Interpretive Data
Cross-reactions with dimorphic fungi are not unusual with the genus Aspergillus. A negative test does not exclude infection, especially in immunocompromised patients. Best use of the test is with paired sera taken three weeks apart to detect a rise in titer against a single antigen.  
Note
Negative fungal serology does not rule out the possibility of current infection.
