Abstract Background Molecular diagnostics may enable early, noninvasive detection of invasive fungal disease (IFD) in immunocompromised patients. Cell‐free deoxyribonucleic acid (cfDNA) fungal polymerase chain reaction (PCR) assays were recently incorporated into institutional prolonged febrile neutropenia pathways. We aimed to evaluate the performance of plasma cfDNA PCR panels (mold and Candida panels) in pediatric oncology and hematopoietic stem cell transplant (HSCT) patients with clinical concern for IFD. Methods This single‐center, observational study assessed plasma cfDNA fungal PCR performance for noninvasive IFD detection in hospitalized pediatric oncology and HSCT patients. The primary outcome was IFD diagnosis per published consensus definitions within 1 month. Positive and negative agreement between plasma cfDNA fungal PCR and consensus definitions were calculated. We also described test turnaround time and patient survival. Results From October 2021 to 2022, 54 patients underwent 60 evaluations with 11 proven/probable IFD cases. Comparing plasma cfDNA fungal PCRs to consensus definitions for proven/probable IFD, there was 73% positive agreement and 96% negative agreement. Two proven/probable cases with negative PCRs were caused by organisms not included on either panel. Median time to cfDNA fungal PCR result was 35 hours (interquartile range: 19–69) in eight proven/probable cases detected by cfDNA fungal PCR. There were 17 deaths among 54 patients, and IFD contributed to 45% of deaths in patients with proven/probable IFD. Conclusions Plasma cfDNA fungal PCRs detected relevant molds or yeast in most cases classified as proven/probable IFD. However, this targeted approach missed some cases. More studies are required to determine optimal utilization of molecular diagnostics in pediatric patients.
