Optimal Length for Nasal Mid-turbinate and Nasopharyngeal Swabs

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.

    Time frame: From inclusion at the testcenter until the COVID-19 testing was completed.

    Endoscopic measurement of the length from the vestibulum nasi to the posterior wall of the nasopharynx.

  2. Length from the vestibulum nasi to the mid-turbinate.

    Time frame: From inclusion at the testcenter until the endoscopic examination was completed
