目的为了解重症监护病房（ICU）患者的感染状况，对208例患者的降钙素原（PCT）检测结果进行了分析。方法用荧光免疫方法测定了208例ICU患者的PCT结果并进行分析。结果208例患者PCT结果都有不同程度的升高、增高比率大于95%。结论降钙素元（PCT）是细菌感染的早期辅助诊断指标，降钙素原定量测定与其他实验室检查结果和临床评估一起用于协助评估ICU病房的重症患者发展为重症败血症以及败血症性休克的可能性。%Objective Learning the patient's infection in ICU, then choose 208 cases to analyze their detection numerical of PCT.Methods Use Fluorescence Immunoassay to detect the 208patients's PCT numerical.Results Among the 208 cases, there are obvious rising of their PCT numerical on diverse degree, and average increasing rate is above 95%.Conclusion PCT is a auxiliary indicator for early diagnosis of Bacterial Infection, PCT quantitative determination、tests results in laboratory and clinical evaluation are three methods to assist assess the severe cases in ICU, who may turn to Severe Sepsis or Sepsis Shock.
