Optimal Length for Nasal Mid-turbinate and Nasopharyngeal Swabs

April 8, 2021 updated by: Tobias Todsen, Rigshospitalet, Denmark

Optimal Insertion Length for Nasal Mid-turbinate and Nasopharyngeal Swabs for Respiratory Virus Infection Diagnostic Testing - a Clinical Trial

This study aim to explore the optimal swap insertion length for mid-turbinate and nasopharyngeal samples. Our clinical trial took place at a Covid-19 test center in Copenhagen. Participants consisted of voluntary citizens who were at the test center for a nasopharyngeal antigen quicktest. An endoscopic examination was performed simultaneous with the swap to measure the length from the vestibulum nasi to the posterior wall of the nasopharynx and the mid-turbinate.
