Most of the testing that's done now is antigen testing looking for the virus. That's largely done byPCRR testing which looks for the DNA/RNA of the virus. It only tells you if you have a detectable level of the virus in the sample that was collected. You could have an undetectable level of the virus but be infected. The swab may have been collected improperly or handled improperly and missed an active infection giving you a false negative. The swab could get cross-contaminated at some point due to the volume of testing being done now and give you a false positive.
Testing is a tool, but it's not nearly as foolproof as many like to assume. It's far from a panacea. Oddly enough, temperature monitoring seems to have been most effective in China in containing the spread, if you believe the Chinese numbers. They reportedly had drones scanning people's temperatures as they walked on streets and even through their apartment windows and then dragging away and isolating anyone with even a slight fever.
That could prove most effective in containing the spread here if it's truly as simple as that. Monitor the temp of everyone entering or leaving a business, school, stadium, etc, and exclude those running a temp. Send them back home until their condition resolves. If a temperature occurs before the person is infectious, it would make containing this virus very easy. Taking temps can be done in a blink with modern tools these days and is a very fast, accurate and reliable test. No fever, come on in. Running a temp, go back home. Simple, fast, easy, and cost-effective.

And of course anyone you exposed on the bus into work, or while waiting on line to get your temperature🤒� tested, and while on your way home,
WILL NEED TO GO HOME AND STAY THERE TOO! See the problem?
But, one might well think 🧙♂️ testing is not the way to go,
as the often promised National tests that were supposed to 'be available to everyone who wants one' have failed to materialized - EVER.
