    Clinical Significance+-

    The Aspergillus Antigen EIA test aids in the diagnosis of systemic aspergillosis in animals. This test has low sensitivity in dogs with sino-nasal aspergillosis; therefore, the test is not recommended for screening in those cases.

    Methodology+-

    Platelia™ Aspergillus EIA immunoenzymatic sandwich microplate assay, cleared by the FDA for the detection of galactomannan in serum or BALF.

    Limitations+-

    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.
    Cross Reactivity/False Positive:
    • Certain gluconate containing fluids (Vetivex pHLyte NOT Plasmalyte or Norm-R)
    • Potentially penicillin antibiotics
    • High: Alternaria, Fusarium, Geotrichum, Paecilomyces
    • Low: Coccidioides, Cryptococcus, Blastomyces, Histoplasma
