The patient had no other signs of infection despite extensive testing (CT scans, sputum, PCR), raising suspisions that something was wrong with this diagnosis. The only food item being consumed by the patients at this time were frozen fruit flavoured water in the form of ice-pops. On testing it was found that these drinks contained significant amounts of fungal growth (Penicillin) and as the amounts detected declined soon after it was assumed that this was the source of a false positive galactomannan test result and the drinks were stopped.
The authors caution fellow doctors that other foodstuffs could potentially cause false positives as they also contain types of galactomannans. These can include the types of food given to similar patients as cooling drinks, ice cream etc.
In this case unnecessary antifungal medication was administered which can complicate treatment and cause severe side effects so it would have been better to avoid giving it.
