Differential diagnosis of bacterial from candidal bloodstream infections in ICU patients: the role of procalcitonin

Early differentiation of bacterial from candidal bloodstream infections (BSIs) in the presence of sepsis or septic shock is crucial because of the need for appropriate treatment initiation. Clinical data, although limited, suggest a role for procalcitonin (PCT) [1-3]. The aim of this study was to investigate a possible association between the etiology of BSIs and the serum PCT levels.
