Detection of SARS-CoV-2 in Nasal Swabs: comparison with Nasopharyngeal Swabs

Comparison of nasal and nasopharyngeal swabs for influenza detection in adults.

OBJECTIVE Examine differences in the detection of influenza by specimen and test type using paired nasal and nasopharyngeal swabs. DESIGN Prospective study SETTING Enrollment took place between January and March 2007 in a central Wisconsin population. PARTICIPANTS Adult patients were screened and enrolled by trained research coordinators following medical encounters for acute respiratory ...

Comparison of patient-collected and lab technician-collected nasopharyngeal and oropharyngeal swabs for detection of COVID-19 by RT-PCR

Background & Objective:  A simple approach to prevent close contact in healthcare settings during the COVID-19 outbreak is to train patients to collect their own nasopharyngeal and oropharyngeal swabs and deliver them to medical laboratories to have them processed. The aim of our study was to c...

Diagnostic sensitivity of nasopharyngeal and nasal swabs for the molecular detection of EHV-1.

Recovery of Bordetella pertussis from nasopharyngeal swabs.

Comparing the Yield of Nasopharyngeal Swabs, Nasal Aspirates, and Induced Sputum for Detection of Bordetella pertussis in Hospitalized Infants

BACKGROUND  Advances in molecular laboratory techniques are changing the landscape of Bordetella pertussis illness diagnosis. Polymerase chain reaction (PCR) assays have greatly improved the sensitivity detection and the turnaround time to diagnosis compared to culture. Moreover, different respiratory specimens, such as flocked nasopharyngeal swabs (NPSs), nasopharyngeal aspirates (NPAs), and i...
