Aspergillus Antigen EIA
Platelia™ Aspergillus EIA immunoenzymatic sandwich microplate assay, cleared by the FDA for the detection of galactomannan in serum or BALF.
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.
- Certain gluconate containing fluids (Vetivex pHLyte NOT Plasmalyte or Norm-R)
- Potentially penicillin antibiotics
- High: Alternaria, Fusarium, Geotrichum, Paecilomyces
- Low: Coccidioides, Cryptococcus, Blastomyces, Histoplasma
