Abstract:
Objective To explore the clinical application value of rapid detection method for respiratory tract influenza virus and mycoplasma pneumonia(MP).Methods 386 cases were selected from patients with respiratory infections in our hospital from Janu-ary 2011 to December 2015 in the study,nasopharyngeal secretions A,B influenza virus were detected by gold immunchromato-graphic assay,the Mycoplasma pneumoniae(MP)was detected by rapid culture,and pathogens-IgM were detected by immunofluo-rescence assay.In the end,the two rapid detection detection method were compared with immunofluorescence assay.Results 386 cases of respiratory tract infections patients were detected by immunofluorescence assay,54 cases were found influenza A virus in-fection,the positive rate was 13.59%,37 cases were found influenza B virus infection,the positive rate was 9.59%,61 cases were found MP infection,the positive rate was 15.80%.In detections of influenza A virus infection and influenza B virus infection,im-munchromatographic assay sensitivity were 20.37%,18.92% and specificity were 93.41%,92.77%.In detection of MP infection, rapid culture sensitivity was 37.70% and specificity was 89.85%.Conclusion Rapid detection of respiratory influenza virus,MP infection sensitivity is low,only as a supplementary means of indirect immunofluorescence assay clinically.
