据流行病学统计每年>14岁的社区获得性肺炎(CAP)患者约占居民总数的8.3‰,1/4的患者需要住院,病死率约为2.7%~([1])。成人CAP的主要致病菌仍为肺炎链球菌,由于该病原菌传统实验室诊断方法敏感度差,导致一部分CAP的初始治疗抗生素选择失败,不但延误了病情还增加了医疗资源的浪费和患者的经济负担~([2])。尿抗原检测肺炎链球菌是一种体外快速免疫层析(ICT)试验,为肺炎链球菌肺 According to the epidemiological statistics, community-acquired pneumonia (CAP) patients aged> 14 years each account for about 8.3% of the total number of residents, and one-fourth of patients require hospitalization with a mortality rate of about 2.7% ([1]). The main pathogens in adult CAP are still Streptococcus pneumoniae. Due to the poor sensitivity of the traditional laboratory diagnostic methods of this pathogen, the initial selection of antibiotics for CAP failed, which not only delayed the disease but also increased the waste of medical resources and the economy of the patients Burden ~ ([2]). Urinary Antigen Detection Streptococcus pneumoniae is an in vitro rapid immunochromatographic (ICT) assay for Streptococcus pneumoniae lung
