Abstract：
OBJECTIVE: Proper diagnosis of invasive aspergillosis is challenging because conventional methods lack sensitivity and are complicated by time-consuming incubation processes. To meet the requirement for early diagnosis the new Aspergillus-specific point-of-care test LFA-IMMY™ was evaluated with respect to the ability to accurately detect Aspergillus in bronchoalveolar fluids and sputa, and to clarify the potential of cross-reactivity with other fungal pathogens.
METHODS: Respiratory specimens (n = 398) from non-selected patients (n = 390) underwent either fungal microscopy, culture or both before Aspergillus lateral flow assay (LFA-IMMY) testing.
RESULTS: For Aspergillus culture- and microscopy-positive samples, sensitivity (48/52) and specificity (44/48) were 92% (95% CI 8.0%-9.7%) and 91% (95% CI 7.9%-9.7%), respectively; cross-reactivity was documented with non-Aspergillus pathogens.
CONCLUSIONS: LFA-IMMY is a reliable diagnostic tool for the detection of Aspergillus in respiratory samples.
