Last time we went to a clinic around the corner and got a PCR test for $50. We will do the same this time. It comes from a large, certified lab which I know is accepted. Why mess around with a self test kit to save a few bucks, but worry about it being accepted?

For returning to the US, a self-test kit is great because of the hassle of getting to Tortola to be tested within the three-day window.
