This action is not available.
Specimen collections from a patient’s anterior nasal cavity and nasopharynx are used to test for multiple viral illnesses such as influenza and COVID-19. Nasal swabs can be performed by the nurse or the patient with proper education. It is vital to understand the anatomy of these areas to obtain an accurate sample so that patients receive the appropriate care they need. See Figure \(\PageIndex{1}\) [1] for an image of the anatomy of the head and neck.
Review the “ Checklist for Obtaining a Nasal Swab ” for details about performing a nasal swab procedure.
