Table 2 Differences in serum PCT values according to final diagnosis (confirmed vs. not confirmed) and etiology (coagulase-negative staphylococci vs. other pathogens) of sepsis
Study group | Serum PCT values, ng/mL median (25th–75th interquartile range) | ||
|---|---|---|---|
Onset of symptoms | 12–24 h | 36–48 h | |
Not confirmed sepsis, n = 39 | 0.34 (0.24–0.58) | 0.44 (0.25–1.20) | 0.47 (0.33–0.92) |
Confirmed sepsis, n = 61 | 2.46 (0.68–23.20) | 12.65 (1.01–49.00) | 5.15 (0.99–16.23) |
P value* | < 0.0001 | < 0.0001 | < 0.0001 |
Sepsis caused by CoNS, n = 22 | 0.76 (0.42–7.70) | 1.48 (0.56–16.44) | 0.88 (0.51–2.27) |
Sepsis caused by other pathogens, n = 39 | 7.60 (1.01–27.01) | 20.85 (6.54–63.50) | 8.62 (4.32–32.0) |
P value* | < 0.049 | < 0.003 | < 0.0003 |
