Abstract

We reported a modified CFW assay for rapid detection of fungi in blood samples and evaluated its efficacy in vivo and in vitro. The positive rate, sensitivity, and negative predictive values of the modified CFW method were all significantly higher than those of traditional fungal culture and KOH methods.

Keywords: Blood; Candida albicans; Candidemia; Modified calcofluor white stain.
