I'm planning ahead for the PCR covid test required for travel to Thailand. The rule from the Thai website states "Such COVID-19 test result must be issued no more than 72 hours before departure". So does the clock on the 72 hours start clicking when my covid test is initiated in the clinic or when my covid test results are issued?
TLDR : Answer Summary
The 72-hour window for the COVID-19 PCR test required for entry into Thailand begins when the test results are issued, not when the test is taken. However, some airlines and transit countries may have different requirements, so it’s essential to check both those and time the test accordingly. For optimal results and to avoid complications at the airport, it's recommended to get tested as close to your travel date as possible and confirm local testing options that can provide timely results.
