Duration of microbial cell-free DNA positivity in patients with metastatic infection. Kaplan-Meier curves showing duration of positivity for KT and BC in patients with metastatic vs nonmetastatic infection. BC metastatic median duration of positivity was 4 days. BC nonmetastatic median duration of positivity was 0 days. KT metastatic duration of positivity was 22 days. KT nonmetastatic duration of positivity was 8 days. P = .0054 by log-rank (Mantel-Cox) test. Abbreviations: BC, blood culture; KT, Karius test; Met, metastatic; Non, nonmetastatic.
