Today, there are dozens of tests to detect the novel corona virus. The NPV of antigen testing among asymptomatic participants was 98.8%, and virus was not cultured from asymptomatic participants with antigen-negative results, indicating that asymptomatic persons with negative antigen results are unlikely to be infected with SARS-CoV-2 and would not require confirmatory NAAT (1). Two follow-up tests, using a more accurate polymerase chain reaction, or PCR test, showed the governor didnt have the virus. Using summary results for people with no known exposure to COVID-19 in a bigger population of 10,000 people with no symptoms, where 50 (0.5%) of them really had COVID-19: 62 people would test positive for COVID-19. For specimens collected within 5 days of reported symptom onset (72.4%; 152 of 210), sensitivity was 74.2% (23 of 31), and specificity was 99.2% (120 of 121). Which is why you need the doctors offices and the dental offices to be running the tests. For people with no symptoms, tests were most accurate in people likely to have been in contact with a case of COVID-19 infection (an average of 64% of confirmed cases had positive antigen tests). Faster diagnosis of COVID-19 infection could allow people to take appropriate action more quickly, with the potential to reduce the spread of COVID-19, but it is important to understand how accurate they are and the best way to use them.

Today, there are dozens of tests to detect the novel corona virus. The NPV of antigen testing among asymptomatic participants was 98.8%, and virus was not cultured from asymptomatic participants with antigen-negative results, indicating that asymptomatic persons with negative antigen results are unlikely to be infected with SARS-CoV-2 and would not require confirmatory NAAT (1). Two follow-up tests, using a more accurate polymerase chain reaction, or PCR test, showed the governor didnt have the virus. Using summary results for people with no known exposure to COVID-19 in a bigger population of 10,000 people with no symptoms, where 50 (0.5%) of them really had COVID-19: 62 people would test positive for COVID-19.
