Plasma Microbial Cell-free DNA Metagenomic Sequencing for Diagnosis of Invasive Fungal Diseases Among High-risk Outpatient and Inpatient Immunocompromised Hosts

A positive result by mcfDNA sequencing may reduce the need for invasive sampling in patients with suspected IFD. In this exploratory analysis, its high sensitivity and specificity for invasive mucormycosis suggests it could be useful for early treatment and intervention of this IFD. Future studies should focus on understanding how specific factors impact the sensitivity of mcfDNA sequencing for invasive aspergillosis.
