In addition to PCR tests offered at medical offices, pharmacies and drive-thru and pop-up testing sites, some test kits allow people to collect their own sample at home and then send it off to a lab for PCR testing. These are different than the rapid at-home antigen tests that return ...
The two types of diagnostic tests discussed here are molecular lab-based PCR, which detects viral RNA, rapid PCR testing, and antigen-based testing, which detects viral proteins (the antigen). PCR and antigen testing are described more fully below to ...

If you recover from COVID and your symptoms come back within 90 days, don’t use a PCR test to see if you’re contagious again. Instead, choose an antigen test. If the result is negative, repeat it 48 hours later so you can trust the result. ...
Self-testing is an effective tool to bridge the testing gap for several infectious diseases; however, its performance in detecting SARS-CoV-2 using antigen-detection rapid diagnostic tests (Ag-RDTs) has not been systematically reviewed. This study aimed
This cohort study examines changes in the diagnostic performance of home antigen tests during the course of SARS-CoV-2 infection.
