  • Test Code


  • 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.
    • – 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
