False positives on the PCR test occur less than 1% of the time.

For the average person, they do not confirm the positive test via any other means. During the development and testing of the test itself, they did.

In my case, I let my son see 1 friend, 1 time. And he caught it. They were fishing at a lake, so there was no chance of exposure from anyone else.

His friend tested positive last week, and has not had any symptoms.
