New Crown Nucleic Acid Testing consists of two main types of tests: nasal swabs and pharyngeal swabs. Nasal swabs are swabs that are inserted into the nose of the person being tested; pharyngeal swabs are swabs that are inserted into the throat of the person being tested. 1. Nasal swabs: Nasal swabs are swabs that are inserted into the nose of the person being tested. The secretions from the person’s nose are collected as a specimen and finally sent to the laboratory for testing. 2. Pharyngeal swab: The pharyngeal swab is a swab that is inserted into the throat of the person being tested. The throat secretions or sputum are collected as a specimen and then transported to the laboratory for testing. It is important to take personal precautions and maintain a safe distance during the new crown nucleic acid test. Nucleic acid testing should not be performed within 48 hours of receiving the new crown vaccine.
