Comparison between white blood cell count, procalcitonin and C reactive protein as diagnostic and prognostic biomarkers of infection or sepsis in patients presenting to emergency department

Abstract

Our data demonstrate that WBC, but more CRP and PCT are reliable diagnostic and prognostic biomarkers, when considered in combination and with severity clinical score. PCT confirms its stronger usefulness as a diagnostic marker of sepsis. A multi-diagnostic tools approach is fundamental to perform a correct and rapid diagnosis of infection and sepsis in ED.
