降钙素原在儿童社区获得性肺炎的临床应用

摘要

降钙素原（procalcitonin，PCT）是降钙素的前体物质，是近年来新发现的诊断细菌感染的指标。在儿童社区获得性肺炎中检测其血清浓度，可用于早期估计感染病原体的种类，评价感染的严重程度，指导用药及判断预后等。%Procalcitonin (PCT), a precursor of hormone calcitonin, is used as an indicator of bacterial infections in recent years. PCT plays an important role in early identiifcation of pathogens, evaluation of the severity of infection, medication guidance and prognosis judgment in children with community acquired pneumonia.
