Turnaround time of diagnosis
The blood samples were obtained and transferred to ddPCR laboratory in about 10 min. Plasma was immediately isolated after centrifugation for 20 min. DNA extraction and PCR amplification were completed within 3 h. Data analysis was done within 30 min using GenePMS software. The average turnaround time of ddPCR was 4.2 ± 0.51 h, which was remarkably shorter than that of the blood culture test (90.6 ± 10.9 h, P < 0.01).
