The oropharyngeal swab is a sampling tool used to extract mucosal cells and secretions from the oropharynx. The sampling method is to use sterile throat swabs and other items to penetrate deep into the pharynx, go through the root of the tongue to the posterior pharynx, tonsil crypts, sidewalls, etc., wipe left and right repeatedly for 3 to 5 times, and gently take out the swab. Then put the swab stained with mucosal cells and secretions into the virus sampling tube and send it for inspection in time.
