If you need a COVID test for airline travel on a specific date and time, look no more as this place is spot on! Everywhere I checked, no one could tell me with certainty when we'd receive our PCR COVID test results, and a matter of hours can make all the difference when it comes to meeting that "under 72 hour" test result requirement. Laura at QDX was not only able to tell me exactly when we should be swab tested but was also able to email the reports to me a day in advance! It worked out perfectly and I couldn't be happier with their service. Now, if only I can figure out how to upload these reports to United, we' ll be officially "travel ready". Good luck with that. read more
