Interpretation of the concentrations of procalcitonin during infectious and inflammatory processes

The paper analyzes the most important clinical studies dealing with the measurement of procalcitonin concentrations in patients with lower respiratory tract infections or sepsis. Procalcitonin is a marker of bacterial infection, which is successfully used for diagnosis and antimicrobial therapy monitoring in patients with pneumonia or in septic states. The review presents the latest algorithms for interpreting the concentrations of procalcitonin in clinical practice.
