Nasopharyngeal swabs, or “deep nasal swab,” go all the way up your nose and into your nasopharynx (these are very uncomfortable). These type of test must be performed by a medical professional.

Nasal swabs get inserted into the nostril until resistance is met. This test can be performed by the patient. It is not recommended for someone else to administer the test for the patient, unless they are a medical professional.
