I'm flying out of Thailand end of the month and need to do a PCR test 72 hours prior to departure. Does anyone know a reliable clinic near the airport which works 7 days a week and can deliver tests within 24 hours? I need a clinic which works Sundays as my flight is late Monday. If that is not available my second choice would be Phuket Town.

 

 

Not exactly near the airport.  But these clinics open daily and give "next day" results for PRC test.

The Australian government announced ATK/RAT test is good enough as well, this fixed the time limits for me, can do it the same day when flying.
