Tests per day is a key number to track (along with actual cases and, sadly, deaths). But total tests were a key for South Korea slowing the spread of COVID-19. South Korea has been conducting 15,000 tests per day with about one-fifth of the US population, so the US needs to test 70,000 to 100,000 per day.

The US conducted 22,408 tests in the last 24 hours.  That is progress, but the US needs the ability to conduct about 70,000 to 100,000 per day.
