AbstractSepsis is a common and serious complication in intensive care unit patients. An important factor in optimizing survival rates in septic patients is the ability to start treatment early in the course of disease; there is, therefore, a need for accurate diagnostic tests. In recent years, there has been a move away from the rather vague and nonspecific signs that were previously used to diagnose sepsis towards the possible adjunctive role of biomarkers. Many biomarkers have been proposed and assessed clinically, but none alone is specific enough to definitively determine diagnosis. The future direction of research is most likely a greater focus on the use of panels or combinations of markers with clinical signs. Some biomarkers may also be useful for prognosis and guiding therapy. Here, the authors will review our changing approaches to sepsis diagnosis and discuss some of the markers that seem most relevant at the present time.
