呼吸道感染因感染解剖位置不同,在感染病原学、临床表现和疾病严重程度上,会有所区别。下呼吸道感染是常见病、多发病,但老年人感染临床特征往往不典型,常缺乏特异性症状和体征,甚至无呼吸系统症状,导致延误治疗或与其他疾病相混淆,因此有效、快速的预测感染的检验方法十分必要。近年,血清降钙素原(PCT)及超敏C-反应蛋白(HS-CRP)在预测细菌感染中的作用得到重视~[1],并在感染性疾病早期诊
Respiratory infections due to infection in different anatomical locations, in the etiology of infection, clinical manifestations and severity of the disease, there will be differences. Lower respiratory tract infections are common and frequently occurring, but the clinical features of elderly infections are often atypical and often lack specific symptoms and signs, or even no respiratory symptoms, leading to delays in treatment or confusion with other diseases, hence effective and rapid prediction Infection test method is necessary. In recent years, the role of serum procalcitonin (PCT) and high-sensitivity C-reactive protein (HS-CRP) in the prediction of bacterial infections has been highlighted [1], and in the early diagnosis of infectious diseases
