The invention relates to a respiratory tract adenovirus IgA antibody detection test paper strip, which comprises a sample pad, a marker pad, a nitrocellulose membrane, water absorption paper and a back plate, and is characterized in that the nitrocellulose membrane comprises a detection line coated with a respiratory tract adenovirus hexon protein antigen polypeptide and a control line coated with human IgA antibody. According to the present invention, the saliva sample is collected with a sterile degreasing cotton, and then is extruded with a syringe, and the IgA antibody in the saliva is detected through the respiratory tract adenovirus IgA antibody rapid chromatography paper strip so as to achieve the purpose of rapid diagnosis of the patient infecting the respiratory tract adenovirus. According to the present invention, the operation of the method is simple, the result is rapidly obtained, the method is suitable for the rapid diagnosis of the adenovirus infection in the respiratory tract in all levels of medical institutions, the sample collection is invasive, the discomfort of the traditional blood collection and the nasopharyngeal swab collection on the patient is avoided, the working efficiency of the health care workers is improved, and the clinical popularization rate of the diagnosis of the respiratory tract adenovirus is improved.
