Procalcitonin (PCT) is used as a biomarker for the diagnosis of sepsis, severe sepsis and septic shock. At the same time, PCT has also been used to guide antibiotic therapy. ⋯ Using serially monitored PCT levels, the duration and need of antibiotic therapy can be better adapted to the individual requirements of the patient.
