Hi we will be departing from Ljubljana in September transiting back to the US and will need a test. (This is assuming Slovenia is open in September, we are vaccinated already). I assume testing is going to long be required for entry/exit all over the world. Where can we get the testing done in Ljubljana before we leave? We need results with enough time to get on board our US flight within 72 hours of the test. Cost isn’t an issue. Thanks.
