COVID-19 antigen test detects coronavirus in the mouth and throat. This test determines whether a case is presently infected with COVID-19. It's less accurate than PCR testing, still, as a high viral cargo is needed for the antigen test to descry the SARS-CoV-2 contagion (COVID-19). Some people in the early or late stages of infection may thus return a false result, although this isn't common. For further information visit the website https://www.globaltravelclinics.com/
