You would either take a test at a test site ( like Walgreens, minute clinic, your local clinic etc) or take a home proctored (observed) self test online via emed.com ( or similar). To self test using a proctor you need to have an internet connection, and your device needs a camera and audio capability. When test is complete you will be emailed a copy of your test results, You then upload a picture or scan of your test results into the Medallion App. I use Abbott Binaxnow ( the RX version) which can be ordered through Optum or Emed
