Abstract

Positive Platelia Aspergillus test results were observed in consecutive serum samples from an immunocompromised host during amoxicillin-clavulanic acid treatment, and a correlation between plasmatic amoxicillin concentration and galactomannan optical density index was observed. Amoxicillin-clavulanic acid vials tested positive for galactomannan but were negative for Aspergillus DNA.
