Abstract
Objective To compare the effectiveness of different methods of collecting nasopharyngeal secre-tions by nasopharynx swab and nasopharyngeal underpressure suction catheter for rapid detection of influenza virus. Methods Nasopharyngeal secretions as the experimental samples of 1042 patients with acute respiratory tract disea-ses were collected by nasopharynx swab and nasopharyngeal suction catheter, and gold immunochromatographic assay (GICA) kit was applied for the detection of influenza viruses. Results The use of the above two methods collecting nasopharyngeal secretions as samples for rapid detection of influenza virus would get the same results. The difference between the two methods had no statistical significance( P > 0.05 ). Conclnsions Nasopharynx swab is a reliable method for rapid detection of influenza virus, which is fast and convenient, compared with nasopharyngeal suction catheter. Key words: Nasopharynx swab; Nasopharyngeal underpressure suction catheter ; Gold immunochroma-tographic assay; Rapid detection; Influenza viruses
