Nasal Swab Home Collection Kit (NSHC Kit) Study

Influenza Viral Infections

The purpose of this study is to demonstrate that persons over the age of 13 years can obtain a self-collected nasal swab reliably and safely for subsequent use in the diagnosis of influenza. Similarly, the purpose is to demonstrate that parents or guardians can safely and effectively collect nasal swab specimens from children, ages 0 through 12 years, and others needing assistance in doing so, and that these parent/guardian-collected nasal swabs can also be used in the diagnosis of influenza. Clinical performance of the swabs will be based on the comparison of the performance of the nasal swab that is self- or parent/guardian-collected to one collected from the same specimen donor by a skilled clinical coordinator and used in CLIA (Clinical Laboratory Improvement Amendments)-waived, rapid diagnostic test called Sofia Influenza A+B FIA (fluorescence immunoassay analyzer).
