Duration of microbial cell-free DNA (mcfDNA) positivity compared with blood culture for Staphylococcus aureus and GN bacteremia. A, Kaplan-Meier curve showing duration of positivity for KT vs BC for all bloodstream infections. The median duration of positivity was significantly different in mcfDNA at 15 days vs BC at 2 days (P < .0001 by log-rank test). B, Kaplan-Meier curve showing duration of positivity for KT and BC for S.a., the median duration of positivity was significantly different in mcfDNA at 15 days vs BC at 3 days (P < .0001 by log-rank test). For GN infections, the median duration of positivity was significantly different in mcfDNA at 8 days vs BC at 0 day (P < .0001 by log-rank test). Abbreviations: BC, blood culture; GN, gram-negative; KT, Karius test; S.a., Staphylococcus aureus.
