitative Enzyme Immunoassay
Plain red or serum separator tube.
Separate serum from cells within 2 hours of collection. Transfer 2 mL serum to a sterile ARUP Standard Transport Tube (ARUP Supply #43115). Available online through eSupply using ARUP Connect™ or contact Client Services at (800) 522-2787. (Min: 1 mL)
Plasma. Hemolyzed specimens.
After separation from cells: Ambient: Unacceptable; Refrigerated: 1 week; Frozen: 1 week

Negative results do not exclude the diagnosis of invasive aspergillosis. A single positive test result (index equal to or greater than 0.5) should be clinically correlated by testing a separate serum specimen because many agents (e.g. foods, antibiotics) may cross-react with the test. If invasive aspergillosis is suspected in high-risk patients, serial sampling is recommended.
The false-positive rate is higher in children than in adults. (Cancer 91:311, 2001; J.Clin Oncol 20:1898,2002; Mycosis 41:373,1998).
No compliance statements are in use for this test.
For bronchial specimens refer to Aspergillus Galactomannan Antigen by EIA, Bronchoscopy (ARUP test code 2003150). For sputum or tissue specimens, refer to Aspergillus Species by PCR (ARUP test code 3000265).
