Asper A: Negative Index: By report |
| Interpretive Data: | |
|
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. food, antibiotics) may cross-react with the assay. If invasive aspergillosis is suspected in high-risk patients, serial sampling is recommended. The false positive rate is higher in children than in adults.
