The New Crown Antigen Test is usually only mildly uncomfortable. The New Crown Antigen Test is suitable for people under quarantine observation, community residents who have a need for antigen self-testing, and people with respiratory and fever symptoms. For self-testing, a nasal swab is held with the end of the swab against one nostril to gain access to the inside of the nose, then rotated against the nose to collect a sample and placed in a sampling tube. This process can cause some discomfort, but most people do not feel very uncomfortable and it is within the tolerable range. However, as each person is different, some people are more sensitive and may find it more difficult to perform the New Crown Antigen test. It is recommended to read the instructions and precautions related to antigen self-testing carefully to avoid operational errors. Observe the results after the test and seek medical attention if the result is positive.
