Comparing different methods for testing respiratory viruses

A Comparative Evaluation of Specimen Adequacy of a Traditional Nasopharyngeal Swab as Compared to Nasopharyngeal Saline Wash, Saliva, and Serum to Test for Respiratory Viruses and Antibody Response

NA · University of Nebraska · NCT05864118

This study is testing if new ways to collect samples, like using saliva or a gentle wash, can diagnose respiratory infections just as well as the traditional nose swab, while being easier and more comfortable for patients.

What this trial studies

This study evaluates the effectiveness of two novel specimen collection methods—nasopharyngeal saline wash and saliva collection—against the traditional nasopharyngeal swab for diagnosing respiratory tract infections (RTIs). Given the invasive nature of nasopharyngeal swabbing, which can cause discomfort and lead to inadequate specimen procurement, the study aims to determine if the new methods can provide a less traumatic alternative for patients. Participants aged 19 and older presenting to the emergency department with a nasopharyngeal swab ordered will be included in the study. The outcomes will focus on the accuracy and patient experience associated with each collection method.

Who should consider this trial

Good fit: Ideal candidates are adults aged 19 years or older who are presenting to the emergency department with a nasopharyngeal swab ordered.

Not a fit: Patients who do not require testing for respiratory viruses or those under 19 years of age may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to less invasive and more patient-friendly methods for diagnosing respiratory infections.

How similar studies have performed: While the traditional nasopharyngeal swab method is well-established, the novel collection methods being tested are relatively new and have not been widely validated in previous studies.
