The PCR test is a fast test that gives a hint that maybe the virus is present. Of course they misused it by adjusting the tests so they gave way too many false positives. They finally scrapped it because antibody test are faster, more reliable, can be done at home, and are cheaper (< 1$ per test). They waited so long with approving the antibody tests because if everybody tests themselves and their children in the morning, lockdown and masks don't make any sense no more. Isolation of the virus is more expensive, but was done some hundred thousand times already.
