Can we get ART test at Phuket airport for an international flight?

We are going to Singapore flight at the same day flying from Phuket, Bangkok to Singapore. Where in Phuket we could take the ART Test before departure ?

Anyone knows if we can do pre departure ART test at Phuket airport/ Bangkok airport before departing for Singapore, and how long it will take to get the results? I searched but couldn't find the answer. Also, any suggestions where in Phuket to do pre-departure PCR test? I found a couple recommendations in the west and central but would like options in the east of Phuket. Thanks!
