摘要
目的:比较两种不同方法检测急性下呼吸道感染患儿病原情况。方法:回顾性分析163例下呼吸道感染患儿进行呼吸道直接免疫荧光、血清IgM测定及痰培养检测呼吸道常见病原。结果:以直接免疫荧光抗体法结果为依据,在研究周期内,病毒病原总共46例(28.22%),以呼吸道合胞病毒为主29例(17.79%),两种不同病原检测方法结果差异显著。结论:单用血清IgM阳性诊断呼吸道病毒感染不合适。
Objective：To compare 2 methods for detecting pathogens of acute lower respiratory tract infection（ALRI） in children.Methods： The results of detecting common respiratory pathogens by respiratory direct immunofluorescence,serum IgM,sputum culture of 163 ALRI cases were retrospectively analyzed.Results：Based on the results of direct immunofluorescence,46（28.22%） cases of virus pathogen and 29（17.79%） cases of predominant respiratory syncytial virus were found in the research period.The difference between the 2 methods is significant.Conclusion： Using Serum IgM alone is not appropriate for diagnosing respiratory virus infection.
