Clinical Trial Summary

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.
