PCR
PCR can be considered analogous to a dogs sense of smell, acute and accurate, it can identify something from a trace.
When a dog detects a fox, it's the dog's sense of smell that detects that first trace, just one of the dogs many built in senses(tests) of a fox. Then the dog's eye, ears, teeth and taste buds confirm it's about to bite on a fox and not just a log the fox once sat on! Those other senses, the other tests the dog can do, determine the truth about the dog's detection.
When deniers or sceptics concentrate on PCR as a critique of Sars-CoV-2 testing. They expose a deeply flawed and fundamental lack of understanding how test, trace and diagnosis work. PCR is potentially just the smell of a virus, there are a host of other tests that confirm the diagnosis, lab tests, scans, observations from medical professionals, it is just that PCR is very very effective at detecting a trace of Sars-CoV-2.
