The result is not intended to be used as the sole means for clinical diagnosis or patient management decisions.
- – Antifungal therapy may cause false negative results in patients with aspergillosis.
- – Low positive results (0.5-1.5 GMI) are equivocal and may represent false positives, as the cutoff of 0.5 GMI was determined based on human studies for the early diagnosis of invasive fungal infections.
- – False positives can be caused by:
> Piperacillin-tazobactam, amoxicillin/clavulanic acid
> PLASMA-LYTE and other fluids containing sodium gluconate
> Infection with Penicillium, Alternaria, Paecilomyces, Fusarium, Histoplasma and Blastomyces, or airway colonization with above organisms
