For the purpose of an international flight “each traveler must present the negative result of a PCR test no more than 96 hours before the stipulated time of travel.” How soon should I get the test done, in order to get the results, &need appointm?

The results are ready 20 minutes after you take the test. What you will do is go in register they'll give you a number that you can monitor on your phone. When it's your turn you will go in take your test and in 20 minutes you'll know. if you register early in the day the weight will be shorter.

i tried to schedule an app but it was walk-ins only. got there checked in and tracked my place in line through their app. about a 2 hour wait, got tested and came back for results in 45 min.
