The New Crown Antigen Self Test Kit is a nasal swab, and antigen self tests do not poke the nose and have no results. Using a pharyngeal swab to take a sample in the throat area gives the same results as a nasal swab. The antigen test is divided into two types of tests, a pharyngeal swab and a nasal swab, which can also be used as a basis for testing if the throat secretions are taken directly without poking the nose. Only the results that emerge from a sample taken from the throat area using a pharyngeal swab are diagnostic. However, antigen self-testing can only be used as a supplementary diagnostic option. If the antigen test is found to be positive, nucleic acid testing will be performed for diagnostic analysis, and if the test is still positive, the diagnosis is basically confirmed as a new coronavirus-infected person, and quarantine treatment will be required as soon as possible. However, in the antigen self-test, you need to pay attention to related matters, in the test before you must first wash your hands to disinfect sterilization, so as not to infect the specimen to affect the diagnostic results. If you are worried that improper operation will affect the diagnostic results, you can consult a professional physician.
