In a nutshell, pooled testing allows up to 10 tests to be pooled together. So if 9 healthy people are pooled with 1 truly positive test, all 10 tests will give a positive result.
Just another Deep State way to control spikes as needed for political control.
They get to decide, which areas of the country are spiking, whenever they want by using more or less pooled testing.

The scientific rationale behind pool testing is that they could potentially save test kits. If 10 people's samples are mixed into one test, and that test comes back negative, all samples are considered negative, and they saved 9 test kits. If the test comes back positive, they test them all individually (or in smaller pools) to determine who is actually positive. It's a good idea, but of course, it can be manipulated for evil reasons.
That's total bullshit.
They've spent what, $6T on Covid measures in the US? But that's where they're deciding to save a couple million?
It totally throws out the accuracy of said test.
It's not a question of money. There was a period of time when they couldn't make tests fast enough to meet the demand, and patients weren't allowed into hospitals for surgeries or diagnostic screenings without COVID testing. I agree that the tests are inaccurate bullshit anyway, but this was actually a clever solution to a supply problem.
