Semi-quantitative Enzyme Immunoassay
This test is New York DOH approved.
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).
For bronchial specimens refer to Aspergillus Galactomannan Antigen by EIA, Bronchoscopy (ARUP test code 2003150)
