rapid naat test better than pcr


Rapid antigen tests are thought to be better than PCR tests at capturing when people are exiting the period of maximum infectiousness, since PCR tests are too sensitive. 1 Nucleic Acid Amplification Tests (NAATs) are a type of viral diagnostic test for SARS-CoV-2, the virus that causes COVID-19. 2 PCR tests are more accurate than rapid antigen tests, but rapid antigen tests are faster and less expensive. 3 The CDC recommends that all children, regardless of vaccination status, receive a CDC-approved Vaccine for SARS-CoV-2 test every six months. 2
