Rapid Diagnosis of IPA Relied on Calcofluor White Fluorescence Staining: Two Cases Report.

Invasive pulmonary aspergillosis (IPA) is a serious infectious disease with high mortality. However, the rapid diagnosis of IPA remains difficult since the microbiological evidence is difficult to obtain or time-consuming. Thus, we attempted to rapidly diagnose two pediatric cases with respiratory failure due to IPA via bronchoalveolar lavage fluid with Calcofluor White fluorescence staining, which has rarely been used before.
