Do I need a certified ATK test for my visa application at Engwattana Immigration Office?

@Luke *********

I don’t think so; I’ve been to Chaengwattana several times this year (last was April) and even though there were signs and even a booth for ATK testing I was not required to do a test. The only mandatory thing is a health declaration which you will fill in before entering at Gate 2 Building B. If you want to be absolutely certain then do an ATK test before going, but a note from a doc or pharmacist is not necessary.
