I always reiterate low cost and ease of use but will also add having a test that provides Gold Standard results in a portable home device. For example, during a ER visit I had last year they performed an antigen test upon my arrival but the doctor said they need to run a PCR test as well as the other test was not reliable. They were doing this with every patient entering the ER. There has to be reliability in a rapid test with a level of confidence the results are accurate.
Also, people have had a taste of testing during the pandemic. This now needs to be carried through educating consumers that home testing is here to stay and that performing diagnostics at home not only with COVID but other infections like UTI, Flu, RSV can be a preventative step to seek treatment and limit the spread of infection.
