Title: Pilot study of participant-collected nasal swabs for acute respiratory infections in a low-income, urban population Document date: 2016_1_6
ID: 66r1k03d_10
Snippet: Participant-collected nasal swabs for acute respiratory infections virus and parainfluenza. The research swab was positive only for respiratory syncytial virus. Overall sensitivity for the self-swab to capture any respiratory pathogen was 83.3% (95% confidence interval [CI] 64%-102%), and 87.5% (95% CI 63%-112%) for influenza cases. Specificity was 100%, and negative and positive predictive values were 78.6% and 100%, respectively. Sensitivity to.....
Document: Participant-collected nasal swabs for acute respiratory infections virus and parainfluenza. The research swab was positive only for respiratory syncytial virus. Overall sensitivity for the self-swab to capture any respiratory pathogen was 83.3% (95% confidence interval [CI] 64%-102%), and 87.5% (95% CI 63%-112%) for influenza cases. Specificity was 100%, and negative and positive predictive values were 78.6% and 100%, respectively. Sensitivity to capture respiratory pathogens for a person taking their own swab was 71.4% (95% CI 32%-111%), and for a parent taking a swab of a child, was 90.9% (95% CI 73%-109%); sensitivity for influenza was 100% for someone taking their own self-swab, and 75.0% (95% CI 63%-112%) for a parent taking the swab.
