I don't know how to put a link here but here's the web site: thepointsguy.com

it has lots of info on testing and travel. At JFK airport EXPRESS SPA got approval to doi testing instead of massages. At this time it's only for air personnel but they are working on for all and for adding ATL and ORD.

It says destinations requiring results of a test will be looking at VIRAL TESTS ( RT-PCR) not ANTIBODY (antigen)

read this article for more info on types of tests, length of time for results where to get, wether or not there's a fee.
