Good for Serbia for implementing some centralized system. A PCR test result in the U.S has absolutely no way of being verified, either negative or positive In Israel, which swabs every person who lands at the airport. There is a suspiciously steady stream of people flying in from the U.S who were negative before take off and positive 10 minutes after landing
Doesn't the thread suggest someone has fiddled the system on Djokovic's behalf? If that's the case then the centralized PCR verification system is nothing but a house of cards.
Not when the test was made.
Normally that's the same.
But it's not enforced, as for example a test center which lost it's internet connection temporary is still allowed to add tests once the connection is back up.
So we don't know for sure that the test is manipulated.
We only know for sure that it was placed later in the system, not that it was made later.
Which is still very suspicious.
