Performance of plasma calprotectin as a biomarker of early sepsis: a pilot study.

Aim: To determine the performance of plasma calprotectin as a marker of sepsis on intensive care unit (ICU) admission and as a marker of mortality day 30 post-ICU admission.

Materials & Methods: Consecutive ICU patients were allocated to: sepsis (n = 15), postoperative inflammation (n = 23) and intoxication without inflammation (n = 7) groups.
