Abstract
Surveillance by clinical epidemiology teams for invasive fungal infections (IFIs) in healthcare settings can be challenging due to several factors including low sensitivity of noninvasive conventional microbiologic diagnostics, nonspecific clinical presentation, and complex patient populations. Recently, availability of microbial cell-free DNA testing (cfDNA) via the Karius Test has shown promise for increased diagnostic sensitivity of IFIs. However, how to best incorporate cfDNA results into IFI surveillance remains a vexing challenge. Herein, we provide perspectives on the benefits and challenges of use of cfDNA for IFI surveillance.
