The nasal swab COVID-19 test is not painful, but it might be uncomfortable. Many have compared it to the feeling of water rushing up your nose. The swabbing procedure may result in your eyes watering, sneezing or coughing - this is completely normal! The technician will put a special cotton swab up one nostril and move it around for about 10 seconds. These nasal swab COVID-19 tests are called nasopharyngeal tests. It is a method for collecting a clinical test sample of nasal secretions from the back of the nose and throat.
Due to everyone's anatomy being different, the test might be more uncomfortable for some, and less for others. The important thing is that the test is done correctly, which our agents will make sure of.
