Hi everyone. I am asking advice from UK people here, particularly if u are in London, of any clinic to do the Covid test with guaranteed results in 24-48 hours and prices.

I saw a lot of posts with contradictory information regarding the validity of the 72 hours Covid test required to enter Thailand and I checked with my airline, Etihad. As I change over in Abu Dhabi, I was informed that the hours count from the sample taken and needs to be within 72 of the whole flight/flights. Even the second one of your change over. Now I also wonder if We need to literally arrive in Bangkok too within 72 hours from the sample or as long as u are boarding it will be okay. Anyone flew with Etihad can share with me their experience ? And clinics where I can get the results in time please ? Thank you 🙏🏼
