the pcr tests detect the RNAs of the virus while the rapid antigen tests determine its proteins, I think. PCR tests are more accurate. However, since too many people are infected with the virus now, the medical providers can't be afford the huge amount of the PCR tests, the government suggested the antigen self tests at home to reduce the burdens of the test services in hospitals. The US government will send the self test kits to your home for free if you place an order starting from today. You can place your orders through the following link:
