Abstract
It is well known that cross reactions with other fungal pathogens including Histoplasma capsulatum can occur with the use of the Platelia™ Aspergillus galactomannan assay. We report two patients with confirmed blastomycosis whose bronchoalveolar lavage (BAL) fluid tested positive for Aspergillus galactomannan despite no evidence of aspergillosis.
