It's Bangkok hospital Rayong from where I got the results and call. I believe they have instructions to tell you to go in first to make money as 10k per day is not that bad.. They did not say how many days either but I have a feeling they would keep you as long as they could. As I knew you can isolate at home I said no as I don't have any symptoms even if they verified. They just sent the form I needed to fill in through google docs which was of course all in thai and the instructions for home isolation as well. I sent an email asking for English form and instructions but surprise, no reply... However later I'm going to go and get a paper from them that I have had covid so I can add it to our country's "vaccine passport"..
