Avoid exposure of specimen to atmosphere to prevent sample contamination from environment. Aspergillus Galactomannan Index. The index is the optical density (OD) value of the specimen divided by the mean OD of wells containing the cutoff control serum (low-positive control). Expected performance in serum in different patient populations. University of Washington. Methodology. 0060273. Nonetheless, early diagnosis and initiation of an appropriate antimicrobial therapy may result in improved survival rates in these patients. * Component test codes cannot be used to order tests. Patients with invasive Aspergillus infections have a high mortality rate; therefore, early diagnosis is important. How is Aspergillus (Galactomannan) Antigen test performed?
