I'm confused as to what you mean? Cases are recorded through positive tests sent to the CDC. (maybe after going to the white house first? I can't remember if they stopped doing that or not).
Testing requirements vary from state to state, but that's how cases are detected and how they derive the numbers.
I mean, if tests are done by random sampling, contact tracing, or by mass testing a la Chinese cities, then you get a whole lot of asymptomatics registering as cases. If you only test when people present at hospital, you get only the worst cases.

Yes, but the west outside of a handful of studies only tests when people show symptoms and don't do mass testing on any scale.
