Clinical Info
A titer of 1:8 or greater suggests Aspergillus infection or allergy. Cross-reactions with dimorphic fungi are not unusual within 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.
