AFAIK there are different tests with varying accuracies. Those with low accuracy tend to be ran multiple times to help. Despite having to run multiple tests, capacity for these low accuracy tests is much higher than the tests the CDC attempted to distribute, and these are the types of tests countries with a huge number already tested have tended to use. Testing by local hospitals and universities in the USA has also been held up by FDA regulations that only recently (last week) were waived. The USA is behind this thing by a long shot. We are thinking about stuff now that we should have thought about at least a month ago. Another example is the federal government contemplating covering tests when insurance won't. The time to contemplate this was months ago, not today. This should have been decided, at the very latest, weeks ago so it could be rolled out at the proper time.
