[Research progress of presepsin in sepsis diagnosis]

Sepsis is a frequently met syndrome with complex clinical symptoms and high mortality in emergency department. Early diagnosis of sepsis and timely treatment can improve survival. In recent years, the application of biomarkers [such as procalcitonin (PCT), C-reactive protein (CRP), interleukin-6 (IL-6)] are commonly used in the early diagnosis of sepsis, but their specificity and sensitivity are limited because of the long lag of report time. Soluble leukocyte differentiation antigen 14 sub type (sCD14-ST, namely presepsin) is a kind of novel biomarkers. Presepsin has a high specificity and sensitivity in the diagnosis of sepsis. It has some value to evaluate the severity of sepsis, antibiotic treatment of antibiotics, and prognosis of the patients with sepsis, and its latest detection method is fast and accurate, so it has the feasibility of clinical application.
